Today, the world's population is over 7 billion, about four times what is was a century ago. At the same time, many people are enjoying a much higher standard of living than did their great-grandparents. A perennial debate concerns whether this growth in population and living standards can continue in the future. Many commentators that natural resources will eventually limit how much the world's economies grow. At first, this argument might seem hard to ignore. If the world has only a fixed supply of non-renewable natural resources, how can population, production and living standards continue to grow over time? Eventually, won't supplies of oil and minerals start to run out? When these shortages start occur, won't they stop economic growth and perhaps, even force standards to fall? Despite the apparent appeal of such argument, most economics are less concerned about such limits to growth than one might guess. They argue that technological progress often yields ways to avoid these limits. If we compare the economy today to the economy of the past, we see various ways in which the use of natural recourses has improved. Modern cars have better to heat and cool them. More efficient oil rigs waste less oil in the process of extraction. Recycling allows some non-renewable resources to be reused. The development of the alternative fuels, such as ethanol instead of petroleum, allows us to substitute renewable for non-renewable resources. Fifty years ago, some conservationists were concerned about the exercise use of tin and copper. At the time, these were crucial commodities: Tin was used to make many countries, and copper was used to make telephone wire. Some people advocated mandatory recycling and rationing of tin and coppers so that supplies would be available for future generations. Today, however, plastics has replaced tin as a material for making food containers, and phone calls often travel over fiberoptic cables, which are made from sand. Technological progress has made once crucial natural resources less necessary. But are all these efforts enough to permit continued economic growth? One way to answer this question is look at the prices of natural resources. In a market economy, scarcity is reflected in market prices. If the world, were running out of natural resources, then the prices of those resources would be rising over time. But in fact, the opposite is more nearly true. The prices of most natural resources (adjusted for overall inflation) are stable or falling. Its appears but ability to conserve these resources is growing more rapidly than their supplies are dwindling. Market prices give no reason to believe that natural resources are a limit to economic growth. Sources: Adopted from Principles of economics, N. Gregory Mankiw QUESTION. 1.
