Why are green house gases considered pollution?

Answer 1

Greenhouse gases are not necessarily pollution. In fact, the main greenhouse gases, water vapour and carbon dioxide are certainly not pollutants. On the other hand, ozone is a greenhouse gas and a pollutant, because it can be injurious to human health.

Although not a pollutant in the normal sense, increased atmospheric levels of carbon dioxide do lead to global warming, which does have a harmful impact on our environment.

Answer 2

Greenhouse gases are considered pollution because when they accumulate in the atmosphere, they trap heat and contribute to global warming and climate change. This can lead to various negative impacts on the environment, such as rising temperatures, sea levels, and more frequent extreme weather events.
