Nature is our mother.because we live cut off from her,we get sick. Some of us are only cement,metal,and hard things like that. Our fingers do not have a chnce to touch the soil; we don't grow lettuce anymore. Because we are so distant from our mother warth,we become sick. Thats is why we need to go out from time to time and be in nature. It is very importan. We and our children should be in touch again with mother earrh. In many cities, we cannot see trees-the colr green is entirely absent from our view
