I PREDICT......
That man will refine his use of materials to product products (example - producing can goods from sterilized waste products. The same would hold true of cars, airplanes, houses etc.
Secondarily we would develop adequate space travel to mine planets such as Mercury, Venus, Mars, the moons of Jupiter and the asteroid belt.
I envision Mercury (as well as Venus) having underground cities which use heat to generate refrigeration for underground miners.
Titan and Ganymede would also be viable options with the right technology.
I PREDICT......
We will be heavily taxed before being allowed to be buried in the earth (people are polution).
We will have to pay a recycle fee while alive to handle our remains at a future death.
We will have to pay a fee to exhume dead relatives remains that contaminate the Earth, and the land will be confiscated by government.
Homes will have to be painted in earth tones or green to blend in with the environment; otherwise be fined.
We will be restricted to no more than two motor vehicles per household; otherwise be heavily fined.
And so on...
My point being, it’s all about money and taxes. The environment being secondary.
