New York times: Ocean Life Faces Mass Extinction, Broad Study Says
A team of scientists, in a groundbreaking analysis of data from hundreds of sources, has concluded that humans are on the verge of causing unprecedented damage to the oceans and the animals living in them.
There are clear signs already that humans are harming the oceans to a remarkable degree, the scientists found. Some ocean species are certainly overharvested, but even greater damage results from large-scale habitat loss, which is likely to accelerate as technology advances the human footprint, the scientists reported. Coral reefs, for example, have declined by 40 percent worldwide, partly as a result of climate-change-driven warming.
