Global warming is a reality. You've probably noticed the difference between the arguments that took place a decade ago and now. The deniers have become fewer in number and less vocal. Having increasingly pumped carbon dioxide into the earth's atmosphere for over a century, the environmental cost is now becoming all too apparent.

We therefore find ourselves at a critical point in history. This is no longer a problem just for our grandchildren, but one that is bringing about global change right now. It will impact all of our lives to one degree or another.

Governments attempt to legislate, and some corporations are beginning to make genuine attempts to reduce their carbon emissions. But the problem is now too great to be solved without responsible individuals changing their behaviour in order to reduce environmental impact at all levels.
