I have a friend who is always trying to save money by using public transportation instead of private cars.

He has even started to blackball any company that doesn"t support environmentally friendly practices, and he has even been blacklisted by some companies for his efforts. He says that it is worth it to make a difference in the world, even if it means being ostracized by some people. I admire his dedication and I hope that one day we will all be able to make a difference in the world by taking care of our planet.
