Feeding the population

I believe that food should be produced in a way that supports biodiversity as well as the human population. A society in which all or most crops are produced with the idea of maintaining biodiversity on farmland would be ideal, including ideas such as a perennial, polyculture growing system and the inclusion of productive animals. With scaling and the question of will this method feed a growing population, I believe that part of the answer is in distribution management. IIRC ~50% of Canada's food goes to waste, ending up as compost or in the dump. We need a desperate change in how food is identified as edible (a lot of ugly food is thrown out) as well as a new way to distribute food within communities and around the world. Initiatives such as grocery stores that sell unappealing, but perfectly fine food are a present-day solution to the problem of that type of waste but should be more mainstream. For distribution, upscaling programs that buy food that is close to expiring or is unappealing to consumers at grocery stores and redistributing them to struggling people/communities would be a step in the right direction. This upscaling would most likely come from government funding, though if this already happens I'm not aware of it.
