Seattle filmmaker Ethan Steinman will be on hand for a Q&A when Whitman shows his film "Glacial Balance."
"Glacial Balance" is a journey along the spine of the Andes, from Colombia to Argentina, getting to know the individuals and lives of those who are first affected by the dwindling tropical glacier reserve.
According to environmental activist Bill McKibben:
"Few things are changing as fast on our home planet as the cryosphere--the frozen plortion of the earth's surface, which is melting quickly. And nowhere faster or with more grievous effect than along the Andes, as this piercing film makes clear!"
