Over thousands of years of human history, we’ve done an incredible amount. We’ve developed medicine, made incredible technological breakthroughs, and have colonized the entire world. Sadly, there has been an unbelievable amount of military force used in colonizing the world. Nation fighting against nation, just so we could plant our own flag where we darn well pleased. Millions of lives have been lost, just so we could say “this piece of dirt is our own”. It is believed, by and large, that this is the most effective way of going about making humanity the most dominant life-form on the planet. While we’ve been busy doing all this, there is another species that has quietly been colonizing the world, and it’s happening right under our feet.
