How does water re-stabilize the planet ?

every living organism needs water to survive, I think, trees, which give off oxygen while taking in carbon and gives off oxygen and trees and plants need water so technically with no plants/trees no one would be here

acid rain does not usually kill trees directly. instead, it is more likely to weaken the trees by damaging their leaves, limiting the nutrients available to them, or poisoning them with toxic substances slowly released from the soil. the main atmospheric pollutants that affect trees are nitrates and sulphates.
