Plants inspire us to breathe․ Without plants we would not have vegetables, fruits and other useful things․ We could not bake bread because we need flour to make dough, and flour is made from grain. Water should not be polluted because a person can live without water for 2-3 days․ We must not pollute nature in order to live in peace․ There is a dumb trash can․ Take care of nature and do not pollute the Earth․
