Long Questions

“1. Translate the following paragraph into Urdu. OR Rewrite the paragraph in simple English:
More than 99 percent of the world’s food supply comes from the land, while less than 1 percent is from oceans and other aquatic habitats. The continued production of an adequate food supply is directly dependent on ample fertile land, fresh water and energy. As the human population grows, the requirements for these resources also grow. Even if these resources are never depleted, on a per capita basis they will decline significantly because they must be divided among more people. At present, fertile agricultural land is being lost at an alarming rate. The shortage of productive fertile land combined with decreasing land productivity is the major cause of current food shortages.”
“2. Translate the following paragraph into Urdu. OR Rewrite the paragraph in simple English:
Water is another critical item for all crops. Massive amount of water is required during the growing season for cultivation. In fact, agricultural production consumes more fresh water than any other human activity. In many countries, people are facing shortage of fresh water. Competition for water resources among individuals, regions, and countries and associated human activities is already occurring with the current world population. Water resources, critical for irrigation, are under great stress as populous cities, states, and countries require and withdraw more water from rivers, lakes, and aquifers every year. A major threat to maintaining future water supplies is the continuing over-use of surface and ground water resources.”
“3. Translate the following paragraph into Urdu. OR Rewrite the paragraph in simple English:
Fossil energy is another prime resource used for food production. Nearly 80 per cent of the world’s fossil energy is being used by the developed countries. The intensive farming technologies of the developed countries use massive amounts of fossil energy for fertilizers, pesticides, irrigation, and for machines as a substitute for human labour. In developing countries, fossil energy has been used primarily for fertilizers and irrigation to help maintain yields rather than to reduce human labour inputs. Because fossils energy is a finite resource its depletion accelerates as population needs for food and services escalate. Thus, cost of fuel increases everywhere. “
“4. Translate the following paragraph into Urdu. OR Rewrite the paragraph in simple English:
Certainly improved technology will assist in more effective management and use of resources, but it cannot produce an unlimited flow of those vital natural resources that are the raw materials for sustained agricultural production. For instance, fertilizers enhance the fertility of eroded soils, but humans cannot make topsoil. Indeed, fertilizers made from finite fossil fuels are presently being used to compensate for eroded topsoil. A productive and sustainable agricultural system depends on maintaining the integrity of biodiversity. “
“5. Translate the following paragraph into Urdu. OR Rewrite the paragraph in simple English:
The alarming and incessant growth of population is causing serious economic problems in almost all continents. Great pressure is being placed on arable land, water, energy, and biological resources. As the world population grows, the food problem will become increasingly severe. The most vulnerable will be population in developing countries. The per capita availability of food grains has been declining for the past 25 years. Certainly, with a quarter million people being added to the world population each day, the need for grains and all other food will reach unprecedented levels. “
