Zoologist Bob Paine has conducted experiments on a small island off the Washington coast for over 30 years in one of the longest ongoing studies of a single area by the same scientist. His experiment on the connection between starfish and mussels has resulted in one of the most important principles of modern ecology, known as "keystone species". Paine showed that certain species are critically important to the balance of particular ecosystems. The loss of a keystone species can have a devastating impact on that ecosystem's biodiversity. Humans impact the biodiversity of the world more than any other creature. We are the ultimate keystone species. Thus we have a larger responsibility towards the world around us.
