Is the Gaia Theory possible?
First it must be explained what the theory is, and the best way to do this is to link you to the Wikipedia listing. James Lovelock, the author has proposed that the Earth is a self-regulating system.Using this hypothesis it should be possible to identify what changes are already under way due to the actions the human race has made to the planets life support systems.
We are already experiencing a change in the local climate in many parts of the world, and this trend is expected to continue. Locally we had a storm that was rated the worse in a 100 years and flooded houses for the first time ever, took out the power and trapped us in a restaurant for 3 hours due to the water.
Other parts of the world are experiencing uncommon draughts and wild fires. Nature is stressed and confused and is likely to react strongly over the next few years.
Or is this all just normal and has nothing to do with the global population and all the consumption of fossil fuels? How are you going to explain the climate changes to your grand children?
