If we were to succeed in making low immission, low noise vehicles, then it would no longer matter if a person lived near a six lane freeway because the air would be sweet and the noise unnoticable. If we created renewable and low pollution sources of power for our homes and industries, then it would not matter where we built our power plants because they would not spew filth into the skies. We could leave the lights on at night and damage only our wallets.
Reducing pollution will improve the lives of all, regardless of what the Earth's climate is doing. Many make the mistake of thinking that they and their environment are discreet entities, but they are missing a very important relationship. The air we breathe, the water we drink, and the food we eat are all part of who we are. Keeping them as clean and unsullied as possible is in everyone's best interest.
