GOVERNMENTS worldwide take so long to realise the obvious witness the ozone layer, asbestos, pesticides that have made even the house sparrow a rare species. How long did they know any of the above were dangerous before informing the public?

Pollution is causing concern over polar bears in the Arctic.

A more mundane subject is washing up. I heard a programme claiming there is a carcinogen in this product surely there should be a warning on all canisters?

With all the chemical pollutants about today we do not need a tyrannical foreign power to use chemical warfare.

We are making an excellent job of poisoning our own people.
