Alanna Mitchell, an environmental reporter, hopscotches across the globe in this report from some of the world's most interesting and beleaguered places: Iceland, Galapagos, Bank's Island in the Canadian Arctic, Madagascar, Suriname, the Azraq Oasis in Jordan. She deftly combines the personal, political and scientific in this engaging eco-logue, largely avoiding the unavoidable gloom and doom in favor of wonder and information.  (TVL66, $25.00)
