You can develop eco-friendly habits to help you use less and make the most of what you have. Turn off lights in empty rooms and use a programmable thermostat so you're only heating or cooling your home when it's occupied (see References 2). Businesses can also institute such practices, in addition to bigger initiatives, such as company-wide recycling programs to conserve natural resources and telecommuting for employees, which decreases air pollution and fuel consumption by eliminating daily travel to work.
