Will we be able to see permanent or lasting effects of weather in the environment, like lightning, damaged trees, et cetera?

We have this plan that the terrain changes if you have big explosions, grenades and stuff like this go off. You can have a hole there, which is not going to be permanent, because there's thousands of people coming there and throwing their grenades. So it's going to go away after a while, it's not going to be permanent. But we were also thinking about, if you want to harvest resources, like hacking down trees and stuff like that, that the resources kind of shift after, say, a couple of months of people chopping down all this wood. And so the density of the forest goes down after some time. So you can notice it, like, oh, shit. And then the landscape does change and you can see it visually.
