The interaction between primitive human society and strong forces of nature was termed as environmental determinism.

The relationship between the man and the environment has been established in the early periods itself. Human beings live in the kingdom of nature and interact with it constantly. The influence of nature in the form of the air he breathes, the water he drinks, the food he eats, and the flow of energy and information. Man is the species that most modifies environments and is responsible for the alteration and destruction of ecosystems. The destruction of habitats is the primary cause of the loss of environments and species extinction.

Sewage system - facility consisting of a system of sewers for carrying off liquid and solid sewage. sewage works, sewer system. facility, installation - a building or place that provides a particular service or is used for a particular industry; "the assembly plant is an enormous facility". In the ideal case, a sewer system is completely gravity-powered, like a septic system. Pipes from each house or building flow to a sewer main that runs, for example, down the middle of the street. ... The sewer mains flow into progressively larger pipes until they reach the wastewater treatment plant.

Knowledge of nature is important to develop technology which slowly loosens the shackles of environment on man. Human beings are better able to develop technology after they develop better understanding of natural laws. 2. When the level of technology is low the stage of human development is primitive. Nature is very importance of humans have needed to survive and thrive, was provided by the natural world around us : food, water, medicine, materials, for shelter, and even natural cycles such us climate and nutrients . Nature is our sole supplier. Some animals give us food.

The professional workers (White Collar) are the highly skilled workers, working in the areas like engineering or advanced scientific areas. They occupy a large share of workforce even more than the blue workers collar. They do mostly managerial work, engineering, finance, or research work.

The environment problems associated with urban settlements are as follows:
1. Pollution: The haphazard and uncontrolled growth of cities has led to environmental pollution including air noise and land pollutions.
2. Garbage problem: The higher quantity of garbage produced in the cities pollutes the land.
3. Environmental problems: As the urbanisation develops the problems for environment also develops. Different types of pollution such as land and water pollution develops.
4. Slums: The outskirt colonies of the city convert into slums.
5. Land pollution: As the cities grow in size they encroach upon the surrounding areas and expansion takes place. It creates land pollution. The garbage of the city accumulates on one place which pollutes the land.

Semple identifies four key ways that the physical environment:
1) direct physical effects (climate, altitude);
2) psychical effects (culture, art, religion);
3) economic and social development (resources and livelihoods);
4) movement of people (natural barriers and routes, such as mountains and rivers).

According to Fredrich Retzel, the German Geographer who is regarded as the Father of Modern Human Geography, human geography is a study of synthetical study of human societies and mutual relationship with surface of the earth.

Neo determinism refers human raceas a passive agent dictated by environmental, biosphere factors .

These factors determine their attitude, decision-making capability, and lifestyle.

The opposite criteria are determinism which refers to the point of view supporting environmental control on human action.

Neo determinism is the middle path of environmental determinism and possibilism.

In making the livelihood, the most land area clearly declares that this place is arid or semi-arid or desert.

Development is a mixed bag of opportunities as well as neglect and deprivations
for India:
(i)There are a few areas like the metropolitan centres and other developed enclaves that have all the modern facilities available to a small section of its population.
(ii)At the other extreme of it, there are large rural areas and the slums in the urban areas that do not have basic amenities like potable water, education and health infrastructure available to majority of this population.
(iii)The situation is more alarming if one looks at the distribution of the development opportunities among different sections of our society. It is a wellestablished fact that majority of the scheduled castes, scheduled tribes, landless agricultural labourers, poor farmers and slums dwellers, etc. are the most marginalised lot.
(iv)A large segment of female population is the worst sufferers among all. It is also equally true that the relative as well as absolute conditions of the majority of these marginalised sections have worsened with the development happening over the years.
(v)Consequently, vast majority of people are compelled to live under abject poverty and subhuman conditions.
