Ok, imagine a world, with few people. The populaation of humans around 1 million. Your in a jungle, you wake up and you look around, nothing but vegetation, and your parents naked 0-o! You leave where you slept to see dead bodies on the ground. Not only that, but in the corner you see a dodo bird. [industralization didnt kill them because without technology there is no industry.] Later your hungry so you walk around, due to the fact you dont have weapons your a scavenger. You find a rotten dead pig and eat it. You suffer from salminella and die. the end. Lucky for us we have good lifes and if life ever seems bad just read this again and think about it!
