sir david onside for lights out london

As arguably the world's most famous naturalist, it's wonderful news that Sir David Attenborough is backing Lights Out London. The renowned green campaigner has been discussing the significance of the event to our natural environment. "Plants have caused the rainforest to be called "the world's pharmacy" because of their wealth of natural medicines, and they include literally thousands of undiscovered species," he said. "Who can put a value on the loss of animal and plant species? Or potential cures for cancer or other diseases? Those would be good reasons to ring alarm bells on their own."

Recognising the fact that small differences can effect real change Sir David went on to explain the importance of individual action. "I am not only thinking of the survival of animals and plants. I'm thinking about humans too," he said. "Rainforests are worth much, much more to the human race left standing, helping to keep the planet cool, than they are cut down for timber or burnt to clear the land for cattle ranching. We simply have to act".
