Human impacts are 'decoupling' coral reef ecosystems
(03/09/2015) There is a growing consensus among scientists that we have entered the age of the Anthropocene, or the epoch of humans. In other words, at some point between the 12,000 years separating the beginning of agriculture and the Industrial Revolution, humans became the dominant source of change on the planet, shaping everything from the land to the atmosphere to even the geologic record where we etch our reign.
Without draconian measures, global population boom is 'locked in'
(12/01/2014) According to recent projections, the number of people living on Earth could exceed ten billion by the end of this century. Now, a new study has examined what it would take to reverse that unrelenting growth and achieve a sustainable population that is less threatening to biodiversity and ecosystems around the world.
World population could surpass 13 BILLION by the end of the century
(09/18/2014) By 2100, over 13 billion people could be walking the planet. That's the conclusion of a new study published today in Science, which employed UN data to explore the probability of various population scenarios. The new study further demolishes the long-held theory that human population growth will quit growing by mid-century and then fall.
Booming populations, rising economies, threatened biodiversity: the tropics will never be the same
(07/07/2014) For those living either north or south of the tropics, images of this green ring around the Earth's equator often include verdant rainforests, exotic animals, and unchanging weather; but they may also be of entrenched poverty, unstable governments, and appalling environmental destruction. A massive new report, The State of the Tropics, however, finds that the truth is far more complicated.
Unrelenting population growth driving global warming, mass extinction
(06/26/2014) It took humans around 200,000 years to reach a global population of one billion. But, in two hundred years we've septupled that. In fact, over the last 40 years we've added an extra billion approximately every dozen years. And the United Nations predicts we'll add another four billion—for a total of 11 billion—by century's end.
Over 75 percent of large predators declining
(01/09/2014) The world's top carnivores are in big trouble: this is the take-away message from a new review paper published today in Science. Looking at 31 large-bodied carnivore species (i.e those over 15 kilograms or 33 pounds), the researchers found that 77 percent are in decline and more than half have seen their historical ranges decline by over 50 percent. In fact, the major study comes just days after new research found that the genetically-unique West African lion is down to just 250 breeding adults.
Lions face extinction in West Africa: less than 250 survive
(01/08/2014) The lions of West Africa, which may represent a distinct subspecies, are on the precipice of extinction. A sober new study in PLOS ONE reports that less than 250 mature lions survive in the region. Scientists have long known that West Africa's lions were in trouble, but no one expected the situation to be as dire as it was. In fact, in 2012 scientists estimated the population at over 500. But looking at 21 parks, scientists were shocked to find lions persisted in just four with only one population containing more than 50 individuals.
David Attenborough: someone who believes in infinite growth is 'either a madman or an economist'
(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.
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.
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.
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.
