Introduction

Air pollution refers to the contamination of the atmosphere by harmful substances that alter its natural properties and cause harmful effects for living beings and the environment. This crucial component for life is facing the challenge of pollution, which is one of the most alarming environmental problems of this century. In the development of this article, we will talk about the constituents of air, the causes of pollution, the consequences and the prevention against air pollution.    

The constituents of air and the causes of air pollution

The atmosphere is made up of nitrogen, which all living things need. Nitrogen is an essential component of chlorophyll, the main pigment crucial to photosynthesis, and is essential for all DNA and RNA in the cells of living beings.   Oxygen enables the body to function properly, while carbon dioxide plays an essential role in the vital processes of living beings and plants. There are also rare gases such as helium and neon. The atmosphere also contains water and a large amount of dust. The factors that cause air pollution are numerous, but the main cause of air pollution is human activity. Among these activities is the combustion of fossil fuels, a process by which these fuels, such as coal, oil and natural gas, are burnt to produce energy. This energy, in the form of heat, can be used to generate electricity, power vehicles, etc. Burning fossil fuels emits greenhouse gases and atmospheric pollutants. Industry also plays a role in this scourge, with the production of materials and chemical products, waste processing and the transport of goods. Intensive farming can contribute to air pollution in a number of ways, with the intensive use of chemical fertilisers and pesticides, and intensive ploughing of soils can release organic carbon into the atmosphere, contributing to climate change.

 Consequences and prevention of air pollution

  Air pollution can have a number of consequences for biodiversity, including a deterioration in the quality of the habitat of animal and plant species, which can lead to a reduction in the diversity of species present in an ecosystem. It can also lead to health problems in animal and plant species, which can reduce their ability to reproduce, feed or protect themselves. This pollution can disrupt the natural cycles of species, such as reproduction, which contributes to imbalances in the ecosystem. It can also lead to the disappearance of certain animal and plant species that cannot survive in a polluted environment. The world’s population is exposed daily to air containing high levels of pollutants. Many regions are affected by worrying levels of pollution. Major metropolises are confronted with veritable scourges of air contamination, causing thousands of premature deaths every year and environmental problems. To combat this phenomenon, it is crucial to reduce dependence on fossil fuels, improve transport infrastructures and raise public awareness of the eco-responsible gestures to adopt. 

Conclusion

Air pollution is a problem that requires urgent action on the part of governments, businesses and citizens. It is imperative that we take concrete steps to reduce pollutant emissions and protect our environment. By adopting more planet-friendly behaviour and actively campaigning for stricter environmental policies. Preserving air quality guarantees a healthy future for generations to come.
