What are some things that could be done to increase food production or eliminate food waste across the world?
I can think of several good ones but want to see what others have to say first.
Get rid of chemicals added to foods to increase appetite, this should reduce the amount we eat.
Work on the quality, not quantity of the food. Good quality is much more satisfying than cheap poor-quality foods.
Most sugar is unnecessary, fruit juice is much better in moderation, has enzymes in it for proper health.
Edible landscaping, why plant mostly trees that don't produce anything.
Teach children to garden, most are interested in their food.
Teach better farming methods around the world, it can increase production as can more productive varieties of vegetables & fruits. Vertical gardening is an option for vining vegetables.
