Know. Care. Consider
Know
What are the possibilities? Educate yourself on the possibilities that are available for energy reduction, and sustainable living. This is the knowing. Know what the possibilities are.
Care
What impact do you have on the environment? What is the footprint that you are leaving? Care enough about the planet, our resources to want to consume less and give more.
Consider
How can I integrate this into my lifestyle? To what degree will I live a sustainable lifestyle? Consider how changing to energy efficient light bulbs or how creating a homestead will help for those who come after you. Consider the effect your life has on the environment and if you care enough to do something more about it.
