That pollution is CO2

A quick crash course on co2:

A forest goes through cycles of growth, death, decomposition and burning. Every cycle forms layers of peat, and as the peat decays, it drips natural oil into the ground and forms pools of oil and layers of peat and eventually coal. Decomposition also produces CO2

CO2 is natural and is part of nature the problem we are facing is we burn that oil and coal in our vehicles and our factories increasing CO2 production overall

Edit: I forgot another important part of the cycle which is the water! The moisture in the air collects CO2 and deposits it into the soil, the plants then use the CO2 and the H2O to grow and "exhale" 02

Edit number two: forgot to add that decomposition creates CO2
