The Universe contains about 100 billion galaxies each with at least 100 billion stars. Our galaxy, the Milky Way, contains our star, the Sun. Out of all
these stars in all these galaxies our Sun is the only one we know with a planet that supports life.
The earth and its living systems have evolved for five billion years . . . and now man and his technology have the power to destroy it all.
We also have the power to save it.
