Green awareness

Another from the world of science to be honoured is Dr James Lovelock. He becomes a Companion of Honour.

The researcher, author and Fellow of the Royal Society played a crucial role in raising environmental awareness in the late 20th Century.

He is best known for his Gaia theory, which views the Earth as a self-regulating "living" system rather than a balance of competing physical, chemical and biological interests.

Dr Lovelock contends that this system works to maintain the conditions that are suitable for life - organisms not only adapt to the environment, but change it as well.

Dr Lovelock's ideas, expounded in several books, have heavily influenced the green movement, although he is a supporter of nuclear power.

As a research scientist, he developed techniques for monitoring gases in the atmosphere.
