The demise of fossil foods will occur within 30 years as farmers run out of fossil inputs needed to produce food -- freshwater, fertile soils, fossil fuels and fossil agricultural chemicals. When the first fossil input become unavailable or unaffordable, our food supply ends. Abundant Agriculture offers a new and supplemental food supply using inputs that will not run out -- sunshine, CO2 and wastewater. Abundant Agriculture promises to relieve poverty and hunger for millions. We must act immediately to avoid a food cascade that will cause starvation for millions unless we move to recover, recycle and reuse energy and nutrients in human and animal waste streams.
