With the recent problems in the Gulf of Mexico, it looks to me like oil spills are one of the major environmental concerns. We don't think about them as much as the others until they happen, but when they do happen they have an incredible lasting negative impact on the local environment. We really need to push our elected representatives to fight for alternative energy. The fat cats from big oil have lived high on the hog at our expensive long enough. It is time someone else gets wealthy helping save the earth rather than the current scum reaping massive profits destroying our planet.
