long term plan
1) increasing arable land, by improving crop yields and the efforts of #2 and #3
2) decreasing un-arable land, by finding methods of salt removal, and nutritive addition.
3) developing self contained plant structures, both large and small to increase the surface area of arable land. Such as farm-scrapers, and self contained corn, potato, wheat, tomato pots that accommodating one plant for 100’s of harvest cycles.
Without people we can not increase anything. Food is the one thing that will limit humanities growth the most. Increasing food production will increase all other forms of production and efforts.
