Antarctica: A windswept wasteland at the edge of the world, enveloped by snow and ice, showered by ultraviolet rays that pour through a growing hole in the ozone, home of penguins, base to McMurdo Research Station and its family of scientists. About 1,000 women and men live at McMurdo Research Station during the Antarctic summer. Because shipping things in and out of Antarctica is so expensive, they closely monitor their trash: what can be recycled and what cannot, and how to reduce the total amount. McMurdo residents recycle 61 percent of their solid waste.
