The disaster in the Gulf will have lasting effects on the environment for many years to come. Here is a link to the Official Response site on the Gulf clean-up. The images of oiled birds and turtles have me tossing and turning every night, and new and disturbing aspects of the spill are brought to light daily. Below is a link to a YouTube video made by a birder in the Gulf, which shows some of the unintended negative effects of the response on sensitive species. I think it highlights just how unprepared BP and the agencies were to handle a disaster of this magnitude.
There is an effort to raise awareness and funding for the continued recovery effort. It's important that this be done because the general public has a woefully short attention span for disasters - think Katrina and Haiti. This jeweler has a Gulf collection - it's my understanding that some of the proceeds go towards the clean-up effort.
This link helps to give you a visual understanding of the size of area the spill encompasses. Pretty frightening in these terms.
