When the first Earth Day was celebrated in 1970, millions of Americans--many of whom were college and university students--participated in an effort that sought to improve the quality of the environment and conserve natural resources. Since then, environmental studies programs have popped up throughout the nation, creating jobs for ecologists, politicians and other professionals whose career paths have them working directly on improving the environment. But today, there is a demand to "go green" and weave everything "sustainable" into the everyday lives of the people. This message is filtering down to other disciplines in higher education, not just environmental studies. Environmental and sustainability issues have permeated every level of academia, from art instruction to business courses. While community colleges are boosting training to meet the demand for skilled workers for "green" trade jobs, four-year institutions are promoting convergence of sustainable themes among departments, as well as integrating principles of sustainability into business courses. Being informed and inspired to create curriculum with sustainability in mind is key to improving the future of the environment, people's health and the world's economy.
