ABOUT THE TOPIC:</b> </font><font size=3>The global population at present

is seven billion. At current rates of growth, we will reach 9 billion by

2030. We have been adding population in large part because of what has

been deemed the green revolution, the ability of science to grow huge amounts

of food, (mostly cereals such as rice, wheat and corn). But the green revolution,

in turn, is based on cheap, plentiful supplies of water (for irrigation),

energy (for fertilizer) and a stable climate (monoculture). Dr. Zizka will

discuss how increasing CO2 and climate change increase the vulnerability

of the global food supply and propose some solutions that could increase

the resiliency of global agriculture. <br>

SUPPORT THIS CAFÉ:</b></font><font size=3> The Ballston Science and Technology
