Not super related, but one interesting thing mentioned in the article is that the population will increase from 8 billion to 10 billion by 2050, "increasing global food demand by 50%." Why would a 25% increase in population cause a 50% increase in food demand?
- tantalor 5y agoFood waste. Half of the food grown is thrown out instead of eaten.
- halpert 5y agoThat doesn't make sense, unless the amount of food waste, measured as a percentage of total food, increases as the total amount of food produced increases.

- pugworthy 5y agoI've no facts to back that up, but my bet is that a) this is true in well off countries, and b) not true in non-well off countries.
- tasha0663 5y agoI always wonder what the ideal amount of food waste is supposed to be. Zero is a post apocalyptic hellscape.
- ggm 5y agoIn primary production most things you don't consume yourself have either to earn income or cost you money to dispose of, and suddenly zero waste is a big win. Pig slurry has massive costs associated either with remediation of water or cartage. If you can make methane, drive a generator or heat or cool something or run pumps, and then have (in disease terms) sterile and nutrient rich water to use.. it's better. Ploughing in your unsellable fruit is said to be heartbreaking. Suicide in farmers is high. Growing less and getting a better price for it might be better than growing more but losing half the produce to skin taint or bruising. Less inputs, more value per acre worked.
- eco 5y agoI remember reading a while back that food waste was roughly similar between developed and undeveloped countries. The reason for the waste was different though. In developed countries it was consumers throwing out uneating food and in undeveloped countries it was due to poor storage environment before the food got to the consumer.
- dane-pgp 5y agoWhen I looked into the figures, a large proportion (a majority?) of the "waste" occurred before the consumer even bought the food, so although the statistic is designed to shame people for their "wasteful" behaviour, the problem can't actually be substantially fixed without forcing people to eat lower quality "food" or otherwise reducing the food options available.
- riffraff 5y agoisn't lower quality food employed in different ways? E.g. recycled as animal food.
- jhgb 5y agoRising living standards, for one?
- Game_Ender 5y agoIt could be increased standard of food as the world develops. More meat for consumption would increase the amount of food grown to raise the animals we slaughter for meat even with a static population.
- halpert 5y agoThat would definitely make sense. Something about the wording made it seem like the increasing population specifically was responsible for the increase in food demand, but it was probably an editing oversight.

- AnimalMuppet 5y agoThere are a lot of people who want to eat better than they currently do.
- iam-TJ 5y agoIncreased consumption per-person as more people have improved economic circumstances. See "How to Sustainably Feed 10 Billion People by 2050, in 21 Charts" [0]. "There is a big shortfall between the amount of food we produce today and the amount needed to feed everyone in 2050. There will be nearly 10 billion people on Earth by 2050—about 3 billion more mouths to feed than there were in 2010. As incomes rise, people will increasingly consume more resource-intensive, animal-based foods."
