article on "Impact of overpopulation " in about 120 words
Answers
Answer:
At the time of the agricultural revolution, nearly ten thousand years ago, the population of the globe was no more than ten million. Today the world population is estimated at over six billion. In the last hundred years the population has more than tripled. With the population rising at an enormous rate of 1.7 million a week, the world as a whole is being drained of its resources. (Southwick, 1996) Different theories have prevailed on what will occur as the population continues to explode ranging from the Malthusian apocalypse to absolutely no effects at all. Over the last two centuries as agricultural and technological advancements came about, the planet's overall carrying capacity increased dramatically. It is estimated that the world could support over twenty times its current population living at 120 per square meter in 2000-story buildings. (Dolan, 1974) Overpopulation not only adversely affects the "environment," or nature, but also has a large impact on human societies today.
Environmental degradation and population growth go hand in hand. As more people enter the world, there is a greater need for space, furthering damage to our surroundings. As populations grew in response to the agricultural revolution of ancient times more land was required for cultivation to feed the rising populations. Forests were cleared, waterways were diverted, and the soil exhausted, all a result of the expanding populace. Even today in parts of the world, especially third world countries, land is being cleared by slash and burn methods for grazing land and urban development. Whole species of organisms in areas like the Amazon rainforest have most likely been lost due to this method of deforestation. As areas are cleared in the way for future generations, land is becoming extremely scarce. It has been estimated that between 1 and 2 billion people could be supported on this planet in relative prosperity. The estimate comes from the availability of energy resources, agricultural land coupled with increased pollution control, recycling, and sustainability. (Southwick, 1996) The world today faces tremendous problems with poverty, disease, and famine as a result of the booming populations.
Overpopulation has greatly affected today's societies throughout the world. Certain countries, especially in the developing nations.

Answer:
Overpopulation is the condition where the number of existing living creatures and human population exceeds the limited habitats and resources to sustain them. Overpopulation of human is caused by higher rate of birth and lesser rate of death. Longevity of life and less mortality results from better medical care, awareness of hygienic living conditions, proper physical health awareness, balanced diet and better mother and child care before and after birth.
Various problems are associated with population explosion. The increased population puts pressure on our resources such as land, water and food as the demand increased. Overpopulation results in food scarcity, starvation and malnutrition. Overpopulation results in depletion of natural resources like fossil fuels and destruction of forests for housing and timber industries.
Human overpopulation causes greater pollution of air, land and water. This decreases the quality of life and results in various diseases and health problems. While man power is necessary for agricultural and industrial production, overpopulation leads to unemployment. The economy of a nation is affected adversely. Law and order situations also deteriorate. The number of homeless people, refugees and slums increase at an alarming rate. People must be educated and awareness on the hazards of overpopulation for mankind needs to be taken up urgently. The best means to control overpopulation is by practicing family planning.
