Maybe if we start simple then we can grow.
We being the general population.If we start with the simple idea of those who own land whether fom a 1\4 of an acre to more have the family go out in the back yard and plant a few herbs, vegetable and fruit tree we can then begin to feed our selves.
Next the communuty can have a small common where individuals can go and voulenteer their time doing agriculture.
It would be a nice place to make friends while helping the poor and malnurished.
