Помогите написать письмо другу на тему экология

Hello, Peter! I was glad to receive your letter! Now I am very busy at school. I write a project about environmental problems in our country. It is a very important problem. Our nature is in danger. Soil, water and air are contaminated with toxic wastes. Factories pollute our rivers and lakes. The increasing number of cars in cities has led to the growth of harmful gases in the atmosphere. There is much litter everywhere. Our parks and forests are full of rubbish. The result of it is ozone holes and the greenhouse effect, and the health of people. I think that the Earth is our home and we should protect it. What do you think about it? What can we do to change the situation? Sorry. I have to go now.Write me soon! Bye!
