Pollution

Pollution is the introduction of pollutants which cause adverse changes in the natural environment. Pollution, such as noise, heat or light, may take the form of chemical substances or electricity. Pollutants, the emission elements, may either be foreign substances / energies, or pollutants that arise naturally. Contamination is also known as source point or nonpoint source emissions. Nine million people worldwide died of pollution in 2015. Pollution is the act of dirtying soil, water, air, or other parts of the world, which is not clean or suitable for use. This can be achieved by adding a contaminant into a natural ecosystem so it doesn't have to be visible. Things as basic as light, sound, and temperature may be considered contaminants when artificially introduced into an setting. According to Pure Earth, a charitable environmental group, industrial waste affects more than 200 million people worldwide. Babies are born with birth defects in some of the most contaminated areas in the world, children have lost 30 to 40 IQ points and life expectancy can be as low as 45 years due to cancers and other illnesses. Read on for more detail on different forms of emissions. More than 80% of people living in urban areas reporting air pollution are exposed to levels of air quality that surpass the WHO recommendations, with low- and middle-income countries facing the highest rates of exposure, both indoors and outdoors. From smog hanging over towns to smoking inside the house, air pollution poses a significant health and climate threat. The combined effects of ambient (outdoor) and household air pollution cause approximately seven million premature deaths each year, largely due to increased stroke mortality, heart disease , chronic obstructive pulmonary disease , lung cancer and acute respiratory infections.
