Dear Andrew,
Thank you for your letter. I really do appreciate your writing to me.
That is such a good thing that you're helping our nature survive the harshness and recklessness of the human attitude to it. I should think it to be your great achievement. Could you tell me more about the campaign in which you and your fellow students are involved?
As for your questions, there are no campaigns of sustaining the environment even on the school grounds in here. None at all, believe it or not! However, I am really concerned about the state of our environment, so I always try to make my personal contribution to saving the nature: I do not litter in the street, neither am I being negligent towards others' letting - I always condemn people who do so and encourage them to be more thoughtful. As you might deduce, there is no name for my improvised campaign, because there is only me enrolled in it.
Does your campaign receive state funding or is it just being crowd sourced? How many volunteers take part in it?
I'm looking forward to your soonest reply.
Yours sincerely,
[your name]
