What’s your opinion on this?
I’m leaning more toward 1 trillion - YMMV.
Much more than past and most present estimates of how many persons the earth can support, and with AGM helping.
"The Food & People Dilemma" written by Georg Borgstrom..."By 1985, when the world's population will approach 5 billion, nearly three-quarters of the people will live in food-deficient countries," he predicted. - https://www.oklahoman.com/story/news/1985/01/13/starvation-result-of-world-overpopulation/62777711007/
In 1798, Rev. Thomas Robert Malthus predicted that population would outrun food supply on the assumption that human numbers would increase at a geometric rate while food would be limited to arithmetic increases. Then, in 1968, Stanford University professor Paul R. Ehrlich issued a similar warning in his book The Population Bomb, in which he predicted that hundreds of millions of people would die of starvation in the 1970s and 1980s.
Some, like Cornell University ecology and agriculture professor David Pimentel, contend that the Earth has already passed that point. Citing high malnutrition rates in the world, Pimentel estimates that the Earth’s carrying capacity—providing a quality life for all inhabitants—would appear to be about 2 billion. - https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1280423/
Jan 31, 2001 — If the entire world population would assume the current consumption levels, the limit to the world population would be only 7.34 billion people. - https://archive.unu.edu/unupress/unupbooks/uu03pe/uu03pe0c.htm
In his 1995 Science paper, 23 Cohen computed the median of the high estimates and the median of the low estimates. The result was a range of medians from 7.7 to 12 billion people. ... Using standards of living lower than the current North American average, estimates of carrying capacity using energy as a metric range from 1 to 3 billion people. This is less than half of the current global population.Sep 13, 2002. - https://faculty.washington.edu/rturner1/Sustainability/Bibliography/docs/Human_Carrying_Capacity_of_Earth.pdf
, Oct 11, 2011 — Many scientists think Earth has a maximum carrying capacity of 9 billion to 10 billion people. - https://faculty.washington.edu/rturner1/Sustainability/Bibliography/docs/Human_Carrying_Capacity_of_Earth.pdf

However, the sore judgements of Revelation are yet to come, and we of the church are overall not ready.
