The correct answer to this open question is the following.
This would be my letter.
Hi dear Pete,
How are you?
I am doing good. A little bit worried about the way people exploit our natural resources and raw materials, affecting the environment.
Remember the beautiful river where we used to play when we were children? Those funny summer days swimming in the river.
Well, today's children can't do that often because industries have over-exploited the water from the river.
And the worst thing is that nobody cares. Local authorities do not take any action. Citizens seem uninterested.
But you know what the problem is? By the time we do not have fresh water to drink, then everything will be chaos. But why wait until that happens.
Let me tell you that I have been thinking about forming a group, a non-governmental group with my friends at school.
Yes, I pretend to use the college newspaper and radio station to expose this situation because the lack of water in the river has affected the trees, the plants, and the farmers of the region that do not have enough water to produce their crops.
I am writing you to know your opinion. Would you be interested in joining this project and promote it in your school?
Please, Pete, let me know soon.
Send you big hugs!
Regards,
