A lot of our human destruction is from our point of view. Every species including ours eventually will come to some sort of balance with its environment. This balance generally comes in cycles. Most of human activities are an attempt to circumvent these natural cycles.
One such cycle is the cycle that runs between the fox and the rabbit in the US and Canada. The rabbit is so successful in one part of the cycle so that they increase to the point that the foxes have a very easy life. The rabbits don't get enough to eat and are weakend and easy prey. The foxes eat well and have many babies. next year there are so many foxes that most of the rabbits get eaten. This leaves more food for the surviving rabbits. Meanwhile the foxes are so thick that the worms, viruses, and starvation kill off a lot of them. Then the rabbit population rebounds and the cycle begins anew.
When you transfer this to humans you can see evidence of the cycle again. Humanity was in a fair balance for thousands of years. Sometimes they starved, sometimes sicknesses and poor nutrition served as a check on their numbers. Then some clown taught the Jews to wash their hands. Uh-O! That was a technological improvement that allowed cities and towns which heralded in agriculture. The the laws of Malthus took over again. Famines in China and India kept down the population. Tribal warfare in the Americas helped slow down population growth for several thousands of years. Then another clown invented the plow and the horse collar. This allowed a density human density to occur that allowed for plagues and smallpox. This worked for a couple hundred years. Then technology reared its head again. Vaccinations and artificial farming methods are staving off the cycle for now. World wars and cultural wars such as the Viet-Nam, Korean, and Boer wars helped some. The troubles in the Sudan are killing many that would otherwise starve as their resources run out. Abortion in the U.S. and Europe are killing a hundred thousand or so a year.
So humans also have a natural equilibrium. Humans are also the only animal potentially able to understand this. The only point open to debate is at what living standard do we wish to maintain this equilibrium. It will happen whether we do anything or not. Malthus was a mathmetician or rather perhaps a philosopher who understood arithmetic.
As a species humans are a sucessful one. The jury is still out on whether they , as a species are an intelligent one or whether we will continue to be subject to natural cycles?
