About Beyond Malthus: Nineteen Dimensions of the Population Challenge
This book is a great book that brings to light some of the problems the world currently faces. During the last half century the world population has more then doubled, climbing from 2.5 billion in 1950 to 5.9 billion in 1998. Malthus foresaw food shortages and famine because of the massive increase in population growth. The rise in the worldwide population accompanied with consumption is pushing the planets beyond its natural limits.Throughout this book nineteen main environmental issues are addressed. I decided to focus on three main topics, that I feel are the most important; they are fresh water, biodiversity, and waste. Evidence of water stress is seen all over the world. According to Brown there will be scarcely one fourth as much fresh water per person in 2050 as there was in 1950. Worldwide, some 70 percent of the water pumped from underground wells or diverted from rivers is used for irragation, 20 percent is used for industrial purposes, and 10 percent for residental use. As population keeps growing more water is being diverted to urban areas, this is the same water that is usually used for irrigation. The main point being addressed is that the shortage of water means the decrease in food being produced.The next topic covered in the book is biodiversity. As human populations keep growing other species are affected, some to the point of extinction. According to Brown the major source of species loss is habitat alteration, invasion by exotic species, pollution, and over hunting. As populations keep growing more people are forced into undeveloped areas that our host to many different species. This is where over hunting comes into play. People have to eat, or make a living selling skins or other animal parts. This problem is the greatest in underdeveloped countries where there are little or no conservation laws.The last topic addressed is waste control. With a constant increase in population, the flow of waste products into landfills and waterways is increasing. Municipal waste is a major source of this problem. On average 824 million tons of waste are produced in developing countries each year. With an increase in population growth this number will rise to 1.4 billion in 2050. It is suggested that government agencies have to step in order to regulate this problem. Finding new ways to dispose of waste have to be discovered in order for the world to live with less disease.Overall I felt this book was very informative about some of the problems of the world. I wish there were more solutions for what needs to be done in order to solve these problems. I think more education needs to be conducted in developing countries to reduce birth rates. According to Brown the current fertility rate in Pakistan is six children per woman and nearly seven in Ethiopia. These numbers have to be lowered in order for these countries to sustain a reasonable standard of living.
