Pollution 1: What do you think about pollution of cities, lands, sea and air?
Some people don't care or pretend that they don't think pollution is a problem. These are future-eaters.

Other more thoughtful folks know there's a problem, both with poisonous pollution and with greenhouse gases like carbon dioxide. (Have you seen my guides about Pollution and Energy?) Many try hard to do what they can about it by using cars less, turning down the heating or air conditioning and so on. Many would do more if they knew other people were too. How can we make this happen?
