The phrase "going green" is usually interpreted as "oriented to the environment"?  Yet, the phrase "going green" needs interpretation every time it is used.  Does the phrase mean:

1.  be good to the environment?  If so, "how good" can humans be to the environment when other tasks face humanity in keeping humankind going?

2.  be good to plant life?  If so,  "how good can humans be to plant life" while human life is a struggle economically for much of the world today?

3.  the final question for discussion is "how green can be go today and still help humankind on its path of growth and development as individuals, cultures, and nations"?
