This is a very nice overview of humans. We have the intelligence, yet countries are at war with each other. Our intelligence doesn't help us realize that we need to do what's right for everyone and everything. We could have learned from the different animals; like how ants work together, or how bees have a mutually beneficial setup with their food.

I do think that once we've perfected lab grown meat, it will only be a matter of time before people switch to it.
