That's pretty heavy. But... it's based off of materials that existed somewhere in this planet, no? At most, we've probably displaced a lot of that. Mining resources from the ground in what place and refining it to build a structure somewhere else. I'm not sure what to make of the oil we pull. Some of that turns into gas which is burned off to create heat and other gasses so some of that is displaced I'm sure.
Interesting food for thought here.
The weight of all buildings and everything else made by humans ( houses, streets, cars, factories and other buildings ) is 30 000 000 000 000 tons. That's 50 kilogram per square meter on the surface of our planet. This has been estimated by a group of scientists around Jan Zalasiewicz at the University of Leicester.

Valid point ! May be it is just that we move more and more material to the surface of the planet, like ants.
