Composting is important but it's not the answer to the mysteries of the the cosmos nor will it save your life if you've got cancer.
Take my mom. An old-time hippie, bead wearing, organic goddess of a Woman. She believed, and rightly so, that it should be a religion to eat organic foods provided by local farmers. She believed that following this spiritual path would make her years secure.
Then she got cancer. She had no health insurance.
Cruel and stupid people might argue that somehow she brought it on herself, that she had some flaw in her cosmic awareness. Truth was that she did everything "right." And once she had cancer, she tried all the healthy cures. She still needed conventional treatment which was hard to get without insurance. She got some of it, but not all of it. She died. She might have lived with health insurance. Certainly with insurance she would have had yearly checkups and would have caught the cancer early.
Compost by all means. Worship the Earth. Drive a Prius. Ride your bike. Worship Kali. But saving the Earth is also saving ourselves.
Please. Fight for Universal Health Care. Don't think you won't need it because you're young and happy.
