The number of people on Earth, where they live, and how they live all affect the condition of the environment. People can alter the environment through their use of natural resources and the production of wastes. Changes in the environmental conditions, in turn, can affect human health and well-being.

Many people worry that population growth will eventually cause an environmental catastrophe. However, the problem is bigger and more complex than just counting bodies. We humans are remarkable creatures. From our humble beginnings in small pockets of Africa, we have evolved over millennia to colonise almost every corner of our planet.

This paper summarizes research on the effect of population growth on environmental quality. Land transformations induced by the spatial expansion of agriculture are probably the major route by which population growth has affected features of the natural environment. These transformations are not automatic and their extent is influenced by social institutions. Intensification of agricultural land use is an alternative response with its own set of environmental implications. These are especially salient in the case of expanded irrigation. Nevertheless, population policy may play a useful role in strategies to reduce industrial pollution.

Population and the natural environment

Biodiversity is the range of different species present in the community of an ecosystem. The biodiversity of ecosystems can be affected by population growth, human activities and natural hazards. Like all living organisms, humans exploit their surroundings for resources. Before the beginning of agriculture about 10, years ago, small groups of humans wandered across large areas, hunting and gathering just enough food to stay alive. Population numbers were kept low because of the difficulty of finding food. The development of agriculture led to a population explosion that has accelerated enormously during the past years.

The value placed upon large families especially among under-privileged rural populations in less developed countries who benefit least from the process of development , the assurance of security for the elderly, the ability of women to control reproduction, and the status and rights of women within families and within societies are significant cultural factors affecting family size and the demand for family planning services. Even with a demand for family planning services, the adequate availability of and access to family planning and other reproductive health services are essential in facilitating slowing of the population growth rate. Also, access to education and the ability of women to determine their own economic security influence their reproductive decisions. The magnitude of the threat to the ecosystem is linked to human population size and resource use per person. Resource use, waste production and environmental degradation are accelerated by population growth.

John P. Holdren , Paul R. It is more important now than ever to talk about population. What will we do if we continue to grow at exponential rates? What are ethical, viable strategies to decrease population?

Population growth would not be sustainable if it has important negative impacts that will jeop- ardize the ability of future generations to meet their needs. First, let's.

Effects of Population Growth on our Environment

A United Nations report released in puts the current world population at 7. By this number is expected to increase to 8. With a handful of countries being primarily responsible for this growth, about 83 million people are being added to the population each year even though it is expected that fertility levels will continue to decline.

While the causes are complex, one significant contributor to the problem is population growth. Understanding the relationship between population growth and environmental issues may be the first step toward identifying real solutions. Population growth is the increase in the number of people living in a particular area. Since populations can grow exponentially, resource depletion can occur rapidly, leading to specific environmental concerns such as global warming, deforestation and decreasing biodiversity. Populations in developed countries trend toward using substantially more resources, while populations in developing countries feel the impacts of environmental problems more quickly.

One of the factors responsible for environment degradation is population growth or population density. In particular, population density plays the most important role in shaping the socio-economic environment. Its effects are felt on the natural environment also. Due to his destructive activities, man has dumped more and more waste in environment.
