The world is dangerous but we should also not forget people who live and lived without what we call modern technology and they did so pretty well. Many people have repeatedly chosen a lifestyle that is closer to hunter-gathering than anything else, even when agriculture and infrastructure were available as alternatives. They used and use different technologies, in their own ways highly sophisticated and with a form of social organization that is arguably more sustainable (it's not capitalism, for one thing). This is/was much more feasible in areas where there were lower populations and very large amounts of natural resources so that finding food and shelter and building tools etc was not particularly challenging. We live in a world we have damaged significantly. Far fewer fish, plants, frogs, etc. The bison massacred for genocide. The bedouin forced into factories and fields. Entire landscapes left to go fallow when they had been curated by humans despite Western impressions of "the wild".
