There are many threats to global food supplies. Explain the problem, identity possible solutions, and assess the implications of implementing these solutions.
Because of the increasing world population and the growth of the environmental problems such as global warming and acid rain, global food supplies meet great challenges to feed so many people especially those in economically richer areas wasting foods. A series of problems following food supply shortage like the competition of land, water and energy are also existed. This essay will look into these problems, provide some possible solutions and evaluate them.
World population is a constant problem since 1900(Horiuchi, 1992) and it still grows at least in the next 40 years. There is a forecast that there will be 9.2 billion people in the world of 2050 predicted by the Royal Society (Black, 2010). How to prevent people from starving is a much more serious issue than the global financial crisis. The climate change caused by human activities is also damaging the food supply system. Environmental problems such as global warming or acid rain are changing the land and water for food production, making some of them not suitable to produce food.
The global food supply shortage is not the only problem happening now, there are many other ones. A larger population means people need more space to live and more water to drink, then ecosystem is disturbed by human beings in order to survive. Beneficial species are decreased, while harmful insects and animals spreading diseases are increasing, making chemical and genetic pollutions also increased. How to increase the yield production with less land, water and energy is really a serious challenge for the next generation.
Possible ways to solve those problems are globally discussed, such as finding more arable lands as the traditional way, using science like biotechnology, genetic technology to increase yields and...
