It's hip these days to be "green," but it ain't easy. (Sorry, Kermit.)

Speaking of animals, the Humane Society wants you to be green by using Earth Day, Tuesday, to kick off a season of backyard-wildlife awareness.

A company that makes glue wants you to use their product to fix things before you just chuck them in the local landfill.

The Princeton Review now gives colleges a "green rating," presumably to choose an institution that is more healthy and environmentally friendly than those other guys.

The group Rails-to-Trails Conservancy wants you to use unused railroad lines for recreation and commuting. Try one out on Earth Day and, if you dig it, park your pickup and help save the planet.

Save a forest. Cut back on noise pollution. Fight proposals for unsightly and intrusive power line corridors. Oppose drilling for oil in the Rockies. Go bird watching. Learn how to reduce your footprint on the environment. Call your congressmen and urge them to reverse global warming.

Overwhelmed, yet? Oh, we're just getting started.

If you must drive, get a hybrid. Help clean up a river. Take the train. Go fluorescent. Xeriscape. Use an electric lawn mower. Collect rainwater to irrigate your well-coifed lawn.

Reduce. Reuse. Recycle. There's a cool children's song about the three R's.

Join an environmental group. Need a list for Utah? There's Friends of Great Salt Lake, Great Salt Lake Audubon, High Uintas Preservation Council, Nature Conservancy of Utah, Red Rock Forests, Save Our Canyons, three chapters of the Sierra Club, Southern Utah Wilderness Alliance, Tread Lightly!, Utah Clean Cities Coalition, Utah Environmental Congress, Utah Open Lands, Utah Rivers Council and Utah Wilderness Coalition.

There's more groups, but newspaper ink is expensive and, well, not exactly "green."

Plant a tree or chain yourself to a giant sequoia. Be a green parent — we're not sure if singles are singled out on some Web site or in some club that promotes being green.

Even people who are getting married are being told they need to plan a "greener" wedding with eco-friendly choices for a greener planet by, for example, sending out announcements on recycled paper. How about this — maybe you could just e-mail everyone your wedding announcement.

If you're not using reusable grocery bags, wearing clothing that's made of recycled materials or if you're not doing at least one thing these days that you can label as "green," well, you're out of touch with what's happening.

If it seems like the Green Train is speeding up and attracting more passengers lately, then you've been paying attention. More information is available to more people via media of all types. A little star power doesn't hurt.
