I didn't see dinosaurs, you didn't see polar bears?

Dear Future Generates,

You've all probably heard of dinosaurs, the almost mythical creatures that roamed the earth millions and billions of years ago, and we are still finding out more and more about them. Do you ever think about how cool it would have been to see a dinosaur? Or maybe not if you've seen Jurassic Park... but here is another almost mythical creature you probably have only heard stories about. I'll tell you about them, they live in the north pole, killing animals and living on these things called icebergs.

You've probably haven't heard of those either. They are large sheets of ice that at one point covered the earth, and now aren't around anymore due to us. The generations before me and my generations have taken that away from you, with our awful pollutants and killing of the environment. We never took care of anything, such as something as simple as recycling or throwing away our trash or not using plastic or helping clean up all areas. We are barbarians that do not think of the earth's future, but instead the future of money we can try to make.

We place everything in your hands, the future is dependent on you, we trust you to not only fix our mistakes, but also to reverse them.
