If you are seeking a once-in-a-lifetime experience that also supports conservation, Natural World Safaris has organized this philanthropic journey ($1,000,000) — a 12-trip package visiting 18 of the world's most endangered species across the world, including snow leopards, white rhinos, jaguars, and polar bears. Alternatively, there's always the gift of sustainability in the form of a pair of chickens ($18) or sheep ($80) via Oxfam to women in developing countries. These animals create a steady income stream — fertilizer, eggs, wool, and offspring — to those who need it most.
