Conservation of energy, not just as an abstract concept, but in that every time you fly in a plane, drive in a car, turn on the air conditioner, etc, you are using energy, which pollutes, and, while we use fossil fuels, contributes to the greenhouse effect. Most people seem to think their contribution doesn't count or is somehow less than everyone else's. Also, curiosity and appreciating the beauty of nature. These were two of my main motivations to get my PhD in physics. To me they are fundamental to science.
