WE are regularly told that Britain is doing all it can towards reducing pollution in an attempt to combat global warming.

Even if this is not the correct prognosis, we can still save energy and money by many of the procedures suggested.

However, since scientists are prone to changing theories as new information develops or not, I am still doubtful that their predictions are correct.

To predict in the future of what the climate will be in even 2030 is making a few insupportable assumptions. How can there be any knowledge of what will appear on the scene over the next few years?

We should remember these facts. Britain has about 56 million people - what sort of effect will their efforts have in the world where the total population of India, China, Russia, Indonesia and the USA is much more than 1,000 million?

None of these countries, some still developing, is making as much, if any, effort to reduce pollution as Britain.

The war in Iraq, fighting in Israel and many other places probably produces enough pollution to wipe out anything we have reduced in this country.
