"Green" is not only a simple adjective to describe a lime, an olive, or a piece of jade's color right now; or a noun to illustrate a color which is a mixture of yellow and blue; the color of Shrek or the color of New York Jets. The word, green, becomes a verb to express that someone is doing something which can protect the environment, as well as a noun to categorize someone who has capability to care for the environment. Nowadays, furthermore, the word represents an investment and a future trend in the business field. When you open any investment guides or business magazines you found on streets, the "Green Industry" always stands as the hot topic in their suggested list. However, I think to achieve "Green" in the United States will be a long journey.
