The world is less 40 years away from a food shortage that will have severe consequences for people and governments. That could become as politically threatening by 2050 as energy problems are today. According to Dr. Davies, population will increase to 9 billion people in thirty years, having to increase the food supply a 70% to meet demand. Despite he thinks that biotechnology and genetics will play a key factor to determine our ability to produce that amount of food, more efficient technologies and crops will need to be developed to address this challenge. Increase food demand comes at a time when the world is investing less in agricultural research, increasing the risk of social and political disorder that could lead to civil wars and terrorism.

Climate change could cause a two percent drop each decade of this century. Big countries like Australia, Russia, Canada, China and the United States have suffered big floods and droughts that lead to huge losses. The environment could also get damaged since reducing water levels will become scarcer from overpopulation and its augmented use in agriculture. The only region in the world that will be able to feed itself and others in South America, while countries like India will only meet the 59 percent of its demand by 2030.

More effective agricultural production, better ways to store food and biologically diverse can lead to less vulnerable global changes. Strategies for the future must be discussed and new systems of land, water, energy and biological resources must be applied.
