Pollution definition

Pollution is anything that affects our environment or our health, usually in the form of substances, but also in the form of waves. Pollution attacks the air, water, soil, our ears, our eyes …

pollution meaning

Let’s get some fresh air. At the moment, there is a lot of talk about greenhouse gas pollution. These gases are released by cars, trucks and some factories. Carbon dioxide, or CO2, is one of them. However, CO2 has always existed naturally in nature. Animals release it every day when they breathe. If carbon dioxide is considered a pollutant today, it is because it has accumulated unnaturally in the air over the past hundred years.

Most of the time, pollution of soils and rivers is chemical or biological in origin. It comes from factories, agricultural fertilizers, the discharge of wastewater by human beings … The cooling circuits of factories discharge hot water into rivers. Some algae start to proliferate and fish die. This is called thermal pollution.

Astrophysicists love to look at the starry sky on a dark night. From their perspective, city lights are light pollution. And each of us is regularly annoyed by the noise of cars or motorcycles in the street or by the noise of neighbors behind a party wall … this is called noise pollution.

The whole world is suffering from pollution which is becoming a very dangerous problem. There are three kinds of pollution: Air pollution caused by smoke from factories and transportation. Water pollution from waste dumped in the sea and rivers, and soil pollution from chemicals and human activities.

Pollution by country

The three most carbon dioxide (CO2) polluting countries are, unsurprisingly, the three most industrialized countries in the world: China, the United States and India. However, their carbon footprint compared to the number of inhabitants gives a very different result.

In 2019, global CO2 emissions reached 34.1 million tonnes of CO2 in the atmosphere, a record that is likely to be quickly exceeded since the forecast trajectories do not foresee any decline.

It is thus the most populated and industrialized countries which appear at the top of the ranking of the most polluting countries in the world. The three countries with the largest CO2 emitters are therefore :

  • China with 9.8 million tonnes of CO2 emitted largely due to the export of consumer goods and its heavy dependence on coal;
  • The United States with 4.9 million tonnes of CO2 emitted;
  • India with 2.4 million tonnes of CO2 emitted.

Germany is by far the most CO2 emitting country in Europe due to its heavy dependence on coal. Thus, ¼ of the European Union’s CO2 emissions come from Germany. France escapes the classification thanks to nuclear power, the majority energy in the country.

The consequences of pollution

Pollution has serious consequences on public health and on animal and plant species, it causes respiratory diseases, Global warming, The disappearance of flora and fauna. To solve this problem, we must be aware of this threat and adopt an attitude aimed at putting an end to this degradation of our environment.

Some tips to avoid pollution

It is very difficult to have a city with clean air without pollution, but we can do some efforts to reduce this pollution. Here are some tips :

  • Establishment of laws to be respected especially by polluting industries;
  • Do not throw waste into the river water;
  • Do not light fires in forests;
  • Sensitize people to participate in the protection of the environment;
  • Use public transportation;
  • Grow more plants and trees;
  • Do not use the car one day a week;
  • Do not burn waste;
  • Do not use chemicals;
  • Devote more space to pedestrians;
  • Limit the cutting of trees and sensitize people to the problems of deforestation.

A day without a car

The use of the car in the city causes many problems such as air pollution, noise, and climate change. If we leave our car in the garage for a day what are the advantages ?

  • A day without a car reduces atmospheric pollution;
  • With fewer cars, more noise pollution is avoided;
  • The surrounding temperature will decrease by a few degrees, and this will correct the causes of global warming;
  • The air quality improves and as a result we breathe clean air;
  • The entirely pedestrianized districts multiply.

We all participate in pollution and each of us will have to make an effort to protect our environment, our health and our future.
