Pollution -  A major issue of Urbanization

Pollution, also called environmental pollution, the addition of any substance (solid, liquid, or gas) or any form of energy (such as heat, sound, or radioactivity) to the environment at a rate faster than it can be dispersed, diluted, decomposed, recycled, or stored in some harmless form. The major kinds of pollution, usually classified by environment, are air pollution, water pollution, and land pollution. Modern society is also concerned about specific types of pollutants, such as noise , light pollution, and plastic pollution. Pollution of all kinds can have negative effects on the environment and wildlife and often impacts human health and well-being. 

Due to the increasing amount of population, the amount of pollution is also increasing in urban areas . Hence it is a major issue of urbanization 

Types of pollution -

• Air pollution is a mixture of solid particles and gases in the air. Car emissions, chemicals from factories, dust, pollen and mold spores may be suspended as particles. Ozone, a gas, is a major part of air pollution in cities. When ozone forms air pollution, it's also called smog. 
  
• Water pollution is the contamination of water bodies, usually as a result of human activities. Water bodies include for example lakes, rivers, oceans, aquifers and groundwater .
  
• Land pollution is the deterioration (destruction) of the earth's land surfaces, often directly or indirectly as a result of man's activities and their misuse of land resources.

HOW CAN WE AS INDIVIDUALS REDUCE POLLUTION?

Here are some simple steps which we can take as individuals to reduce pollution :-

• Commute smart by walking or riding to work or the shops instead of driving. Motor vehicle emissions remain the most significant source of most common air pollutants
• Save energy, by turning off the television and make sure you flick the light switch when you leave the room. Not only will you save money on your electricity bill, you will be reducing emissions from coal-fired electricity plants.
• Use environmentally friendly cleaning products. Phosporus in detergents increases nutrient loads in rivers and can cause excessive algal growth. Never pour chemicals or fertilisers down the drain as they get washed into stormwater drains and into rivers or the ocean
• Limit driving by carpooling, using public transportation, biking and walking.
• Keep out oils, fat, or grease from the sink.
