The more greener it is with the trees the more Oxygen they create.And the more protesters who have no idea what they are protesting about.Must be something in the air or the amount of Happy Baccy going around.Would love to be alive when they are in between 60-70 and all got C O P D .
That's a strange simplistic argument there.
Having studied climate as part of my degree I can assure you it's not as simple as yet. Yes, plants take in CO2 and 'breathe' out Oxygen, but that doesn't make the air cleaner, or cool it down significantly. Plants utilise CO2 as part of their structure (like we use calcium in our bones) but once that plant has died that CO2 gets released back in to the environment. In the case of trees that can be hundreds of years, but annual plants or perennials will release their CO2 as soon as they die back each winter. One large forest fire will undo many decades of CO2 storage in trees.
Plants also emit CO2. Whilst they are growing they do take in more CO2 than they give out, but when a plant, or tree, is established and not going through a growth spurt they give out as much CO2 as they take in & so have no effect on the CO2 in the atmosphere.
Also, CO2 is also not the only pollutant that comes from car fumes - there's Nitrogen Dioxide for example.
