Canadian astronaut sees "human destruction"

Speaking from space, Canadian astronaut Robert Thirsk urged Canada to consider the future of space exploration and shared his own insight gleaned from orbit. "Most of the time when I look out the window I’m in awe," he says. "But there are some effects of the human destruction of the Earth as well." Thirsk was last in space in 1996 and says changes to Earth’s geography since then are seemingly apparent. "This is probably just a perception, but I just have the feeling that the glaciers are melting, the snow capping the mountains is less than it was 12 years ago when I saw it last time," he says. "That saddens me a little bit."
