#LearnSustainability: Greenhouse gases

Nitrogen, oxygen and argon constitute the 99.93% of the natural gases present in the atmosphere. The remaining 0.07% is composed of water vapor, carbon dioxide, methane, nitrous oxide, ozone and artificial gases called chlorofluorocarbons, which are the ones that have a greater impact on the greenhouse effect.

These greenhouse gases that affect global warming are naturally present in the atmosphere, though their presence has hugely increased as a result of human action, mainly for three reasons: the burning of fossil fuels, forest deforestation and destruction of marine ecosystems and the increase of a population that increasingly consumes natural resources.
