Stop the waste & feed those who need it

With so much food wasted/unsold and then destroyed or made unfit for consumption by being covered in bleach etc. why not give it to food banks & charities to feed those who have been left in a position that they are unable to feed themselves. Anything that's past human consumption give to farms instead of filling landfill sites with it
