For instance, the number of bushels of corn that can be grown per acre has increased dramatically in the last 100 years. Still, there is an ultimate limit to the amount of corn that can be grown per acre because there is only so much sunlight per acre, and it is the energy from the sun that causes corn to grow.
Innovative technologies can sometimes be double-edged swords. Industrial-chemical agriculture is one of the largest sources of greenhouse gas emissions. The increase in crop production in some locations has required massive amounts of irrigation, which is causing water tables to fall. What will happen to food production in those areas when the wells run dry?
