Beautiful marine species, beautifully captured. But each is at risk of extinction, according to the Treehugger slide show, “10 marine species on the brink of mass extinction due to ocean acidification.” According to author David DeFranza, “Adding carbon to the atmosphere contributes to global warming and climate change. Another less-discussed impact is ocean acidification — whereby carbon molecules diffuse into the ocean from the atmosphere, causing a steady rise in acidity.”

What can we do to make a difference? Check out this U.S. National Oceanic and Atmospheric Administration’s (NOAA’s) Ocean Acidification Program article, aptly titled “What Can We do about Ocean Acidification?“
