What would the world look like in the absence of modern civilization? By the time anyone figures out the answer to that, we, the people in this time, will be long gone.

Somewhere down the line, we've often wrestled with the idea that maybe, just maybe , we weren't supposed to build all that we've built. And time after time, nature also does her best to remind us of that. No wonder she keeps creeping into what we've created.

Here are some photos that show how nature decided that it's time to take the world back from us.
