Threats to global food supplies
In the twenty-first century, with the rapid development of technology, living conditions have improved increasingly. However, the problem of food security has not yet been addressed, especially in some poorer countries. This essay will analyze the reasons, provide the solution, and evaluate the results to the global food supply problem.
There could be two main reasons. The first one is the gap between the food supply and the food to feed the growth of population. According to the Royal Society, it will get to the peak of 9 billion by 2050 (text 5a, line 9). To solve this problem, measures should be taken immediately.
One effective way is to raise the food yield to meet the growing demand. This can be done by using the advanced technology. Recently, the genetically modified crops, namely crops involve relatively simple manipulations (text 5d, lines 37-39), has popularized in many countries. This biotechnology may increase the food field, but also raise the issue of whether it is sustainable.
Another measure is to reduce the food waste. As for the developed countries, raising food prices and advocating balanced diet are effective methods for refusing food waste. Given the poor living conditions of the developing countries, governments should invest in infrastructure so as to reduce the food distribution loss. According to FAO, about one-third of cereal production is fed to animal in worldwide (text 5d, line 139-140). This is to say amounts of food have wasted. If these cereals could be changed into food supplying to the hunger, the problem might be solved in some extent.
Climate change is also a significant problem that has created regional differences in food supply. Therefore, in those countries lacking of good farming conditions, food is more valuable. Trade globalization, through interchanging advantage products between developed and developing countries, could achieve the aim of resource sharing. But, “the...
