Deforestation

Not quite sure I understand what you are asking. You might restate the question.

Because people only think that it won't affect much only by my doing, there are so many people who are cutting the trees for their profit, then it won't make much difference if I do the same. Whereas, they forgot to think about if everyone used to think like this then what would be the future.
People only remember that plants can grow again but they don't recall that it took many years for a plant to become a tree. People don't give much importance to this, they think I planted another tree to replace it but the fact is trees cannot be replaced at the same pace as they are cut.
