News articles on population
Mongabay.com news articles on population in blog format. Updated regularly.
(10/16/2013) Sir David Attenborough has said that people living in poorer countries are just as concerned about the environment as those in the developed world, and "exporting environmentalism" isn't necessarily an "uphill struggle". The veteran broadcaster said ideas about protecting the natural world were not unwelcome in less developed nations—but added that wealthier countries should work to improve women's rights around the world to bring down birth rates and avoid overpopulation.
Humanity consumes this year's resources 133 days too early
(08/20/2013) Today is Earth Overshoot Day, according to the Global Footprint Network and WWF's Living Planet Report, which means the seven billion people on Earth have consumed the globe's renewable resources for the year. In other words for the next 133 days humanity will be accumulating ecological debt by overdrawing on our collective resources.
Foodies eat lab-grown burger that could change the world
(08/06/2013) Yesterday at a press event in London, two food writers took a bite into the world's most unusual hamburger. Grown meticulously from cow stem cells, the hamburger patty represents the dream (or pipedream) of many animal rights activists and environmentalists. The burger was developed by Physiologist Mark Post of Maastricht University and funded by Google co-founder Sergey Brin in an effort to create real meat without the corresponding environmental toll.
The neglected giraffe: world's tallest animal in need of conservation assistance
(06/27/2013) Just two year's before his assassination, Julius Caesar brought to Rome one of the world's most astonishing living creatures: a giraffe. The animal was among Caesar's spoils from his campaign in Egypt and according to the Roman writer, Dio, the giraffe, which was arguably the first to ever touch European soil, was paraded in the Circus for all to see. Today, over two thousand years later, the giraffe has become one of the world's most recognizable animals: after all nothing looks quite like it with its spotted coat, tufted horns, and, most importantly, that impossibly long neck. But less commonly known is that the giraffe is in trouble with some subspecies down to just a few hundred individuals.
Crop yields no longer keeping up with population growth
(06/26/2013) If the world is to grow enough food for the projected global population in 2050, agricultural productivity will have to rise by at least 60%, and may need to more than double, according to researchers who have studied global crop yields.
Building a new generation of local conservationists: how improving education in Uganda may save one of the world's great forests
(06/20/2013) Conservation work is often focused on the short-term: protecting a forest from an immediate threat, saving a species from pending extinction, or a restoring an ecosystem following degradation. While short-term responses are often borne of necessity, one could argue that long-term thinking in conservation and environmental work (as in all human endeavors) is woefully neglected, especially in the tropics. This is why programs like the Kasiisi Project are so important: by vastly improving education for primary kids near a threatened park in Uganda, the project hopes to create a "generation of committed rural conservationists," according to founder and director, Elizabeth Ross.
Fertility in Africa could push world population over 11 billion
(06/13/2013) The global population could grow by another 4 billion people by the end of the century if fertility rates in Africa don't decline, according to a new report by the United Nations. Currently around 1.1 billion people live on the continent, but that number could skyrocket to 4.2 billion (a 380 percent increase) by 2100, causing global population to hit 11 billion.
Saving Gorongosa: E.O. Wilson on protecting a biodiversity hotspot in Mozambique
(05/30/2013) If you fly over the Great African Rift Valley from its northernmost point in Ethiopia, over the great national parks of Kenya and Tanzania, and follow it south to the very end, you will arrive at Gorongosa National Park in central Mozambique. Plateaus on the eastern and western sides of the park flank the lush valley in the center. Dramatic limestone cliffs, unexplored caves, wetlands, vast grasslands, rivers, lakes, and a patchwork of savanna and forest contribute to the incredible diversity of this park. What makes this place truly unique, however, is Mount Gorongosa—a towering massif that overlooks the valley below.
Over 500 scientists warn we 'are causing alarming levels of harm to our planet'
(05/27/2013) A new consensus statement by 520 scientists from around the world warns that global environmental harm is putting at risk the happiness and well-being of this and future generations.
Eat insects to mitigate deforestation and climate change
(05/14/2013) A new 200-page-report by the UN Food and Agriculture Organization (FAO) urges human society to utilize an often-ignored, protein-rich, and ubiquitous food source: insects. While many in the industrialized west might turn up their noses at the idea of eating insects, already around 2 billion people worldwide eat over 1,900 species of insect, according to the FAO. Expanding insect-eating, the authors argue, may be one way to combat rising food needs, environmental degradation, and climate change.
