US chicken companies pioneered restricting sleep to keep birds eating around the clock.
A new study (Li et al., 2026) recommends giving chickens just 2 hours of darkness nightly to maximize the time they spend eating. The study and photo are Chinese.
We know chickens have far better hapiness with 7–8 hours of darkness to sleep.
But they eat more and grow faster when they are sleep deprived.
It takes far less land to meet dietary needs with vegan food than with diets that include meat.
40% of worldwide grain production is used for animal feed. The calories obtained from eating the animal ~10% of what is used to feed the animal. We could fully replace meat, calorically, and free up more than a third of the land worldwide that is used for agriculture.
I’m not even vegan, but there is undeniably less environmental footprint to eating more plants and less meat.
