I hate when writers describe plants as an ongoing carbon sink. They are a one-time carbon sink. So using "cars" as a comparison to carbon volumes is confusing, because cars will keep emitting after a plant is full grown and starts shedding leaves and wood that turn back into methane or carbon dioxide.

The key benefit of the plants is cooling the city without electricity, which is an ongoing effect.

Similarly, we can't plant enough trees to offset our total carbon emission because we've released SOOO much carbon that was previously just buried underground as oil. We would need to plant more trees than we have ever seen.

More trees than have ever existed, given we burn both coal (trees) and oil (algae)... and a loooot more oil.

Depends how you manage them, and their detritus

If you burn it, you are correct

There are other approaches that sink the carbon and improve soils.
