At first, I was going to question why environmentalists don't go batshit crazy over these launches. But then, I did some quick research and found that, in comparison, automobile emissions dominate global transport emissions by orders of magnitude.

Obviously, there are many factors, but I've questioned this for decades, and the reality surprised me.
