Growing populations, falling energy sources and food shortages will create the “perfect storm” by 2030, the UK’s chief scientist Professor John Beddington has said.
The demand for resources will create a crisis with dire consequences, Prof Beddington predicts.
Demand for food and energy will jump 50 per cent by 2030 and for fresh water by 30 per cent, as the global population tops 8.3 billion. Climate change will exacerbate matters in unpredictable ways.
“There’s not going to be a complete collapse, but things will start getting really worrying if we don’t tackle these problems. My main concern is what will happen internationally, there will be food and water shortages,” he said.
He said we need more disease-resistant and pest-resistant plants and better practices, better harvesting procedures. Prof Beddington said the “storm” would create war, unrest and mass migration.
Growing populations and success in alleviating poverty in the Third World will create huge demand for food and water in the next two decades with climate change depleting resources.
He said food reserves are at a 50-year low but the world requires 50 per cent more energy, food and water by 2030.
The United Nations Environment Program predicts widespread water shortages across Africa, Europe and Asia by 2025. The amount of fresh water available per head of the population is expected to decline sharply in that time.
Hello. Great job. I did not expect this on a Wednesday. This is a great story. Thanks!
