DAY4- The view from space PART1

How the land has changed, not only down on the ground but from way out in space. These are the latest images produced by the sharp eyes of a government satellite known as Landsat 7.
Darrel Williams works on the NASA(美國太空總署) Landsat 7 project, "We can see the condition shortly after the eruption, when just a huge area was totally deforested, literally burned off. Now, 15 years after the fact, we can see light, pinkish view, which says vegetation is growing back, it's starting to reforest."
Twenty-seven years of images have tracked the loss of rain forests in South America, as well as the clear-cutting of forests in th U.S. Northwest.
Darrel Williams , "Clear cut areas show up quite readily, and it shows we need to look at what's going on in our own back yard, as far as deforestation."
Landsat satellites have watched from space as glaciers have shrunk more than four miles over the past decade or so. This is a computer-animated view of Glacier Bay, Alaska, based on new images from Landsat 7.
