If the other 25 were such glorious successes why do we need a 26th? Hadn't we sorted the problem? Well, no, we played at it.
In 1992, in Rio, we started this farce and nothing has substantially changed. Except that back then the global population was about 5.5bn; it is now 7.8bn - a rise of almost 50%. All those (extra) people need food, water, shelter, clothes, education, medicines, services....but forget all that. Heat pumps (aircon) electric cars, and Quorn burgers will save us.
When I was born, in 1953, the global population was 2.6bn, it is now three times that. Sod the climate, we are well past the tipping point in that regard due to lead times of what the planet can sustain, or help us, even in the short to medium term. Think of the various environments.
What we need is a proper pandemic. If it does in the business peeps, bankers and economists and their dream of eternal economic growth and leaves the rest alone, so much the better.
