When it comes to giving away their $60 billion, Inside Philanthropy finds Mars family appears to have a soft, nougat-y center for wildlife and conservation.

"We've been doing some digging on Mars heirs Jacqueline, Forrest, and John Mars. It's not that we want a free lifetime supply of M&Ms, though we wouldn't be opposed. It's that the three grandchildren of Mars founder Frank C. Mars have an enormous $60 billion fortune to their names, and their philanthropy to date has barely gotten started in comparison to their net worth. One area of philanthropic interest for the Mars heirs is supporting animals and wildlife." -- Ade Adeniji, Inside Philanthropy
