our helth depend of the nature because if nature will be pollution our helth will be in danger . we must protect nature because is very expensive we mustnt cut the tree because the tree clean air but even if we cut a tree we must plant 10 tree instead the one tree . we mustnt use the toxic fertilizer when we plant a tree or vegetables.also we mustnt pullutionwater with a trash because we will drink the dirty water . i thank the nature is wonderful and we doesnt destry it !!!
