Writing on the Bathroom Walls

I may have mentioned that I enjoy eating at Whole Foods quite often. In case you haven't heard, I enjoy eating at Whole Foods quite often. In the men's bathroom there is writing on the walls. Its not what you think. Someone in their employ has painted three thought-provoking phrases of wisdom there:
1. To eat is a necessity, but to eat intelligently is an art.
2. Live and love each day as if it were your last.
3. Take care of the earth and she will take care of you.

Now the first two seem harmless enough, and I think that I would agree with them for the most part. However, that 3rd one seems to me to be leaning just a bit toward the new age type of thinking. What do you think?
