Помогите! Необходимо написать письмо:You have received a letter from your English-speaking

Hi, Max!
Glad to hear  from you!You wrote that you had had an ecology class recently. Cool! You won't believe but we had the same lesson two days ago and we discussed the same ecological problems and many others. The topics we spoke about during our discussions were littering, air pollution, water pollution, endangered species, destruction of natural resources and others. We decided that we had to change the environment for the better. We must turn to our government, scientists, all people to call them to do the best for the prevention of pollution of water and air!   And of course, we must save drinking water, not to let it just flow into nowhere. It can be done even by a child. Everybody must be taught to close the faucet with drinking water when it is not needed. Only together we will save our planet and live on it happily.
As for your latest news, it's cool that your sister is going to marry soon.
When will her wedding take place?
Who will be her husband?
Where will they go after their wedding?
Best wishes.
Write soon,
Nick
