Vacant lots and undeveloped Government Land

Vacant lots and undeveloped lands are everywhere . Especially here in America. With poverty and homeless families losing homes . People need to feed their families and using lands even on a temporary basis could feed all our nations poor. Myself and every Gardener/Farmer I know would gladly give free herb , fruit , and veggie seeds. Or sell them to raise money for shelters that want to grow an abundance of food.
