So… Trees sucks in co2 and release o2 during day…. and doing the other way around at night… how would that help cleaning up air pollution then?

Call me stupid but I was told that while yes, Trees does absorb CO2 form the air and give Oxygen back during daytime. There’s also a reason to not have tree in your enclosed bedroom during night as it release all the CO2 absorbed.

So my question was that people are saying to plant tree to help purify the air in streets, city, or any dense population location. If the statement in first paragraph’s correct. wouldn’t that just result in that the trees would give the o2 and purify the air during day time and just flood the street with co2 during night? I’m confused…

Tress breathe in CO2 and breathe out O2

Humans breathe in O2 and breathe out CO2

It means that trees/humans have an internal process that concerts it from CO2 to O2 (or the other way)

So we both need each other. As far as day and night comment, it depends on the tree. It’s likely that certain trees need the sun to make the process; but it’s nominal.

Regarding your pollution. Too much CO2 in the world is bad, so thats why we need trees. Not only that, trees also provide shade which helps reduce the urban heat island.

There’s also the deforestation. The fact we cut down a lot of trees to make paper, cardboard, houses, lumber, etc. and we’re cutting faster than the trees are being planted and growing. So if we don’t encourage tree planting, there’s going to be a lot of CO2; which means there won’t be as much O2 then humans won’t be able to breathe.
