Emissions

Emissions

In an environmental context, emissions are toxins or chemicals released into the atmosphere which cause air pollution and consequently affect the health of humans, animals, plants and ecosystems negatively. The major pollutants caused by human activity are sulphur oxides, nitrogen oxides, carbon monoxide and ammonia, among others. Emissions may also refer to the emission of greenhouse gases, which are gases that absorb radiation and emit it in different directions. Although the Earthhas natural greenhouse gases that allow human life as we know it, human activity has led to a massive increase in the production of greenhouse gases and contributes substantially to global warming.
