On joining the Optimum Population Trust, Sir David said growth in human numbers was “frightening”.
Sir David has been increasingly vocal about the need to reduce the number of people on Earth to protect wildlife.
The Trust, which accuses governments and green groups of observing a taboo on the topic, say they are delighted to have Sir David as a patron.
In a statement issued by the Optimum Population Trust he is quoted as saying: “I’ve never seen a problem that wouldn’t be easier to solve with fewer people, or harder, and ultimately impossible, with more.”
