The main factors that affect distribution of population are natural resources, climatic conditions, soils, cultural factors, age of human settlement, industrial development and means of transport and communication. The factors affecting distribution of population are described below one by one in a nutshell manner.

Population growth refers to the growth of human population for a particular time and space. Population growth determines density, general distribution of population as well as population composition it shows that 1950 onwards population growth is more distinctive between developed and developing countries.

Environmental awareness needs to be created through formal and informal education to all sections of the society. Everyone needs to understand it because environment belongs to ‘all’ and ‘every individual matters’ when it comes to conservation and protection of environment.

A number of important environmental laws have been enacted in the form of Acts for safeguarding the environmental but still we are not able to achieve the target of bringing 33% of land cover under forests and we are losing our wildlife.

The Act came into force on Nov. 19, 1986, the birth anniversary of our Late Prime Minister Indira Gandhi, who was a pioneer of environmental protection issues in our country. The Act extends to whole of India. Some terms related to environment have been described as follows in the Act:

Salient features of the act are as follows:

Nuclear accidents can occur at any stage of the nuclear fuel cycle. The modern fusion bombs (nuclear bombs) are of explosive force of 500 kilotons and 10 megatons. Nuclear bombardment will cause combustion of wood, plastics, petroleum, forests etc.

1. The ozone layer serves as an umbrella or protective shield of the troposphere and saves the earth’s surface from most of the ultraviolet solar radiation by absorbing ultra-violet rays. As results of ozone depletion, the increased ultraviolet solar radiation in turn would raise the temperature of the earth and thus effect line forms as […]

Chlorofluorocarbons (CFCs), along with other chlorine, and bromine-containing compounds, have been implicated in the accelerated depletion of ozone in the Earth’s stratosphere. CFCs were developed in the early 1930s and are used in a variety of industrial, commercial, and household applications.

1. Improvement in technologies and switching to clean combustion technologies is highly essential. Coal with lower sulphur content is desirable to use in thermal plants.

Acid rain can affect drastically the ecosystem, aquatic and terrestrial biota. It can also affect the buildings and monuments. Finally, it affects the human beings.
