I'm generally against the idea of planting as many trees as possible.
Trees are not very good carbon sinks because they decompose and burn. Also, there are also some ecological communities where adding trees makes the land a worse carbon sink.
Avoiding cutting down forests to build suburbs is something I can certainly get behind though.
Electric cars are bad for the environment since they require mineral mining and polute the city with micoplastics from tire dust. They are almost as bad as ICE cars.
Ebikes are the way to go.