The river of plenty: uncovering the secrets of the amazing Mekong
(04/23/2013) Home to giant catfish and stingrays, feeding over 60 million people, and with the largest abundance of freshwater fish in the world, the Mekong River, and its numerous tributaries, brings food, culture, and life to much of Southeast Asia. Despite this, little is known about the biodiversity and ecosystems of the Mekong, which is second only to the Amazon in terms of freshwater biodiversity. Meanwhile, the river is facing an existential crisis in the form of 77 proposed dams, while population growth, pollution, and development further imperil this understudied, but vast, ecosystem.
An insidious threat to tropical forests: over-hunting endangers tree species in Asia and Africa
(04/04/2013) A fruit falls to the floor in a rainforest. It waits. And waits. Inside the fruit is a seed, and like most seeds in tropical forests, this one needs an animal—a good-sized animal—to move it to a new place where it can germinate and grow. But it may be waiting in vain. Hunting and poaching has decimated many mammal and bird populations across the tropics, and according to two new studies the loss of these important seed-disperser are imperiling the very nature of rainforests.
Scientists: stop treating population growth as a 'given' and empower women
(02/27/2013) Climate change, biodiversity loss, resource depletion, water scarcity, and land issues: almost all of the world's environmental problems are underpinned by too many people inhabiting a finite planet. A new study in the Proceedings of the Royal Society B warns that overpopulation—combined with over-consumption—is threatening to push the entire globe into "a collapse of global civilization." But cultural changes, especially more empowerment of women and access to contraceptives, may hold the key to reducing population growth and eventual sustainability.
A second look at 'Fewer, Richer, Greener: The End of the Population Explosion and the Future for Investors'
(01/14/2013) Fewer, Richer, Greener: The End of the Population Explosion and the Future for Investors (November/December 2012, Vol. 68, No. 6: 20–37), by Mr. Laurence B. Siegel provides us with a commentary of population explosion and green investment opportunities over the long-run.
Paradigm shift needed to avert global environmental collapse, according to author of new book The Blueprint: Averting Global Collapse
(01/10/2013) Global strategist, trained educator, and international lecturer Daniel Rirdan set out to create a plan addressing the future of our planet. His book The Blueprint: Averting Global Collapse, published this year, does just that. "It has been a sixty hour a week routine," Rirdan told mongabay.com in a recent interview. "Basically, I would wake up with the burden of the world on my shoulders and go to sleep with it. It went on like this for eighteen months." It becomes apparent when reading The Blueprint that it was indeed a monumental undertaking.
Forests, farming, and sprawl: the struggle over land in an Amazonian metropolis
(12/04/2012) The city of Parauapebas, Brazil is booming: built over the remains of the Amazon rainforest, the metropolis has grown 75-fold in less than 25 years, from 2,000 people upwards of 150,000. But little time for urban planning and both a spatial and mental distance from the federal government has created a frontier town where small-scale farmers struggle to survive against racing sprawl, legal and illegal mining, and a lack of investment in environmental protection. Forests, biodiversity, and subsistence farmers have all suffered under the battle for land. In this, Parauapebas may represent a microcosm both of Brazil's ongoing problems (social inequality, environmental degradation, and deforestation) and opportunity (poverty alleviation, reforestation, and environmental enforcement).
Wolves, mole rats, and nyala: the struggle to conserve Ethiopia's highlands
(11/20/2012) There is a place in the world where wolves live almost entirely off mountain rodents, lions dwell in forests, and freshwater rolls downstream to 12 million people, but the place—Ethiopia's Bale Mountains National Park—remains imperiled by a lack of legal boundaries and encroachment by a growing human population. "Much of the land in Africa above 3,000 meters has been altered or degraded to the point where it isn’t able to perform most of the ecosystem functions that it is designed to do. Bale, although under threat and already impacted to a degree by anthropogenic activities, is still able to perform its most important ecosystem functions, and as such ranks among only a handful of representative alpine ecosystems in Africa."
