e earth's population will increase by 150,000 people per day for the next 40 years, which means the world will need to increase food production by 70% in that same period---even as the relative number of acres that can be cultivated globally shrinks. To feed our increasing numbers, we will need to nd ways to grow more food per acre. By 2030, the world will consume 60% more energy than today. And while the demand for energy grows, the supply of fossil fuels will not. Deep expertise in microbiology, fermentation, polymer science and electrochemistry will help make possible the transition from fossil fuels to more sustainable alternatives.
