What nature need from us and what we from nature ?

At dawn my friend came my home and ask me for money. But that time I don't have. Him badly need of, I decided to follow trailer machine. When I withdraw
Money , I get one option in machine -Are you need of slip of your withdraw? And below another line was mentioned 'plz say no to save the trees. I choose NO. After few steps a saw many newspapers were in dustbin box. I don't know why but I think those person who through them , don't know how they prepare. We cut millions of tree to ready papers. We can reuse them but due to cheap cost we don't reuse . The whole community doesn't value of cheap things and it can be man also.
