Each December 31 of the years listedin the answers I'll ask the best available free version of chat gpt, or the next best publicly available alternative in case chat gpt is no longer available, on that day to:

1. List all countries that completely ban single use plastic bags

2. Provide the population size of all of these countries

3. Sum the population sizes listed before

4. Provide the estimated world Population today

5. Divide answer 3 by answer 4, yes in case >0.8

I'll extend the deadline according to the years provided as possible answers, yet I'll resolve early as soon as the criteria above are met.
