The human population is growing. The land available for farming and ranching is decreasing. In the last 40 years, 33% of the arable land has been lost to pollution and erosion. In the next 35 years, we are expected to need 50% more food. Supply is decreasing and demand is increasing. Food productivity may increase and may include techniques that don’t require arable land (fish farms, hydroponics, etc.); but the trend suggests escalating food prices, more refugees, and greater instability and strife.
