The underlying theme of TrekEarth is learning more about the world through photography. TrekEarth fosters this by allowing photographers to display their work grouped by regions in a supportive and orderly environment. This is accomplished by an easy-to-use system which encourages people to critique each other's work. Integrated with this system are forums designed to encourage discussion about specific photos, countries, and general topics. Since TrekEarth is globally oriented, it is completely multilingual capable, allowing for the widest audience possible. Ultimately, TrekEarth depends on the civility, honesty and participation of its members.
