I think you can make an argument that all of those things are "natural," if you begin by positing that the evolution of humans was natural. Lot's of natural things make environmental and other changes quite naturally. Beaver's drown forests, leading eventually to things like spruce bogs. Various insects and birds bore holes in trees, often killing them. Taking what you need from your environment is what every living thing does, and humans are no different...only more creative about it.Is it really, pollution, deforestation, environmental destruction, ore extraction, oil drilling, war (not including early tribal war) well I could go on all day but you get the point (though I'm starting doubt, you will)
I also assumed you most probably know about 'the human impact on the natural environment'. Wrong. You think everything man does is natural
But our creativity and our intelligence...both also natural...make it at least possible that we might see what we are doing, and modify our own behaviours accordingly for the purpose of prolonging our ability to depend on our environment.
