One World Assignment – World Food
“How has Science affected the way the world’s population meets its dietary needs?”
In human history, up to around 10 thousand year ago, Earth’s human population remained at around 8 to 10 millions. Since then, Earth’s human population has grown, and reached its present level of approximately 6.4 billion (with annual growth rate of 1.4 percent). The more recent “explosive” growth causes serious overpopulation problems and environment problems. With increasing population, the demand for land and more resource increases. We should also notice the rate that we are employing our resources is not sustainable. It has been suggested that with rising population, it is possible that fossil fuel will run out in about 80 years. Food and resources are running out, yet the population is still increasing. This leads to the consequence of famine and malnutrition. Excellent introduction
Major hunger problems have occurred through out history, leaving millions of people dead or suffering the effects of hunger. Every day, around 24000 people die directly from hunger related to diseases unbelievable amount. According to UNDP data, 800 million to a billion people do not have access to enough food for life. Every year, over 15 million children die of hunger. Every 3.6 seconds some people die of hunger. Since you are read this information, at least 200 people have die of starvation and over 4 million will die this year. Good use of in-text references here Thanh.
The problem was highlighted by Thomas Malthus, a British economist in 1798. His theory emphasized the problem: Population will expand greater than food supplies and mass starvation would prevail. The fact that this has not happened is due primarily to the fact that Malthus greatly underestimated the ability of science and technology to improve agricultural productivity. Indeed the massive food shortages widely predicted to occur in Asia in the 1970s and 80s did not occur because of...
