Our Walls

We, humans, have essentially removed ourselves from the competition of nature. As such, I am not certain that we are continuing to evolve naturally. That's not to say that I think it is a bad thing, we are in control of technology which I think is better for evolution; nature can only give us so much non-immortal, largely inadequate things. So, it seems like it is best that we remove ourselves from nature; we no longer have to struggle in the same way that animals living day-to-day do.We have built our walls that protect us from nature, though we hardly have any natural predators anyway. These walls keep us safe and allow us to focus on other things. We get our food inside these walls, and we can focus on improving ourselves through technology. We are learning how to sustain ourselves while creating protection from threats, at least the threats that we don't make for ourselves.
