Climate Change affects the food production

I would like to write good news ever. But when you analyze the human behavior sometimes this is not possible; specially, when you consider the human being attitude regarding the natural resources conservation.
Man is a depredator of nature. He has a trend to destroy the wealth given by God to humanity.
Two hundred ten years ago, in 1798, a brilliant priest and economist, Thomas Robert Malthus, (1766-1834), in his Essay on the Principle of Population said that “the power of population is indefinitely greater than the power in the earth to produce subsistence for man.”
Malthus could not imagine that two centuries after the Climate Change would confirm his theory. Malthus did not know the Climate Change. The Pre Industrial civilization ---the Second Industrial Revolution began at the middle of the XIX century--- was a green and not contaminated world.
But now, almost 210 years after, the facts are confirming that the possibility of producing food for feeding the growing world population is every day less. The Global Warming is affecting the sources of water worldwide. Without water the agriculture development is not possible and the true is that every day the availability of this resource is diminishing in the world.
The World Bank in its World Development Report 2010, Development and Climate Change, warns that “the developing countries would be the most vulnerable by the Climate Change, with permanent reductions in GDP of 4 to 5 per cent for Africa and South Asia.” In the Foreword of the same Report, the President of the Bank, Robert Zoellick assures that “it is crucial that countries reach a Climate Agreement in December in Copenhagen that integrates development needs with climate actions.”
To adopt the measures for resolve the problem of the Climate Change and its consequences is something essential to guarantee the world surviving especially, the future of our sons, grandsons and the next generations.
