> I read somewhere direct efficiency of most grain crops in sun energy conversion into calories is 1% This is why I’m in favour of turning farmland into suburbs/exurbs. As you cover your roof in solar panels and plant a few trees, you’re collecting more energy than the farmland did before. And if you’re like me, using most of the backyard as pretty high intensity agriculture and food scrap management (and if I could get away with it, some fertilizer I usually flush to the city for processing…). The average flower garden has more biodiversity than any corn or wheat field.
