No, it is not fair to deprive future generations of the free gifts of nature. That is why we should try to conserve natural resources and minimize environmental pollution. If not all resources may get exhausted and nothing will be left for future generations. If pollution continues at the present rate, many large cities may become uninhabitable in the near future. This will lead to a great crisis for future generations.
