An Example of Why Humankind May Not Be Able To Save Itself from Extinction.

California has decided to ban gasoline-powered lawn mowers and leaf blowers. Besides being noisy, smelly and, especially in the case of leaf blowers, generally irksome, they emit a tremendous amount of toxic pollution and greenhouse emissions. This is the kind of reform that should have been instituted throughout the world years ago, but won’t be replicated in most jurisdictions for a long time, if ever, which is another example of how humankind seems unable to act collectively and rationally to save itself.
