Taking in the sights, taking pictures, taking a bus, taking your time ... no wonder they call it taking a vacation. Instead of always taking something away when you travel, why not give something back? There's no better cultural immersion than to earn respect by working side by side with locals. The options are endless; pick one you're passionate about and leave the land, animals or people better off than before you arrived. The bonus is you may find you take away more from your travel than ever before.
