Here is an explanation of their site's mission, taken from the Rescue Ocean Wildlife front page:
"Your free click generates donations from our sponsors. You may click once a day, every day. 100% of the donations raised go directly to Oceana to save our oceans through policy, advocacy and research. Oceana's scientists, lawyers and advocates work around the world to protect corals, make seafood safe, save sea turtles and more!"
You may remember the care2 social community from a recent post by the name of Stop Violence Against Women, which was another one of care2's projects. If you're interested in learning more about care2, see the linked page to read about the charity network more in-depth.
All it takes is a click to save the ocean -- so why haven't you done your duty yet?
