Biology and the economy

Humanity has become nothing less than a plague on the earth. The Bible calls us to be stewards of this planet, A crowd scene in Hong Kongbut instead we are well on the way to wrecking it.

A BBC News item today reports that loss of habitat and species will soon begin to have a major impact on the world economy. There is so far little evidence that governments have grasped the size of the problems or their urgency, perhaps we are paralysed like a child who has thrown a ball and broken a window. Denial is easier than taking responsibility, owning up, and attempting to make amends. This is in addition to anthropogenic climate change and other issues (pollution, overuse of water resources, dwindling mineral stocks etc).

What we face is little short of catastrophe, but we are doing so little about it. We talk about more efficient agriculture, power generation from wind, sunshine, tides, and waves, recycling of waste, but we don't yet realise that we are merely tinkering. The greatest problem is rarely discussed because it is so difficult - there are simply far too many of us sharing the surface of our small planet.

One good sign is that greater affluence is resulting in falling birthrates in the developed world. In Europe, North America, Australasia, and the developed parts of Asia, birth rates are close to or even below replacement levels. But the less developed areas of Asia and Africa and to a lesser degreee South America still have burgeoning populations.

We must do what we can to reduce the world's population. If we do not - and quickly - the world will do the job for us through steadily increasing starvation and disease. This is likely to be widespread through the developed world as well as less privileged regions.
