The G20 circus is in town. Gordon Brown revelling and protestors protesting. The aims are laudable. Stimulate respective economies with large amounts of cash, target the poor people who will spend money quickly and so stimulate the economy, spend on infrastructure, use this opportunity to fund green projects to improve the environment and reject all forms of protectionism. Sadly all this is just gas and will not work and we will be here again in a few years. The reason is that, as usual, truth has been left out. Perhaps the most important topic should have been how to stop the growth of poor population in the world. The sad fact is that the poor everywhere are breeding without restraint with politicians choosing to avoid talking about it in case they are accused of being antipoor. More people means cutting down forests for agriculture. More fossil fuel for cooking, travelling and energy thus increasing CO2 production. More houses cut down agricultural land for food production leading migration from villages to cities and from poor to rich countries. Couple of days back hundreds drowned of the coast of Libya. Thai police put Burmese immigrants in a boat and pushed it out to sea. The US is building a fence along its border with Mexico. Rio mayor is constructing a wall to stop extension of slums up the hillside. How long before the rich countries use gunboats to stop migrants from poor countries. How long before the rich barricade themselves in walled cities protected with cannons to keep out the hungry hordes? Help the poor, sure, but it should not be seen as a present for breeding. The more the children the more the aid. So encouraging. Perhaps the G20 should have a lecture on our sister planet Venus.
