Re: Greta Thunberg ... again
I am going to get clonked for this, but I am sick to death of awareness movements that really don't do anything but incline the advocates (not "activists" which is an oft-used misnomer for people who are truly exacting change) to pat themselves on the back and never really do anything helpful.
As OGF and others have said, why is it that people think that entrepreneurs, scientists, companies, and governments aren't trying?
It's been well-observed here that the problems of resources, along with nitrogen and carbon fixation have more to do with population than anything else. We are headed to nine billion by 2050. If you have a dinner party and two hundred people show up, you are going to run out of everything and sooner or later, some nasty arguments will ensue.
The answer, as it has been mentioned, is birth control, which should be given out like candy in every country on the planet. That's simply the most elegant, humane, and economic solution to anthropogenic climate change.
Climate change, however is not anywhere the biggest problem. What we should be working against are the horrors of a planet with 14 billion people in which wars, famines, and mass die-offs from disease will cull the numbers.
As for Greta, good for her for finding her voice. It can't do any harm, but I doubt all this will do much good (see above). People with Aspergers are often extremely bright and bring new paradigms to old problems. However, I am likewise concerned and hope she is getting medical support. Her meteoric fame could be very debilitating in the long run. I too think fear that she being used an manipulated - and may face personal, hurtful backlash for which she will be ill-prepared.
I expect that the story of man will very short-lived on the environmental scale having used up resources and causing this massive 6th Extinction period. Either we curb our numbers through birth control or nature will. Nature never tolerates imbalance and could care less about the protests of man.
