But Tom, we’ve always had these problems. The climate has changed dramatically through the centuries, with ice ages, volcanoes, canyons being carved by rivers that are now dry riverbeds, jungles disappearing. Some species that were almost extinct have made comebacks with the help of conservation efforts. There’s much much more to be done, but I believe more young people than ever before are environmentally aware and concerned. Maybe I’m an optimist, and I do understand your point, but I tend to take a hopeful view in light of the fact that there are so many people who care and are willing to do something about it.
