North America – From Seals and Sharks to Central Park

We are only now beginning to appreciate the effect of human impact on North America’s complex ecosystems.

The most difficult problems to tackle are those that are hard to see and quantify, like climate change which is affecting humans and wildlife. Changes are happening all around us. Glaciers are melting, dolphins and whales have to survive in increasingly polluted oceans. If we are to understand the consequences of our actions, and to repair ecosystems, we need people like you to help Earthwatch scientists in the field.
