I refer to 'Priorities' D E Margrett (Letters, May 5). I do not exaggerate Mr Margrett, your figures, on population density, are wrong!

My figures refer exclusively to England and China, and I wrote in August 2003 "our population density is 379 people per square kilometre. China has a population density of 117 people per square kilometre."

Current data from the internet gives figures of 383 people per square kilometre for England (www.statistics.gov.uk) and 133 people per square kilometre for China (www. photius.com).

We are "three times more densely populated than China!"

Mr Margrett is wrong in saying "Our lives are too brief for us to know much about our environment."

Ice Core data can go back for around half a million years, and can give us climate profiles, over that vast period of time. In addition "Dendrochronology" - the science of tree rings - can go back as far as the last Ice Age, and can give us climate profiles for around the last 10,000 years.

As regards Mr Margarett's, "The provision of homes for those who need them is more important than the view from this correspondent's window," perhaps Mr Margrett should ask himself how much longer we can go on concreting over England?

We don't own the land.

Our generation is supposed to keep it in trust for future generations.
