Dear Dr. Brown:
We'd like to express our opinion about global warming.
Let's say first that we need your help. We need you to create an invention for stopping global warming, because we think that is wrong that people create campaigns for stopping it but, at the end, don't do anything and go anywhere. We have to prevent things like: melting poles, the tide going up, the greenhouse effect, species starting to become extinct, and so much more. We think this way because we realized that we made a mistake and we want to change the people's thinking way, and stop it at once.
Please think about it and then call us back. Thank you.
