One apparent damage is how literally like how relevant Quora answers I have come across here have said.
By using technology.
We have literally “scarred the Earth” like we tunnel through mountains either because we wanted to build a rail line through it or get to that section of rich mining veins.
We have literally left our “mark” there which is like saying “humanity was here”. Lol.
There are probably a lot others but I wanna point out the one thing that really stood out to me.
Ancient cultures also did this but not to the scale we modern humans did.
And all of it was possible because of technology and advancements within it.