Illegal hunting threatens iconic animals across Africa's great savannas, especially predators
(10/25/2012) Bushmeat hunting has become a grave concern for species in West and Central Africa, but a new report notes that lesser-known illegal hunting in Africa's iconic savannas is also decimating some animals. Surprisingly, illegal hunting across eastern and southern Africa is hitting big predators particularly hard, such as cheetah, lion, leopard, and wild dog. Although rarely targets of hunters, these predators are running out of food due to overhunting and, in addition, often becoming victims of snares set out for other species.
One in eight people suffer from malnutrition worldwide
(10/16/2012) In a world where technology has advanced to a point where I can instantly have a face-to-face conversation via online video with a friend in Tokyo, nearly 870 million people, or one in eight, still suffer from malnutrition, according to a new UN report. While worldwide hunger declined from 1990 to 2007, progress was slowed by the global economic crisis. Over the last few years, numerous and record-breaking extreme weather events have also taken tolls on food production. Currently, food prices hover just below crisis levels.
Forest cover falls 9% in East Africa in 9 years
(07/31/2012) Forest cover in East Africa has dropped by 9.3 percent from 2001-2009, according to a new paper published in the open-access journal PLoS ONE. Looking at 12 countries in the region, the scientists found that, worryingly, forests were particularly hard hit near protected areas. Usually thought of as a region of vast savannas, such as the Serengeti, East Africa is also home to incredibly biodiverse tropical forests, including coastal forests, rich montane forests, and the eastern portion of the Congo Rainforest.
Cowards at Rio?: organizations decry 'pathetic' agreement
(06/20/2012) As world leaders head to Rio de Janeiro for the UN Summit on Sustainable Development, environmental and poverty groups are denouncing the last-minute text agreed on by dignitaries as "pathetic," (Greenpeace), a "damp squib" (Friends of the Earth), "a dead end" (Oxfam), and, if nothing changes, "a colossal waste of time" (WWF). "We were promised the 'future we want' but are now being presented with a 'common vision' of a polluter’s charter that will cook the planet, empty the oceans and wreck the rain forests,“ the head of Greenpeace, Kumi Naidoo, said. "This is not a foundation on which to grow economies or pull people out of poverty, it’s the last will and testament of a destructive twentieth century development model."
Scientists: if we don't act now we're screwed
(06/07/2012) Scientists warn that the Earth may be reaching a planetary tipping point due to a unsustainable human pressures, while the UN releases a new report that finds global society has made significant progress on only four environmental issues out of ninety in the last twenty years. Climate change, overpopulation, overconsumption, and ecosystem destruction could lead to a tipping point that causes planetary collapse, according to a new paper in Nature by 22 scientists. The collapse may lead to a new planetary state that scientists say will be far harsher for human well-being, let alone survival.
Consumption, population, and declining Earth: wake-up call for Rio+20
(05/15/2012) Currently, human society is consuming natural resources as if there were one-and-a-half Earths, and not just a single blue planet, according to the most recent Living Planet Report released today. If governments and societies continue with 'business-as-usual' practices, we could be consuming three years of natural resources in 12 months by 2050. Already, this ecological debt is decimating wildlife populations worldwide, disproportionately hurting the world's poor and most vulnerable, threatening imperative resources like food and water, heating up the atmosphere, and risking global well-being.
Educating the next generation of conservation leaders in Colombia
(05/14/2012) Colombia's northern departments of Cordoba and Bolivar are home to an abundance of coral reefs, estuaries, mangroves forests, and forests. Rich in both marine and terrestrial wildlife, local communities depend on the sea and land for survival, yet these ecosystems are imperiled by booming populations, overexploitation, and unsustainable management. Since 2007, an innovative education program in the region, the Guardians of Nature, has worked to teach local children about the ecology of the region, hoping to instill a conservation ethic that will aid both the present and the future.
Top 10 Environmental Stories of 2011
(12/22/2011) Many of 2011's most dramatic stories on environmental issues came from people taking to the streets. With governments and corporations slow to tackle massive environmental problems, people have begun to assert themselves. Victories were seen on four continents: in Bolivia a draconian response to protestors embarrassed the government, causing them to drop plans to build a road through Tipnis, an indigenous Amazonian reserve; in Myanmar, a nation not known for bowing to public demands, large protests pushed the government to cancel a massive Chinese hydroelectric project; in Borneo a three-year struggle to stop the construction of a coal plant on the coast of the Coral Triangle ended in victory for activists; in Britain plans to privatize forests created such a public outcry that the government not only pulled back but also apologized; and in the U.S. civil disobedience and massive marches pressured the Obama Administration to delay a decision on the controversial Keystone XL pipeline, which would bring tar sands from Canada to a global market.
