More evidence that climate change is destroying our coral reefs, an iconic symbol of ocean diversity and beauty, and the biggest sign of life on Earth (since they're visible from space). The Australian Institute of Marine Science (AIMS) says coral growth in the Great Barrier Reef "is at its slowest rate in 400 years and could stop altogether by 2050." The study found that the absorption of atmospheric carbon is likely causing as much damage as rising temperatures. Porites -- the type of coral sampled in the study -- produce layers of new growth each year, so scientists can study environmental changes by looking at skeletons, much like reading tree rings. The Australian findings are not unique. We reported on research in the U.S. that discovered higher levels of atmospheric carbon has led to a 30% increase in ocean acidity over the last 200 years -- ten times faster than climate models predicted. The increased acidity is corroding the calcium carbonate shells and skeletons of many marine species, wreaking havoc on biological communities. "These organisms are central to the formation and function of ecosystems and food webs," the AIMS researchers say, "and precipitous changes in the biodiversity and productivity of the world's oceans may be imminent."

It's true what our moms said...we are what we eat. In fact, it's truer than they thought. What I eat doesn't just affect me anymore, it affects all of us.
Unfortunately, the story of food can sometimes be complicated. But envirovores help each other out...which is why this blog will be bringing you news, tips, and information about food and the environment every step of the way.
