He outlines the problems agribusiness have created such as pollution and huge public health issues. Actually, concentrating food production is not good for food security.
How to overcome shortages of food:
- Buy local to reduce energy costs. Use local farmers markets.
- Grow your own food in your garden. If you aren't able then look to accessing community gardens.
In the US during WW2 40% of crops grown by individuals. Agribusiness is not going to like this.
- Reduce food wastage which is very high.
- Cook your own meals. It is healthier and cheaper. And empowering.
