What if the Earth was flat?

I've been thinking about it lately, what if the earth was actually flat. Would we have all these problems with over-population, resources, pollution, climate change etc.<br><br>Because if the Earth was flat and you could walk off the edge, then we wouldn't have to worry about over-population, and all the resources that go with it.<br><br>The Earth is a sphere, but if it was a flat disc, then I think that we wouldn't have all these problems that are coming with over-population.<br><br>It would also probably be cooler to walk off the edge of the Earth.<br><br>Thanks for reading.
