Food Resources: Fertilizers -Pesticide problems Solution; Organic farming

<p>Food refers to any substance that is ingested and is utilized by the body for growth and<br>sustenance of life. In other words, natural or artificially produced materials that are used as<br>food to derive metabolic energy are called food resources. Food is the ultimate source of<br>metabolic energy required for growth, body repair, body heat balance, and daily activities.<br>There is a wide gap between developed and developing countries about the production of<br>food. In spite of several efforts, many countries of the world are still facing acute problems of<br>food shortage and starvation. One of the factors that have been contributing to food problems<br>these days, especially in developing countries, is the production of biofuels. It is been<br>reported that the use 0of food crops, such as corn, to produce ethanol is driving up the prices<br>of the corn, and the increased production of palm oil and soybean is leading to the<br>destruction of large areas of rainforests. Global experts predict that to feed the world's<br>growing population, some 500 million new acres of cropland will be needed by 2030, a 20%<br>increase. Accumulation of water on the land for a long period is known as water logging.<br>Rain, over-irrigation, and inadequate drainage cause excess water to accumulate in lowlands.<br>Due to all these factors, moisture percolates down and dissolves the underground salts in it<br>which come to the surface after the water evaporates.</p>
