|Full reason for rating.Research into alternate food sources|
Research ways to reduce the resource demands to produce food, e.g. stop farming animals and replace animal protein with alternate protein like soya and processed insects like meal worms and crickets. These alternate foods might also introduce new diseases because of malnutrition, which might not be immediately apparent.

These alternate food sources will still need to be `farmed` and processed and will eventually not be able to feed the world population if the population keeps growing. These alternate food sources will also have their own resource requirements, which might have all sorts of other impacts on the environment.
