Change happens by listening and then starting a dialogue with the people who are doing something you don't believe is right. - Jane Goodall

We’re not really a very intelligent species when we destroy our home.

Let us learn to live in harmony with each other — between the people of different nations, cultures, and religions, and between us and Mother Earth. We're trying to grow a family of young people who move out into the world with shared values, who understand that although we may look different, although we may have different-colored skin, have different cultures, or wear different clothes — if we're sad, we cry, and the tears are the same. If we're happy, we laugh, and the laughter is the same. And within each of us, wherever we are, beats the same human heart.

The most important thing is to actually think about what you do. To become aware and actually think about the effect of what you do on the environment and on society. That's key, and that underlies everything else.
