Air pollution is the contamination of air by smoke particles and harmful gases. When the atmosphere is filled with toxic gases released as result of industrial or other economic activities, it results in polluting the atmosphere and the air in the environment. They are mainly oxides of carbon, nitrogen and sulfur. Some of the main causes of air pollution include: the burning of fossil fuels like oil, gas or coal; forest fires, the exhaust fumes from your vehicles, the mismanagement of landfill waste caused by garbage pollution and nuclear accidents or radiation spills.
Air pollution can be harmful even when it is not visible. Newer scientific studies have shown that some pollutants can harm public health and welfare even at very low levels.
Air pollution causes around seven million deaths a year worldwide. Growth and concentration of the population in cities, as well as the way in which we consume energy in urban areas through transport or heating and air conditioning systems, among others, result in the emission of huge quantities of gases that are harmful to our health.
The World Health Organization (WHO) and the Climate and Clean Air Coalition (CCAC) – made up of the United Nations Environment Programme (UNEP) and 54 nations, among other agencies – launched the BreatheLifeinitiative.
This is a program that aims to “aims to mobilize cities and individuals to protect our health and our planet from the effects of air pollution” and which has fixed the objective of cutting by half the number of deaths linked to air pollution before 2030.
Actions will be local and focused on improving transport, waste management, indoor air quality, energy supply, industry, food and agriculture.
