Human beings were able to develop proper technology using his knowledge and intelligence. It has taken man a long time to reach at the present level of technology. In primitive age when the level of technology was very low man was bound to follow the dictates of nature. In those times man was a slave of nature, scared of its powerful force and used to worship nature to make it happy. In these conditions the state of cultural development was also primitive. However, the process was gradual but man developed technology and it is also to be noted that man has been able to utilise this technology only after understanding the various laws of nature. For example; understanding of laws of friction gave birth to many inventions. Similarly after understanding secrets of DNA and laws of genetics, man has overcome many diseases and aeroplanes could be invented only after understanding the laws of aerodynamics.Today the level of technology is touching the heights of sky through which man seems to get free from the natural forces. Earthquake, cyclones, landslides, volcanoes and other natural disasters keep reminding man that he is still a slave to nature.. Technology helped in reducing the harshness of labour, increased labour efficiency and provided leisure to human beings to attend to the higher needs of life. It also increased the scale of production and the mobility of labour.

Human geography or anthropogeography is the branch of geography that deals with the study of people and their communities, cultures, economies, and interactions with the environment by studying their relations with and across space and place. Some examples of human geography include urban geography, economic geography, cultural geography, political geography, social geography, and population geography. Human geographers who study geographic patterns and processes in past times are part of the subdiscipline of historical geography. Human geography is a wide-ranging discipline that draws together many of the strands important for understanding the world today. It examines human societies and how they develop, their culture, economy and politics, all within the context of their environment.

Chandigarh is India's first planned city and is known for its layout, which was 'designed for the people'. It has a great history! At the time of partition in 1947, when Pakistan was carved out of western Punjab, the then capital, Lahore, went over to the other side. Also known as Banaras and Kashi situated on the bank of the holiest river of India“Ganges”. Varanasi “The city of temples” is one of the oldest city in the world. Varanasi is also known as the “Religious capital of India”. The city has been a culture and religious center in India for several years.

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. When the level of technology is low the stage of human development is primitive. Man adapts to the dictates of nature (Environmental Determinism).

With social and cultural development, human beings begin to understand nature, develop more efficient technology and move from a state of necessity to a state of freedom.

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).
