I'm a student from 907. I write this letter to you because I found that there are more and more plastic bags at
school and we all know that it is not good for the Earth at all.
Plastic bags were made of “polyethylene” which is made out of petroleum. Petroleum as we know is a limited
natural resource. Since most of the plastic bags we use are broken into small pieces and will never decompose into
the earth! The plastic bags left as a garbage would affect the wild life. Stray dogs would eat them with the food. Sea
animals would mistake them to be jellyfish and eat them. Even the sea birds and turtles also eat the pieces. The plants
would grow on such land and the animals would feed on such plants. And we are on the food chain, too.
It's very easy to say no to plastic bags. Keep a bag with you. Don't ask for a plastic bag if you don't need one.
You can always carry the things by hand. Whenever you want to get a plastic bag, think of the fact that it would be
for centuries on the earth.
I hope everyone at school can say no to plastic bags. Can I have the chance to speak in front of all the students?
