This article describes how community colleges, as educational institutions, play a central role in the sustainability movement and in the battle against climate change. Across the country, two-year institutions are creating sustainability programs, such as recycling garbage or composting food waste. They are building new green buildings, upgrading their facilities to be more energy-efficient, and installing new equipment, such as solar panels or wind turbines, to generate electricity. They also are increasing efforts to educate students about the environment and the need to protect it for future generations. At DeAnza College, educators not only are preparing students to live as good stewards of the natural world, they are also leading by example, creating a hands-on, organic learning environment that serves as a living, breathing reminder of the fragile state of the planet on which people live--and society's charge to protect it.