11 challenges facing 7 billion super-consumers
(10/31/2011) Perhaps the most disconcerting thing about Halloween this year is not the ghouls and goblins taking to the streets, but a baby born somewhere in the world. It's not the baby's or the parent's fault, of course, but this child will become a part of an artificial, but still important, milestone: according to the UN, the Earth's seventh billionth person will be born today. That's seven billion people who require, in the very least, freshwater, food, shelter, medicine, and education. In some parts of the world, they will also have a car, an iPod, a suburban house and yard, pets, computers, a lawn-mower, a microwave, and perhaps a swimming pool. Though rarely addressed directly in policy (and more often than not avoided in polite conversations), the issue of overpopulation is central to environmentally sustainability and human welfare.
Five ways to feed billions without trashing the planet
(10/13/2011) At the end of this month the UN predicts global population will hit 7 billion people, having doubled from 3.5 billion in less than 50 years. Yet even as the Earth hits this new milestone, one billion people do not have enough food; meanwhile the rapid expansion of agriculture is one of the leading causes of global environmental degradation, including greenhouse gas emissions, destruction of forests, marine pollution, mass extinction, water scarcity, and soil degradation. So, how do we feed the human population—which continues to rise and is expected to hit nine billion by 2050—while preserving the multitude of ecosystem services that support global food production? A new study in Nature proposes a five-point plan to this dilemma.
UN calls for secure contraceptives as wildlife group hands out Endangered Species condoms
(10/06/2011) Sometime at the end of this month, the seventh billion person on Earth will be born: that's seven billions mouths to feed, seven billion throats to water, and seven billion bodies to keep warm. But the population continues to rise: experts believe the global human population could hit 10 billion by 2050. A UN meeting last month said that to meet the needs of the world's women, the developing world needs a secure supply of contraceptives and voluntary family planning initiatives.
Balancing agriculture and rainforest biodiversity in India’s Western Ghats
(08/08/2011) When one thinks of the world's great rainforests the Amazon, Congo, and the tropical forests of Southeast Asia and Indonesia usually come to mind. Rarely does India—home to over a billion people—make an appearance. But along India’s west coast lies one of the world's great tropical forests and biodiversity hotspots, the Western Ghats. However it's not just the explosion of life one finds in the Western Ghats that make it notable, it's also the forest's long—and ongoing—relationship to humans, lots of humans. Unlike many of the world's other great rainforests, the Western Ghats has long been a region of agriculture. This is one place in the world where elephants walk through tea fields and tigers migrate across betel nut plantations. While wildlife has survived alongside humans for centuries in the region, continuing development, population growth and intensification of agriculture are putting increased pressure on this always-precarious relationship. In a recent paper in Biological Conservation, four researchers examine how well agricultural landscapes support biodiversity conservation in one of India's most species-rich landscapes.
Protected areas not enough to save life on Earth
(08/03/2011) Since the creation of Yellowstone National Park in 1872 protected areas have spread across the world. Today, over 100,000 protected areas—national parks, wildlife refuges, game reserves, marine protected areas (MPAs), wildlife sanctuaries, etc.—cover some 7.3 million square miles (19 million kilometers), mostly on land, though conservation areas in the oceans are spreading. While there are a number of reasons behind the establishment of protected areas, one of the most important is the conservation of wildlife for future generations. But now a new open access study in Marine Ecology Progress Series has found that protected areas are not enough to stem the loss of global biodiversity. Even with the volume of protected areas, many scientists say we are in the midst of a mass extinction with extinction levels jumping to 100 to 10,000 times the average rate over the past 500 million years. While protected areas are important, the study argues that society must deal with the underlying problems of human population and overconsumption if we are to have any chance of preserving life on Earth—and leaving a recognizable planet for our children.
