You shouldnt feel bad. Your country is most likely not actually polluting the world. Most 1st world countries have pretty much cut out pollution. You get the odd oil spill but thats not really a big deal in the Grand sceme of things because of how rare they are and how much effort goes into clean ups.

Most of the pollution you see comes from other countries.
