Science in Action

With the growth of the human population the impact on the environment is inevitable, but until recently we would hear about it and maybe see before an after pictures.  Now NASA has put together time-lapse videos showing the impact man can have on the environment, some bad and some good.  The videos are hosted on YouTube, but Wired has provided some basic background information in case you are interested.  These could make for some very powerful discussions in classrooms across the country.
