Carte Blanche's 'Cool Earth' DVD offers a nifty package of episodes on climate change. Informative, varied and interesting, it provides a fairly comprehensive overview of the challenges presented by global warming and some of the ways in which you, as an individual, can help combat the problem.

In total, there are six episodes on the DVD. Each episode takes a different angle, but unlike other documentaries on global warming, this one has a specifically South African slant.

The first episode 'Africa Burning' looks at the effects of veld fires on climate change and the increased prevalence of fires as a result of climate change. This is followed by a more practical episode on 'Earthworm Farming', which explains how it works and what you need to set up your own earthworm composting system.

The next two episodes focus more on the technical aspects of global warming and global dimming, explaining in easily understandable terms the effects that these two phenomena have on climate change and the politics around worldwide efforts to reduce carbon emissions.

'Hollywood Going Green' looks at the current green trend in Hollywood, focusing on stars that are environmentally-friendly and celebrity-endorsed documentaries such as 'An Inconvenient Truth' and 'The 11th Hour'.

The DVD wraps up the series with an episode on timber plantations in South Africa, which some environmentalist argue do more harm than good despite their carbon-converting capabilities.

Although the DVD doesn't offer a single integrated take on climate change, its coverage is quite comprehensive and the concise episodes offer more flexible viewing. Avid 'Carte Blanche' viewers will have seen it all before, however the collection is ideal for those who are passionate about the environment or those who would like to educate others about the effects of climate change.
