Dear son or daughter,
The world we are in today is real nice, even though we are fighting to stop climate change. The conditions will get worse, but since we cannot feel the effects immediately, it is hard to get people to help out. Even though our future seems grim to environmental majors like myself, I have full belief that your life will be full of the same joys as mine. I believe we will figure out this complex problem, because there are too many people who do care for our planet. If this is not the case though, I want to say I am sorry for the tremendous amount I have contributed to the problem. I promise from here on forward that I will do the best I can to take care of the planet.
