If we unbalance nature, humankind will suffer. Furthermore, we must consider future generations: a clean environment is a human right like any other. It is therefore part of our responsibility toward others to ensure that the world we pass on is as healthy as, if not healthier than, we found it. This is not quite such a difficult proposition as it might sound. For although there is a limit to what we as individuals can do, there is no limit to what a universal response might achieve. It is up to us as individuals to do what we can, however little that may be. Just because switching off the light on leaving the room seems inconsequential, it does not mean we shouldn’t do it.
