Yes. The primary destruction we wreak resembles the effect of a plague of rodents. Human population has more than doubled since the Cuban Missile Crisis. One Russian submarine commander's humanity was all that prevented the consummation of that crisis from being a war fought not just with one uranium and one plutonium bomb of about 20 kilotons each, but hundreds of megatons of thermonuclear explosions. Unfortunately, if that had happened, we'd probably have also ruined the planet for the innocent forests, insects, dolphins, chimpanzees, other carnivores and their prey. So war is not the answer, even to getting rid of the this infestation of humans. Homo sapiens has to use his sapience, and humanity has to become globally humane.

I'd almost say that until we show that humans can treat our fellow-mortals (including forests) on this planet with more respect, we should be forbidden to mess up any others.

The Canadian Province of Ontario has made a huge improvement, since only 2003, in its air quality. They shut down about 4500 MWe of coal burning capacity, and brought up an equivalent amount of nuclear. They now get 58% of their electric energy from nuclear, 26% from hydro, 13% from gas, and 2% from wind. The capacity of "other efforts", with the possible exception of things like better insulated houses, and LED indoor lighting, maybe even bicycling if we could get the automobiles off the roads, is really very small compared with what a factory producing SMR breeder reactors would do.
