A petition against DHMO was passed round at one of the big climate conferences many years ago. They pointed out that surprisingly small amounts of DHMO can kill. It was used in the Nazi death camps of the 1940s. It can be brought in to your country by planes and boats. If you get some on the surface of, say, fruit no amount of washing will remove every last trace. Children can come across DHMO while playing. In its gaseous form it can cause severe burns and it is a major component of acid rain.

A large number of conference attendees signed the petition!
