Conservation International has been protecting our earth creatures for the last two decades. They operate on the simple principal that when human beings live harmoniously with nature instead of exploiting it, both will thrive. Their website lists a shocking statistic that I wasn't aware of, every twenty seconds one species becomes extinct!! That's a pace a thousand times faster than has ever been seen during Earth's history! How can this be happening? Climate change and habitat destruction are to blame. Conservation International is on the front line of the battle to save creatures that are in peril. They conducted the first ever Global Amphibian Assessment, a study which provided vital information on the state of every amphibian species on earth! They are currently doing similar groundbreaking research on sharks. This is one of the hardest working and most exceptional charities I've read about, visit their fabulous website (tons of amazing video and pictures) to sign petitions and see the many ways you can donate.
