What are the causes of pllution? how has pollonation affected europe?

Pollution is when contaminants are starting to evolve in the environment that can cause harm and discomfort to human beings or other living organisms. It can also damage the environment. The primary causes of pollution are industrialization and population growth. Industrialization is the process in which traditionally non- industrial sectors such as agriculture, education and health of an economy become increasingly similar to the manufacturing sector of the economy. It means individual labor is being replaced by mechanical equipments. Industrialization takes a big part of widespread usage of oil, gas or coal which is excessive use is the main source of pollution. Another cause is the population growth. If population number will continue to grow, the demand of foods and goods will increase as well as production. 
Air pollution is one of the types of pollution. Air pollution is one of the biggest problems Europe is facing. It affects mostly the healthcare and safety of the people around Europe especially for those who are living in the city and nearby plantation and manufacturing companies. Based on European Environment Agency, despite considerable improvements, air pollution is still responsible for more than 400, 000 deaths in each year.
