Document Summary
We can produce meat and dairy products more efficiently. Shift to more grain-efficient forms of protein. Beef from rangelands and pastures, not feedlots (bison) Eat less meat (eat lower on the food chain and slow population growth) Research on organic agriculture with human nutrition in mind. Improves soil fertility, reduces soil erosion, no pollution from pesticides, benefits wildlife such as bird and bats, increases biodiversity. Education of how organic agricultural systems work. Shouldn"t be about healthiness, should be about sustainability. Perennial polycultures have many advantages, including no tilling requirement, reduced erosion, less irrigation, and less chemical fertilizers. Permaculture a system of agricultural and social design principles centered around simulating or directly utilizing the patterns and features observed in natural ecosystems. Apply self-regulation and accept feedback: we need to discourage inappropriate activity to ensure that systems can continue to function well.
