help me to correct mistakes in my composition,please

Dear George,
I was glad to receive your letter! I'm sorry I haven't answered earlier ,but I was really busy with my school.
Well, I think that everyone should know about ecological conditions of their cities, countries and the planet as a whole and how it could be improved so ,in my opinion, ecology should be a school subject.Also you asked me about my classmates. Most of them are friendly and can help you anytime. What about Eco project, I would like to join the project to rid the planet of rubbish.
By the way, when are you going to show your presentation? Why did you choose the project about air pollution? Are you interested in other project
Anyhow, I'd better move at once.. Mum asked me to help her with the housework.Hope to hear from you soon!
All my love,
Nastya.

I am also doing eco friendly business.
