| Research Abstract |
The human population at the global level has been growing exponentially over time. The absolute number of humans has continued to increase to more than 6 billion at the end of the twenty century, and the distribution of the each country's population has changed, due to differing birth and death rates in a country even if in a developing country like China or India. Developing countries' population also continues to increase much faster than developed countries ; however the increasing rate of population has been decreasing in decades. The three factors which have the great impact on the population of any nation are total fertility rate (TFR), international migration and mortality rate (death rate). The total fertility rate is the average number of children a woman gives birth to in her lifetime. A population with a large percentage of people in the economic active years (15-64) will continue to increase production and technological invention even if parents do not produce enough childr

Many environmental problems can be attributed to poor management techniques or policy failure for the protection. Such factors are largely independent of population, but the sheer number of people can also contribute to the problems. Consider, for example, the issue of consumption of material resources. As monetary wealth has increased, so has consumption. As a nation we now own more goods, use more energy, eat more processed food and need larger amount of resources for their higher standard of living than ever before. All this consumption can create environmental problems. Factors such as population growth, population de-aging combine with high-consumption patterns at the international level to put stresses on the environment. There is a limit to the environment in terms of supply of natural resources including forest, water and soil, and the ability to absorb emissions of greenhouses gas and waste products. Examples include the rate of tree growth for timber harvesting, the available fresh water for irrigation and human consumption, and the time required for the recycling of organic waste. Land degradation, loss of forest cover, pollution of water and air, soil erosion and loss of biodiversity are all occurring at a fast pace, and are evidence of the impact of an increasing population on the environment.
