1) The lvl of pollution is big in Russia, and this is a fault of people.2) I think that the guard of environmental is the most serious scheme, because flowers, animals, oceans etc. are destroying now. Everything begins with us, so we must keep the nature so long as we can. 3) Every tree depends on people. But I think that nobody have such skills, how a plain human has. Everybody must lower the level of pollution and then everything would be OK.
