Optimum Population Trust

A quote here from the new OPT newsletter.

Lovelock Becomes Patron
Dr. James Lovelock, the scientist responsible for the Gaia theory, is the latest leading green thinker to become an OPT patron. Dr. Lovelock, who has warned that climate change will cause mass human mortality over the coming century, reducing the world population total to as little as half a billion, said that population growth and climate change were “two sides of the same coin” and called on environmentalists to “recognise the truth and speak out” on the link between rising human numbers and global warming. OPT is delighted to have his support.
