1. Dedicate one Shabbat as an eco-Shabbat. Hold services outside. Serve a Shabbat meal of organic food (on non-disposable dishes if possible). Organize a Shabbat afternoon walk and discuss Judaism and the environment. Lead a Torah study session on an environmental issue.

2. Celebrate Tu B'Shvat, Sukkot, Passover and Earth Day- holidays with built-in environmental messages. See http://www.coejl.org for a Tu B'Shvat haggadah and other program ideas.

3. Use recycled paper with at least 20% post-consumer content and recycle used paper. Also, be sure to make double-sided photocopies when possible. Use the backsides of drafts for faxes or as notepaper. And make sure recycling bins are located near the fax and copying machines.

4. Invite a speaker to address the connection between Judaism and the environment. You might co-sponsor this event with a campus environmental organization. Check out "COEJL's Guide to Speakers on Judaism and Ecology."

5. Organize hands-on action: clean up the area near your Hillel, a local park, river or beach.

6. Sponsor a hike. Study Jewish texts during a break, and pick up garbage along the trail.

7. Conduct an environmental audit of your Hillel (contact COEJL for an audit checklist). Determine how you can make the Hillel "institutional lifestyle" more environmentally responsible.

8. Participate in campus-wide and community-based environmental awareness activities. Participate in environmental coalitions, especially on campus, working to protect the local environment. Co-host an environmental fair with campus green groups and local environmental organizations.

9. Find out about the COEJL affiliate in your area. COEJL regional affiliates organize Jewish environmental holiday observances, educational programs, and action opportunities. It's a great opportunity to connect with other Jewish organizations in your community.

10. Stay in touch with COEJL. Sign up for COEJL Action (e-mail action alerts about important opportunities to advocate in Washington), and Kol-Chai (on-line discussion group), visit http://www.coejl.org.

1. BYOB - That is, bring your own bag. When you go food shopping, don't take plastic or paper bags from the cashier- bring your own re-usable canvas one.

2. Carry a mug with you so you don't have to drink from styrofoam or paper cups. P.S. You'll probably get a discount.

3. Be creative. Make rags out of old tee shirts and use them instead of paper towels when you clean. Use the backsides of photocopies for scratch paper. Donate used (and clean) plastic containers and egg cartons to local nursery schools for art projects.

4. Just say no to junk mail. Besides clogging up your mailbox, it is a huge waste of paper. Write Mail Preference Service and request your name, address, and phone number be deleted from all mailings and marketing lists. Be sure to write when you move, and be certain to sign and date your letter. Mail Preference Service, c/o Direct Mail Marketing Association, PO Box 9008, Farmingdale, NY 11735-9008.

5. Use your consumer power. Buy rechargable batteries for your Walkman and other appliances. Buy products in bulk when practical and products with as little packaging as possible. And of course, buy recycled and recyclable products.

6. Save energy and water. Check for drafts around your windows and if there are any, have Buildings and Grounds Staff fix them. Also, take note of drafts in hallways, bathrooms, and public space. Report any pipe leaks, leaky toilets or dripping faucets in the bathroom.

7. Instead of using conventional household cleaners that are often toxic, use safer earth-friendly products.

8. Don't forget the basics. Recycle newspapers, magazines, cans, and bottles.

9. Spend a little more to save later. Buy quality products that last, rather than ones that have to be regularly replaced.

10. You're on a roll, don't stop now. Visit http://www.coejl.org for more simple steps (as well as more complex ones) you can take to make a difference.
