Every day I am more convinced that we desperately need a supranational legislative body that can effectively set and enforce laws. There is the UN, but it is too bound by the interests of a few powerful countries. The world is getting too small to allow these types of environmental disasters to be handled by the very people responsible for letting them happen. God, it is so frustrating... Those who can make you believe absurdities can make you commit atrocities. -Voltaire
One organization which does some enforcing protection of the environment is Sea Shepherd. But I hardly know other examples.
