Jim Al-Khalili talks to environmental scientist John Lawton about making space for nature. A keen birdwatcher from the age of 7, John describes his studies of birds, dragonflies and bracken and his groundbreaking experiments in the Ecotron, essentially a box full of nature. For the last few decades John has advised successive governments on a host of environmental issues such as GM crops, road traffic pollution and nature conservation. His latest report Making Space for Nature was turned into policy remarkably fast but, he says, it isn't always easy to get governments to listen to environmental advice based on science.