Richard Leakey: 'selfish' critics choose wrong fight in Serengeti road
(07/02/2011) The controversial Serengeti road is going ahead, but with conditions. According to the Tanzanian Minister for Natural Resources and Tourism, Ezekiel Maige, the road will not be paved and it will be run by the Tanzanian park authority who will have the power to monitor traffic to 'ensure no harm comes to the wildlife population'. Critics argue that even an unpaved road would eventually cripple the largest land migration in the world. However, famed Kenyan conservationist, ex-politician, and anthropologist, Richard Leakey, told mongabay.com that critics of the road are focusing on the wrong fight while failing to respect Tanzania's right to develop. Leakey says that instead of attempting to stop the road from being built, which he believes is inevitable, critics should instead focus on funding a truly wildlife-friendly road.
How do tourists view the Serengeti?
(06/27/2011) Serengeti National Park in Tanzania, an immense expanse of East African savanna, is a world famous tourist destination because of its plentiful megafauna, particularly the great migrating herds of wildebeest. Yet despite huge visitor numbers and the annual revenue of millions of US dollars, local poverty and increasing population continue to imperil the reserve. A new study in mongabay.com's open-access journal Tropical Conservation Science found that while tourists to the Serengeti overall report a high degree of satisfaction with their trip, they are concerned about the future of the ecosystem.
Nobel laureates: 'we are transgressing planetary boundaries that have kept civilization safe for the past 10,000 years'
(05/23/2011) Last week the 3rd Nobel Laureates Symposium on Global Sustainability concluded with participants—including 17 past Nobel Prize winners and 40 other experts—crafting and signing the Stockholm Memorandum. The document calls for emergency actions to tackle human pressures on the Earth's environment while ensuring a more equitable and just world.
US southern forests face bleak future, but is sprawl or the paper industry to blame?
(05/19/2011) More people, less forests: that's the conclusion of a US Forest Service report for forests in the US South. The report predicts that over the next 50 years, the region will lose 23 million acres (9.3 million hectares) largely due to urban sprawl and growing populations amid other factors. Such a loss, representing a decline of over 10 percent, would strain ecosystem services, such as water resources, while potentially imperiling over 1,000 species. However, Dogwood Alliance, which campaigns for conservation of southern forests criticizes the new report for underplaying the role of clearcutting natural forests for the paper industry in the south.
From the Serengeti to Lake Natron: is the Tanzanian government aiming to destroy its wildlife and lands?
(04/14/2011) What's happening in Tanzania? This is a question making the rounds in conservation and environmental circles. Why is a nation that has so much invested in its wild lands and wild animals willing to pursue projects that appear destined not only to wreak havoc on the East African nation's world-famous wildlife and ecosystems, but to cripple its economically-important tourism industry? The most well known example is the proposed road bisecting Serengeti National Park, which scientists, conservationists, the UN, and foreign governments alike have condemned. But there are other concerns among conservationists, including the fast-tracking of soda ash mining in East Africa's most important breeding ground for millions of lesser flamingo, and the recent announcement to nullify an application for UNESCO Heritage Status for a portion of Tanzania's Eastern Arc Mountains, a threatened forest rich in species found no-where else. According to President Jakaya Kikwete, Tanzania is simply trying to provide for its poorest citizens (such as communities near the Serengeti and the Eastern Arc Mountains) while pursuing western-style industrial development.
What's behind the 85% decline of mammals in West Africa's parks?
(03/28/2011) A recent, well-covered study found that African mammals populations are in steep decline in the continent's protected areas. Large mammal populations over forty years have dropped by 59% on average in Africa [read an interview on the study here] and by 85% in west and central Africa, according to the study headed by Ian Craigie, which links the decline to continuing habitat degradation as well as hunting and human-wildlife conflict. However, a new opinion piece in mongabay.com's open access journal Tropical Conservation Science argues that this study missed an important factor in central and west Africa where the decline in mammals was the worst: rainfall.
India government: forest target 'unrealistic'
(03/20/2011) Not long ago much of India was covered in vast and varied forests. Today just over one-fifth (21%) of the nation remains under forest cover, according to the Food and Agriculture Organization (FAO) but an ambitious plan hopes to bring the forest cover percentage to 33%, or one third of the country. However that goal has been dubbed 'unrealistic' by India's influential Minister for Environment and Forests, Jairam Ramesh, as reported by The Hindu.
