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.

Palau's Rock Island Bay harbors a naturally occurring anomaly – its water is acidified as much as scientists expect the entire ocean to be by 2100 as a result of rising carbon dioxide emissions.

Benefits from protected forests such as improved water quality due to decreased runoff and increased distribution of the vegetation are more closely linked to coral reef health than previously thought.

An international audit of the health of the oceans has found that overfishing and pollution are also contributing to the crisis, in a deadly combination of destructive forces that are imperiling marine life, on which billions of people depend for their nutrition and livelihood.

Although global climate change and its effects on reefs via warming and acidification of coastal waters have made recent headlines, local human activities may destroy certain ecosystems before climate change has a chance to do it. The harmful effects of mining, agriculture, commercial development, and fishing in coastal regions have already damaged more than two-thirds of reefs across the Caribbean, in addition to worsening the negative effects of climate change.

The authors argue that despite numerous warnings that the Earth is headed toward an ecological tipping point due to environmental stressors, such as habitat loss or climate change, it's unlikely this will occur anytime soon&#8212;at least not on land. The paper comes with a number of caveats, including that a global tipping point could occur in marine ecosystems due to ocean acidification from burning fossil fuels. In addition, regional tipping points, such as the Arctic ice melt or the Amazon rainforest drying out, are still of great concern.

In its wake the massive superstorm left over 1,000 people were dead and 6.2 million affected with officials saying illegal logging and mining worsened the scale of the disaster. However, the Category 5 typhoon also left a trail of destruction that has been less reported: coral reefs.

It took until the 1970s before scientists realized the islands did in fact have coral, but in 1983, the year the first major report on Galapagos reef formation was published, they were almost obliterated by El Niño. This summer, a major coral survey found that some of the islands’ coral communities are showing promising signs of recovery. Their struggle to survive may tell us what is in store for the rest of the world, where almost three-quarters of corals are predicted to suffer long-term damage by 2030.

In a new survey in Conservation Biology, 99.5 percent of conservation scientists said a serious loss in biodiversity was either 'likely', 'very likely', or 'virtually certain'. The prediction of a significant loss of species is not surprising&#8212;scientists have been warning for decades that if global society continues with business as usual the world will suffer from mass extinction&#8212;what is perhaps surprising is the practically unanimous expectation that a global biodiversity decline will occur.

The bleak assessment finds that the world's oceans are in a significantly worse state than has been widely recognized, although past reports of this nature have hardly been uplifting. The panel, organized by the International Program on the State of the Ocean (IPSO), found that overfishing, pollution, and climate change are synergistically pummeling oceanic ecosystems in ways not seen during human history. Still, the scientists believe that there is time to turn things around if society recognizes the need to change.

But a new comprehensive analysis by the World Resources Institute (WRI) along with twenty-five partners ups the ante, finding that 75% of the world's coral reefs are threatened by local and global impacts, including climate change. An updating of a 1996 report, the new analysis found that threats had increased on 30% of the world's reefs. Clearly conservation efforts during the past decade have failed to save reefs on a large-scale.

Due to a variety of factors—including ocean acidification, warming temperatures from climate change, overfishing, and pollution—coral cover has decline by approximately 125,000 square kilometers in the past 50 or so years. This has caused some marine biologists, like Charlie Veron, Former Chief Scientist of the Australian Institute of Marine Science, to predict that coral reefs will be largely extinguished within a century. This year alone, large-scale coral bleaching events, whereby coral lose their symbiotic protozoa and become prone to disease and mortality, were seen off the coasts of Indonesia, the Philippines, and some Caribbean islands. However a new paper in <i>Trends in Ecology and Evolution</i> attempts to dispel the gloom over coral reefs by pointing to strategies, and even some successes, to save them.

Already, species have provided humankind everything from quinine to aspirin, from morphine to numerous cancer and HIV-fighting drugs. "As the ethnobotanist Dr. Mark Plotkin commented, the history of medicine can be written in terms of its reliance on and utilization of natural products," physician Christopher Herndon told mongabay.com.

In fact, coral reefs are one of the most diverse ecosystems on earth. It is not unusual for a reef to have several hundred species of snails, sixty species of corals, and several hundred species of fish. While they comprise under 1% of the world’s ocean surface, one-quarter of all marine species call coral reefs their home. Fish, mollusks, sea stars, sea urchins, and more depend on this important ecosystem, and humans do too. Coral reefs supply important goods and services–from shoreline protection to tourism and fisheries–which by some estimates are worth $375 billion a year.

However, coral reefs are one of the most threatened ecosystems in the world due to many factors, such as global warming and ocean acidification. Recent research by Simpson and his team of scientists has shown that corals, rather than drifting aimlessly after being released by their parent colonies and by chance landing back on reefs, instead find their way purposefully to reefs by detecting the sound of snapping shrimps and grunting fish on the reef. However, that discovery also means that the larvae might struggle to find reefs when human noises, like drilling or boats, mask the natural ocean sounds.

Although corals face many threats, the greatest is bleaching caused by warming oceans due to climate change. However, some coral populations are more susceptible to bleaching than others, even including corals of the same species.
