The Declaration states that changes in the pH levels of the oceans are occurring 100 times faster than they would naturally and we've been warned that unless there are dramatic cuts in our CO2 emissions there could be severe damage to our oceans.

Researchers claim that if we don't cut down on our emissions, most regions of the ocean will become inhospitable to coral reefs by 2050, leading to substantial decline of fish stocks and threatening food for millions of people. Our ocean will, in fact, be close to death.

If that isn't a wake-up call, I don't know what is.

For years now we've been in debate about whether humans are indeed responsible for climate change, or whether it's purely a natural occurrence; after all, the earth has been going through phases for years. Why is this any different?

If we humans are indeed responsible for climate change (which is most certainly possible, despite the huge divide between scientists and campaigners), then it brings us to the classic Easter Island theory.

The very basics: humans arrive on a peaceful, plentiful island. Resources are plush, everyone makes the most of it by making hundreds and thousands of stone heads and using up all the resources until they begin to run out. The trees are gone, there's hardly any food, the rest they fight over, and in the end they leave the island dead and deserted. The stone heads are the only thing that remains.

It's a basic human flaw and we're seeing this story repeated all over the world, in many similiar scenarios; from power-hungry dictators to countries fighting over resources and weapons.

Let's hope we can do something about it before it's too late.
