All a personal choice. Isn’t that the mantra of the pro abortion folks? Irresponsible sex and kill a baby for convenience. That’s killing people and provides for the greatest reduction in population aside from world war. Both undesirable from my perspective. You think new options to facilitate your population reduction won’t come along, like corona?
BTW, how did this devolve from your original question about greener aircraft? I gave you a viable solution available and becoming more widespread today yet like the alarmists, nothing positive is ever acknowledged. Or are you just a troll stirring up the pot? At best you are a very naive individual with very little real world experience.
You can force other countries to do things to bend toward your will by imposing sanctions, boycotts, tariffs on imports or embargos. In America, we can have tougher immigration reform and border control. We can impose severe taxes on households that reproduce more than two children. We can give tax credits to households that adopt children in need of homes. We can give tax credits to adults who engage in sterilization as vasectomy and tube ligation.For ‘your own individual comfort’. Very scientific. The US has 332 million residents while the world is at 7.9 billion. Even if we sterilized every human in our nation it would have minimal impact on world population. Let me give you a hint where the bulk of the population lives. China and India. How do you propose we force them to cut back on their reproductive practices? Once again, idealism vs realism. A concept many have difficulty grasping.
The People's Republic of Covid recently lifted their one child per couple dictate to two children per couple. Since those people plan hundreds of years in advance I suspect personally that they are expecting the need for increased replacement rates because they are planning military options in the next 15-20 years...
I could be guessing wrong but I believe they protest too much that they do not have expansionist goals while they build military islands off their coastline and increasingly threaten Philippine and Japanese territories and the Republic of China...
Apparently you missed the main point of Doctor Kaku's predictions.
There will be no other intelligent life rising on Earth (or it is as doomed to extinction as we are) because the planet's days are numbered as surely as the supply of fossil fuels!
