Answers
Answer:
1. Urban people change their environment through their consumption of food, energy, water, and land. And in turn, the polluted urban environment affects the health and quality of life of the urban population. ... For example, urban populations consume much more food, energy, and durable goods than rural populations
2. Chlorofluorocarbons bind to ozone, and the chemical reaction releases a chlorine free-radical capable of destroying thousands of molecules of ozone.
3.
Domestic and Municipal Wastes: One of the main causes of land and soil pollution is the growing quantity of domestic and municipal wastes. ...
Industrial and Mining Wastes: ...
Agricultural Wastes: ...
Radioactive Materials: ...
Biological Agents:
4. The most obvious and immediate reason for reducing energy consumption is probably the reduced costs that result from doing so. Burn less fuel and you will buy less fuel

Reasons to Save Energy
Updated April 25, 2017
By Judith Willson
You are probably aware that cutting your energy consumption with small or large lifestyle changes helps the environment, and you have almost certainly noticed that it usually cuts some bills, especially for fuel and power. The reasons to save energy, however, extend beyond the obvious.
Money
The most obvious and immediate reason for reducing energy consumption is probably the reduced costs that result from doing so. Burn less fuel and you will buy less fuel. When you use less electricity and gas in the home, your utility bills become a bit smaller. The more indirect ways of saving energy -- for example, buying goods that are second hand rather than new -- may also save money. While saving the planet may appeal to the socially aware, perceptible monetary benefits may encourage more people to save energy.
Air Pollution
Air pollution kills hundreds of thousands of people a year prematurely, according to the World Health Organization. It also exacerbates lung and heart problems and causes acid rain. Air pollution makes a walk in a highly polluted city a thoroughly unpleasant experience. Because air pollution mainly comes from the burning of fossil fuels, and much of the world’s energy is still produced this way, reducing energy consumption helps to reduce associated environmental problems and their negative impacts on everyday living and personal well-being.
Reducing energy consumption can help reduce the greenhouse gases that contribute to global warming. When it comes to such large-scale global problems, people can feel utterly helpless in the face of a seemingly overwhelming situation.