Parks key to saving India's great mammals from extinction
(02/24/2011) Krithi Karanth grew up amid India's great mammals—literally. Daughter of conservationist and scientist Dr. Ullas Karanth, she tells mongabay.com that she saw her first wild tigers and leopard at the age of two. Yet, the India Krithi Karanth grew up in may be gone in a century, according to a massive new study by Karanth which looked at the likelihood of extinction for 25 of India's mammals, including well-known favorites like Bengal tigers and Asian elephants, along with lesser known mammals (at least outside of India) such as the nilgai and the gaur. The study found that given habitat loss over the past century, extinction stalked seven of India's mammals especially: Asiatic lions, Bengal tigers, wild dogs (also known as dholes), swamp deer, wild buffalo, Nilgiri Tahr, and the gaur. However, increasing support of protected areas and innovative conservation programs outside of parks would be key to saving India's wildlife in the 21st Century.
The ocean crisis: hope in troubled waters, an interview with Carl Safina
(02/07/2011) Being compared—by more than one reviewer—to Henry Thoreau and Rachel Carson would make any nature writer's day. But add in effusive reviews that compare one to a jazz musician, Ernest Hemingway, and Charles Darwin, and you have a sense of the praise heaped on Carl Safina for his newest work, The View from Lazy Point: A Natural Year in an Unnatural World. Like Safina's other books, The View from Lazy Point focuses on the beauty, poetry, and crisis of the world's oceans and its hundreds-of-thousands of unique inhabitants. Taking the reader on a journey around the world—the Arctic, Antarctic, and the tropics—Safina always returns home to take in the view, and write about the wildlife of his home, i.e. Lazy Point, on Long Island. While Safina's newest book addresses the many ways in which the ocean is being degraded, depleted, and ultimately imperiled as a living ecosystem (such as overfishing and climate change) it also tweezes out stories of hope by focusing on how single animals survive, and in turn how nature survives in an increasingly human world. However, what makes Safina's work different than most nature writing is his ability to move seamlessly from contemporary practical problems to the age-old philosophical underpinnings that got us here. By doing so, he points a way forward.
Paradise & Paradox: a semester in Ecuador
(02/02/2011) A semester abroad is an opportunity to live a sort of compacted life. In a few short months you seem to gain the experience of a much longer time and make enough memories to fill years. I recall a weeklong trip to the Alvord Desert with a field biology class from Portland Community College: the adventure of living out of a van, conducting research, and experiencing a place with classmates turned colleagues and professors turned friends who knew the desert like the backs of their hands. In that regard, it had a lot in common with my semester in Ecuador, but I can't think of anything that could have prepared me for a four month stay in a small South American country that I knew very little about.
From Cambodia to California: the world's top 10 most threatened forests
(02/02/2011) Growing populations, expanding agriculture, commodities such as palm oil and paper, logging, urban sprawl, mining, and other human impacts have pushed many of the world's great forests to the brink. Yet scientists, environmentalists, and even some policymakers increasingly warn that forests are worth more standing than felled. They argue that by safeguarding vulnerable biodiversity, sequestering carbon, controlling erosion, and providing fresh water, forests provide services to humanity, not to mention the unquantifiable importance of having wild places in an increasingly human-modified world. Still, the decline of the world's forests continues: the FAO estimating that around 10 million hectares of tropical forest are lost every year. Of course, some of these forests are more imperiled than others, and a new analysis by Conservation International (CI) has catalogued the world's 10 most threatened forests.
Africa's vanishing wild: mammal populations cut in half
(01/27/2011) The big mammals for which Africa is so famous are vanishing in staggering numbers. According to a study published last year: Africa's large mammal populations have dropped by 59% in just 40 years. But what is even more alarming was that the study only looked at mammal populations residing in parks and wildlife areas, i.e. lands that are, at least on paper, under governmental protection. Surveying 78 protected areas for 69 species, the study included global favorites such as the African elephant, giraffes, zebra, wildebeest, and even Africa's feline king, the lion. "We weren’t surprised that populations had dropped but we were surprised by how large the drops had been," lead author Ian Craigie told mongabay.com in an interview.
