Over the years, various posts have pointed out the usefullness of satellites for detecting human caused environmental damage. I think a thread to collect all of those existing and future posts showing destructive environmental damage to our planet would be a good idea. For that matter, positive progress should also be shown, where it exists. If you have posted concerning the environment, or if you know of a post about this subject, link to it here. Instead of Re:..........., use a descriptive title for ease of searching. The same goes for new posts that you might create. A single thread should be much more powerful than scattered reports.
