The plants use energy from the sun to turn carbon dioxide from the air into edible calories. When our animal bodies “burn” the food we eat, that turns it back to carbon dioxide, which we exhale.

The energy input is the sun, and most of the calories come from the air (carbon dioxide). Given so much external input, harvesting from a plot without reducing soil fertility is totally possible. With nitrogen-fixing crops (soybeans being the poster child), even the nitrogen fertilizer comes from the air.
It used to be more true, when straight chlorine was what was used. Now most municipalities use chloramine, which is more stable. Most plants don’t care, but it’s an issue for fish, so there are “water conditioner” products for aquariums that remove both chlorine and chloramine.

To an extent, this is already happening. I work in manufacturing, and the last couple of years there was more demand for our product than our factories were physically capable of producing, and prices were raised to weed out the number of customer orders to what we could handle. Projections for this year are for softened demand, and sales expects to have to offer significant price cuts to keep enough orders for our manufacturing lines to stay busy.
Collective “we have enough stuff and will buy less” at work.
Or hold on for two years. At least in the US, the non-payout for suicide is only allowed the first two years of the policy.
You are probably being sarcastic, but for those who haven’t come across it - operating rooms are often called theaters.
Girls are made to feel unwelcome in chess environments at a very young age. Of course once many drop out because of cultural pressure, the remaining small sample size will have less spread than the larger population of men who have been made welcome in chess environments their whole lives.
I might end up wanting a video, but there is so much low-quality content in search results. I can click into and out of six bad sets of written instructions in the time it takes me to watch one video far enough through to realize it doesn’t answer my question. Please, search engines, place more written instructions higher up.
It’s not just visual deepfakes, either. There are large language models out there now that can be trained on a person’s writings to chat “in their style”. Having such a model act like an acquaintance but prompted to express love and/or NSFW fantasies is a similar moral area to the deepfakes visual porn.
Modern industrial farming is not sustainable for the next hundred years, no, but there are a lot of levers to work to transform it into something that will reliably feed future generations.
One lever is amount and kind of meat in the average diet. It takes something like seven pounds of grain to make one pound of beef. Modern chicken breeds are amazingly efficient at converting feed grain to chicken meat, but even they are something like two pounds in to one pound out. Reducing the percent of meat in our diets would make our food go significantly further.
