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…

The net difference between the intake and output of CO2 is equal to the mass of the tree.
Observation: to use trees to permanently remove CO2 from the atmosphere, you have to grow the tree then sequester the wood. For example, use the wood to build a house. If you burn it then the CO2 will be replaced. Likewise, if you leave it alone then organisms will eat the wood and fart out a tree worth of CO2.
