How do we stop wars and bombing because the bombs and vehicles make a lot of pollution?

This is a really good question! Unfortunately, I do not have the solution to stop wars and bombing... However, it is true that wars produce a lot of pollution, and there are a couple of rules that countries must respect to protect the environment during war time.

One rule prohibits countries at war to damage the natural environment, especially if the damage is expected to be serious. This is because people rely on the environment to survive and be healthy (for food, water, and shelter for instance). Another rule prohibits countries at war from setting forests and other vegetation on fire, to protect plants, animals, and their habitats (where animals live).

Another important rule prohibits countries to use environmental modification for military purposes. This means that countries cannot modify the environment to cause damage to their enemy (by provoking floods, for instance).

All these rules are quite old, and they were agreed on when the protection of the environment was not such an important issue. Now that we know that wars produce a lot of pollution, it may be time for countries to think about updating these rules.
