A look at some of the options we have of reducing our carbon footprint.

In a recent poll of 530 climatologists in 27 countries over a fifth of interviewees rejected the notion that a substantial part of the current global warming trend, which might see temperatures rise by a degree or two, is caused by man's industrial activities.

Climate change - fact or fiction? In the past dozen years or so a major controversy has developed through out the world about changes that are supposedly taking place with the earth's climate.

As a consequence of global warming, sea levels are also expected to increase by 0.76 - 1.58 meters in the next century, which could cause flooding in key cities around the world such as New York.

For one example, it is dubious whether using fertilisers – the production of which causes CO2 emissions – on crops whose only purpose is to be fed to cows for milk is really a sensible act, and organic milk is now standard in our supermarkets.

Is the earth doomed to massive flooding or is it just a load of hot air?

The recent conference on global deforestation held in Sydney co hosted by the Australian Ministers for Environment and Foreign Affairs drew a crowd of ministers, officials from all over the world and international development agencies.
