Many of the world's vacation destinations are disappearing.

Global warming and human activity take a heavy toll on some of our most popular tourist attractions. Some endangered sites may be gone before we have a chance to see them. Should we travel to these fragile places, or will that make the problem worse? The Hipsters examine a few of these destinations and discuss the benefits and drawbacks of tourism.

Beer: There's caffeine in our beer! The latest release from MateVeza is the flavorful, full-bodied Organic Yerba Mate IPA. Stimulating, to say the least. Want to go for a jog?

Chocolate: Fonda in Missouri reclaims her title as Our Favorite Listener by sending a delicious Art Bar Dark Chocolate with Cocoa Nibs. They give 10% of their profits to art education, thereby offsetting our negative cultural impact.

Finds:

• Val's Favorite Thing! Now that her son is becoming a vegetarian, Val is getting a lot of use out of her Tortilla Press. Wholesome homemade corn tortillas wrap around those beans and veggies for an easy meal on-the-go, and clean-up is a snap.
• Jam session. San Francisco's Yes, We Can is a community canning project preserving the flavors of summer. Try it in your area...we hope you're jammin' too!

• License to ill. A quarter of "natural" supplements are not living up to their labels, according to ConsumerLab. If you've been buying Hoodia, you may be Scroodia!
• Who gnu? Large animal migrations in Africa are on the decline. Researchers say human development is to blame.

Book 'em! The next time you're purging books from your shelves, consider donating them to a prison. Their libraries are grossly under-inventoried and they can always use textbooks or any other educational material. The book most requested by inmates? A dictionary!

Some of the world's most glorious sights may not survive through this century. Should you travel to see them while you still can, or will that just worsen their plight? Learn about some of these endangered destinations and how to minimize your impact.

• Global warming has left few places untouched. Glacier National Park, the Great Barrier Reef, Venice and the Maldives are among its victims.

• Chris in Montana sends congrats ahead of our 4th anniversary. He interviewed us in 2006 for Podcast User magazine and still thinks we're rock stars after all these years!
