Thought for the Day

It is not just biodiversity losses we should be worrying about, it is the biomass. Think about it: biomass is related to carrying capacity. If England's farmlands are producing "x" tonnes of oilseed rape per acre, when years ago it was only "y" tonnes of weed-laden oats per acre, then it's the wildlife biomass that getting squeezed, however much artificial fertilizer is being added, and however much pesticide is being sprayed..

And if the populations of goats in Africa have gone up by 20 times in the past half century, then the wild antelope, and other wildlife will have decreased by a similar amount. It's what known as ecological balance. And no amount of research or education will change it.

Depressing but true.
