I remember the first Earth day. I was in high school and we had just printed another edition of our underground newspaper and were selling it at school. Later we went to a local park where we heard speeches on Earth day. I am vague about that part.
Now we recycle our cans and bottles and buy cars, for the most part that get better gas mileage than our grandparents got in the fifties. We've done the easy stuff now. The question will be if we as a people will be willing to sacrifice our prosperous life styles for the environment. Well at least we used to have prosperous life styles.
