The Effects of Overpopulation on the Environment Essay

On 12 October 1999 the world 's population reached 6 billion people. It will reach 3 billion by 2050. Most countries already feel the impact of continuing population growth. Overpopulation is the fundamental cause of most environmental problems. The need for population growth has increased the demand for natural resources, clean air and water, and the entrance to the wilderness. This means an increase in demand for living space. The quality of life for future generations will depend on stabilizing the domestic and world population

5) Only Western style contraceptive techniques and educational programs can lower the birthrate. Providing basic education is difficult in all developing countries.

Population growth is not the only pressure on the environment. To raise the living standard of developed countries, more environment is necessary

More people means less land for plants and animals. Human beings can reduce the amount of land for other animals and plants in the main way.

More people mean more environmental damage. Human activities can contaminate all three parts of the environment.

1) Water containing sewage, fertilizer and toxic chemicals. The use of fertilizer leads to eutrophication

Overpopulation is becoming a big environmental problem, and resources are consumed faster than they are produced. Mr. Hoevel explained that "population density will exceed population density if it exceeds environmental capacity to meet individual health needs" (Hoevel 1). This means that if the group uses the resources of a particular area too much, the environment will not support them and there will be population problems. Wenner explained as "sustainability"

Overpopulation can have some impact on the environment and other species in the ecosystem. In fact, overpopulation has led to technological progress that improves human life and fertility, and puts pressure on global resources. Due to this influence, the earth entered a new geological era called humanity era. Generally, due to exhaustion of resources, overpopulation can cause damage to ecosystems. Such damage could result in a decline in other population competing for the same resource. In many cases, this effect results in a cycle between population growth and population decline until a steady state is reached at a particular niche. Some examples of naturally regulated population growth are rodents, rabbits, and various insect populations (eg military insects and ticks).
