More Underground Building
While we will see things like tunnels and whatnot built underground, you can also expect full buildings and ecosystems here. The world around us is going to be considering sustainability a lot more in the coming years. Rather than take up space above ground, it only makes sense to go below ground. While it could be that the underground territories will be for storage at first, this will change. Entire ecosystems might be found here, especially on the outskirts of some cities. This might be more common in places that have bad weather above-ground a lot. This does not mean we’ll see a lot of mole people here though. Rather, residential underground stuff might not be nearly as common as retail or eating locations.
