Have you ever heard of smog?

Have you ever heard of NOx?

Have you ever heard of acid rain?

Have you ever heard of ocean dead zones?

It's true enough that pure (meaning crystal dry and thus clear) CO2
doesn't by itself cause global warming, just like it doesn't cause the
bulk of any Venus greenhouse. However, our form of CO2 has been
rather particulate/sooty and wet as well as laced with NOx, as well as
having been deployed extensively above 10 km to start with, not to
mention the tonnes/sec of raw methane we've managed to release, plus
secondary methane and CO2.

Earth simply can not support 100 billion or even 10 billion hungry
plus energy and resource wasting humans, and stay exactly the same as
the garden of Eden.

Each and every tonne of new or replacement steel adds 2 tonnes of
dirty and wet CO2, and that's just at the primary foundry level of
production.
