I think the reason why humans are causing so much destruction is science. Science leads to technological advancement which leads to humans being overpowered relative to other organisms. Technology is behind every disaster caused by humans, and technology comes from the growing knowledge that comes from the scientific method. Hunting is only dangerous because of guns. Without guns, hunting could not result in extinction and indeed, not all animals could be hunted efficiently at all (rhinos come to mind). Casualties would be inevitable when trying to hunt lions, rhinos, etc… and humans would fear a lot of the animals that have been reduced to dangerously low numbers, which is how it should be.
Lions, Tigers, etc… should be above us in the food chain. I don’t want to get my face ripped off and subsequently eaten, but I could avoid that by respecting the territory of animals that are superior in combat. That is the next thing to discuss, territory. We demolish land and destroy ecosystems. Eventually nature will diminish and you wont be able to see anything but pavement and buildings. Humans will become extinct when the presence of plants and animals is vanquished. The earth has a maximum capacity for humans, and it is a shame that as humans come closer and closer to it that everything else has to be destroyed as well.
EDIT: It is also very sad that eventually the two most common types of animals will be house pets like dogs and cats that are the result of selective breeding for qualities that make animals increasingly dependent on humans for survival, and animals that are bred just to be killed, harvested, and eaten. Eventually animals will be nothing but poor weak little pets that can’t get food on their own and live to serve the emotional needs of humans, or helpless animals that are forced to do nothing but eat, drink, and sleep until they are all slaughtered and their bodies processed for food. Food chains won’t exist anymore. Animals need to be respected. I think we need to give away some of our land to animals.
