THE CONSEQUENCES OF AIR POLLUTION
Environment
Air pollution is caused by the presence in the atmosphere of toxic substances, mainly produced by human activity in recent years. These gases and chemicals generate a number of phenomena and consequences for the ecosystems and living things that populate our planet.

air-pollution effects

Air pollution affects everyone and all sectors: animals, crops, cities, forests, aquatic ecosystems ... In recent years, however, we have been interested in two areas in particular, which are subject to numerous adverse consequences of air pollution: the environment and human health.

The consequences of air pollution on the environment

Polluted air, floating on the surface of the earth, is washed away by wind and rain. Clouds and high temperatures also help disperse pollution to reach very long distances from its point of origin.

Air pollution has a major impact on the process of plant evolution by preventing photosynthesis in many cases, with serious consequences for the purification of the air we breathe.

The accumulation of gases in the atmosphere also generates environmental problems with sadly known consequences: acid rain, depletion of the ozone layer, global warming, greenhouse effect ... The concentration of these gases in the atmosphere, mainly the dioxide of carbon, increases on average by 1% per year. This phenomenon is due to the properties of certain gases (carbon dioxide, methane, nitrous oxide, ozone and chlorofluorocarbons) to trap the heat of the sun in the atmosphere, preventing it from returning to space after having been reflected by Earth.

Air pollution contributes to the formation of acid rain, atmospheric precipitation in the form of rain, frost, snow or fog, which is released during the combustion of fossil fuels and transformed by contact with steam. water in the atmosphere. Acid rain changes the amount of chemicals in soils and fresh water, affecting food chains.

The consequences of air pollution on human health

Our continued exposure to these air pollutants is responsible for the deterioration of human health.

Air pollution can cause cardiovascular problems, allergies, asthma attacks, conjunctivitis, bronchial diseases, lung or skin cancer, vision problems, blood problems in the child's mental development, among others. The most vulnerable people are children, the elderly, pregnant women and the sick.

Thus some scientists have been able to establish a direct relationship between the increase of polluting particles in cities and the thickening of the internal lining of the arteries or atherosclerosis. Many studies have also found that groups of people living near busy urban areas have more respiratory problems than average and are more likely to develop disease. There are many more cases of children with bronchitis and slow lung development in large cities.