Census: 308.7 million people live in the United States
(12/22/2010) 308,745,538 people were living in the United States on April 1, 2010, according to the U.S. Census Bureau.
Lack of schools, trade drive exodus from remote parts of the Amazon
(12/17/2010) Lack of school access and higher costs of trade are driving an exodus from remote areas in the Amazon, a new study published in Population & Environment reveals. The research sheds light on to why people are leaving remote forest areas. It follows an earlier publication indicating that migration away from remote rural areas may have repercussions on deforestation.
Jane Goodall and David Attenborough: overpopulation must be addressed
(12/06/2010) In a recent interview with The Telegraph world famous primatologist and conservationist, Jane Goodall, and wildlife documentarian Sir David Attenborough agreed that overpopulation must be addressed to protect the global environment.
It's not just size that matters: how population affects climate change
(11/11/2010) As the world's population increases, a surge in the number of older adults and the movement of people from the countryside to crowded cities will significantly affect levels of carbon dioxide emissions by 2050, according to a sweeping study published in the 11 October issue of the Proceedings of the National Academy of Sciences. A significant but attainable slowing of the planet's growing population could achieve up to 29 percent of the total decrease in emissions needed to stave off the harmful consequences of climate change by 2050, according to the study.
Undergrads in the Amazon: American students witness beauty and crisis in Yasuni National Park, Ecuador
(10/28/2010) Although most Americans have likely seen photos and videos of the world's largest rainforest, the Amazon, they will probably never see it face-to-face. For many, the Amazon seems incredibly remote: it is a dim, mysterious place, a jungle surfeit in adventure and beauty—but not a place to take a family vacation or spend a honeymoon. This means that the destruction of the Amazon, like the rainforest itself, also appears distant when seen from Oregon or North Carolina or Pennsylvania. Oil spills in Ecuador, cattle ranching in Brazil, hydroelectric dams in Peru: these issues are low, if not non-existent, for most Americans. But a visit to the Amazon changes all that. This was recently confirmed to me when I traveled with American college students during a trip to far-flung Yasuni National Park in Ecuador. As a part of a study abroad program with the University of San Francisco in Quito and the Galapagos Academic Institute for the Arts and Sciences (GAIAS), these students spend a semester studying ecology and environmental issues in Ecuador, including a first-time visit to the Amazon rainforest at Tiputini Biodiversity Station in Yasuni—and our trips just happened to overlap.
Humanity consuming the Earth: by 2030 we'll need two planets
(10/13/2010) Too many people consuming too much is depleting the world's natural resources faster than they are replenished, imperiling not only the world's species but risking the well-being of human societies, according to a new massive study by the World Wildlife Fund (WWF), entitled the Living Planet Report. The report finds that humanity is currently consuming the equivalent of 1.5 planet Earths every year for its activities. This overconsumption has caused biodiversity—in this case, representative populations of vertebrate animals—to fall by 30 percent worldwide since 1970. The situation is more dire in tropical regions where terrestrial species' populations have fallen by 60 percent and freshwater species by 70 percent.
Farms in the sky, an interview with Dickson Despommier
(10/12/2010) To solve today's environmental crises—climate change, deforestation, mass extinction, and marine degradation—while feeding a growing population (on its way to 9 billion) will require not only thinking outside the box, but a "new box altogether" according to Dr. Dickson Despommier, author of the new book, The Vertical Farm. Exciting policy-makers and environmentalists, Despommier's bold idea for skyscrapers devoted to agriculture is certainly thinking outside the box.
Fighting poachers, going undercover, saving wildlife: all in a day's work for Arief Rubianto
(09/29/2010) Arief Rubianto, the head of an anti-poaching squad on the Indonesian island of Sumatra best describes his daily life in this way: "like mission impossible". Don't believe me? Rubianto has fought with illegal loggers, exchanged gunfire with poachers, survived four days without food in the jungle, and even gone undercover—posing as a buyer of illegal wildlife products—to infiltrate a poaching operation. While many conservationists work from offices—sometimes thousands of miles away from the area they are striving to protect—Rubianto works on the ground (in the jungle, in flood rains, on rock faces, on unpredictable seas, and at all hours of the day), often risking his own life to save the incredibly unique and highly imperiled wildlife of Sumatra.
