>Soil is an amazing thing and I think humans are only just getting a better idea of what's going on down there.

So true. A protein which makes up ~10% of soil by weight was only discovered in the 90s.

And only last year we discovered soil has a micro-biome too [1], and it has a profound impact on plant growth.

The most fascinating aspect of soil to me is that it's a natural carbon store, which for obvious reasons will become increasingly important in the coming years.
