We are seeing "Global Climate Change" all around us. Just the other day I found a Hyperolius marmorathus (Painted Reed Frog) in the nursery, these colourful frogs are (or at least were) restricted to the humid coastal zones of South Africa, Mozambique and Northern Zim., this is way out of its normal distribution and proof that climate has changed. Perhaps Professor Lovelock is a "doom and gloom" crazy scientist, but perhaps global birth restrictions would, in time, lessen the demand for fossil fuels and relieve pressures on natural resources, especially in African countries. To conclude, the earth is a chemical reaction, we can neither add nor destroy matter, simply alter its form. If we disturb the balance a opposite and equally powerful reaction will occur to restore the balance, so we have burned millions of tons of coal, oil, gas etc. and releases fast quantities of CO2 into the atmosphere effectively disturbing the balance. Global Warming is the opposite and equally powerful reaction that will, in time, restore the balance... if our bulbs will survive remains to be seen! Pieter, from a exceptionally wet and cold March.
