But I do believe it contains some illusion in that different materials have different impacts on the environment. For instance, aggregates and parts of concrete and asphalt are way less damaging than cements, tar, bricks, plastics, metals … all requiring more transformation which are more damaging for the environment.
So the problem is not the mass itself but rather the impact on the environment.
For those who want the tl;dr:
Thanks. This is a nice and striking image.
