Some great new information layers are waiting to be discovered in Google Earth. My favourite so far is the UNEP Atlas of our Changing Environment (under the Featured Content tab.)
Fortuitously, overlays for the 3 Gorges dam have appeared at the exact moment I need to teach the case study to my GCSE group!
Thanks as usual to Google Earth blog!
Update:
There’s been a couple of upgrades to Google Earth in the past few days. I’ve noticed a big increase in speed and stability with the latest version 4 beta. Download from here.


Google Earth is getting significantly better with each release I’m finding. Totally agreed.
