Agriculture and Population Growth Essay -- Agricultural Economy Scienc

Agriculture and Population GrowthThe earth is change magnitude its people by 90 million people per year, and yet we unagitated have 5.9 billion people left to feed and to give furnish (Mitchell, 1998). Along with the gain in the population, there are also much people on Earth who are living longer lives. The cosmos-wide population boom has coincided with the improvement of health, and of productivity, around the world. On average, the human population today lives longer, eats better, produces more, and consumes more than at any other cadence period in the past (Eberstadt, 1995). Agriculture feeds people, but will it be able to feed the expanding global population, especially with its exponential increase? i way for the population of today and tomorrow to live in musical harmony in regards to nourishment provided by the environment is to be able to rise agricultural yields. With a projected population of 10 billion people, an increase of global average atom yields from 2 t o 5 tons of grain per hectare would ensure a per capita diet of 6,000 calories and would save a land sports stadium twice the size of Alaska (Waggoner, 1994). Most of the worlds increased product is no longer a result of expansion of area employ in culture, but resulting from the intensification of production on existing agricultural areas. In the last 50 years, agriculture has intensified and yields per hectare have been rising. Intensification has allowed for a heterotaxy of destruction of land. More land has been spared due to increased intensities. In India, 42 million hectares of land have been spared, approximately the size of California and globally, the world has saved an area the size of the Amazon (Ausubel, 1996). Of all human activities, agriculture transforms the... ... and supported in a sustainable manner, agricultural intensification might sightly be able to keep up with the demand. In the up-coming decades, we will short find out. BibliographyAusubel, Jesse H. 1996. Can Technology Spare the Earth? Scientific American 84 Pages 166-178. Brown, Lester R. 1997.
