The powerful before-and-after photographs below were shared as evidence of ocean acidification at the 2012 International Coral Reef Symposium in Australia. Please help spread awareness about ocean acidification by pinning these before-and-after photos and starting the conversation about ocean conservation. #OceanAcidification

The Arctic tundra supports a variety of animal species, including Arctic foxes, polar bears, gray wolves, caribou, snow geese and musk-oxen.

Today, however, as the permafrost melts and dead plant material decomposes and releases CO2, the tundra has flipped from a carbon sink to a carbon contributor.
