08:11, 28 September 2022 Elie talk contribs created page Zoning (Created page with "Zoning means ''designating different areas for different purposes''. Parts of a city (or town) may be zoned as residential, commercial, or industrial. There are good reasons for doing this, but it can also be done wrong. ==Harmful zoning laws== Some suburbs have nothing but houses. People end up having to drive excessively just for basic things like groceries, school, work, or recreation. This makes life unnecessarily expensive, and is harmful to the en...")

16:17, 26 September 2022 Elie talk contribs created page Biomass waste (Created page with "''Biomass waste'' refers to the ''parts of food crops'' that humans '''can't''' eat. This material is mostly fibre (cellulose). '''Examples:''' * banana leaves * peanut shells * coconut shells * empty corn cobs with no kernels. * straw '''Abundance:''' * Production is roughly equal to food production, because about half of the average food crop is biomass waste (the other half is food). * This page needs more precise numbers. '''Uses:''' # All biomass waste can be...")
20:48, 21 September 2022 Elie talk contribs created page Feed efficiency (Created page with "Farm animals eat, and they also produce food. Feed efficiency refers to the ratio of ''output (food)'' per ''input (feed)''. There are a few ways to quantify outputs and inputs, such as * total mass * dry mass * calories * protein Within each of those, one might also specify whether we're talking about * ''all'' material, or * just the proportion that is ''human-edible'' Lastly, we could specify whether the inputs & outputs are * ''over the full lifetime'' of the animal...")

There are 3 main types of corn: * Sweet corn (1% of all corn grown in the USA) ** This is the ''corn on the cob'' that people are most familiar with. * Field corn (98% of all corn grown in the USA) ** Used for making corn chips, corn muffins, and other starchy foods. ** Can be converted into sugars (high fructose corn syrup). ** Also used as animal feed. ** Sometimes referred to as "dent corn". * Popcorn (1% of a...")
08:23, 1 September 2022 Elie talk contribs created page Underutilized foodstuffs (Created page with "Underutilized foodstuffs include anything abundant that isn't generally eaten by humans but could be - and could provide valuble nutrients. Ongoing list: * molasses (people do eat it, but far more of it is produced than consumed by humans). {{x|This is because it's a byproduct of something more widely consumed: sugar.
