Let's Stop Talking About Saving The Planet
We see what we hear.
When we hear "planet" or "Earth" we picture our large, friendly and rugged rock orbiting the sun.
How could we possibly hurt something so big?
When we hear the word environment or biosphere, we hear technical terms that some of us understand and many of us don't. People can understand the idea of "the life space." People can see that the thin strips of air and water painted onto this rock might be affected by what we dump into them, if we stop calling those places "the planet." The planet is going to continue orbiting the sun just fine.
It's the life space we need to worry about.
