Answer:
Hello Editor,
I am writing to you about a very concerning matter of garbage. I wish you could take into consideration that garbage is polluting our world and air. It is causing problems not just on air but in the sea too, as garbage gets thrown into the blue oceans that will become black if we don't do something. Animals are eating plastic bags and plastic forks. This is a big red flag to the higines of our world which is about to break because of the amount of garbage.
Sincerely,
(your name)
