By the way, do you gentlebeings know how we almost destroyed the ozone layer by accident?
How we have the early environmental protesters, a well-funded and competent U.S. federal scientific apparatus, and the 1973 energy crisis to thank that we even learned of the problem before it was too late?

The long-term unintended effects of novel synthetic compounds are quite high in my list of potentially serious risks to the well-being and viability of human civilisation.
It is extremely difficult to reliably assess even single chemicals, and almost impossible to predict their interactions.

As in, had a few things gone differently, we might now need wraparound sun goggles to venture outside.
Not an outlandish prediction by any means! Just take a look at how airspeed records had increased by then.
Because airlines and airplane manufactures everywhere believed that passenger jets of the future would be supersonic.
So much so that Boeing engineers thought the 747 would be the last of their subsonic planes.
So they raised the flight deck into the "hump" above the cargo area, permitting a nose door to be installed.
But I digress.
And they, alongside concerned scientists, started asking questions.
Such as, what would be the environmental impact of the proposed fleets of SSTs?
Here's a view from the Concorde. You can see the sky is black despite the Sun, and the Earth's curvature can almost be seen.
So the SSTs not only deposit a lot of combustion products into the atmosphere: they deposit them high up.
