Yosemite National Park USA - A MEDC case study of a tourist area requiring sustainable management

Here is an 8 minute video with a suspect choice of soundtrack. However it is a decent tour of the area, given that we are 100% guaranteed not to have a school trip here. You will have to visit the site as they've decided to block embedding into blogs.

When watching the video, some points to consider:
Why would people want to come here?
Would there be peak spots where lots of visitors would go at once?
What issues might a large number of visitors cause?
Who is interested in protecting this National Park?
How might they start to help protect popular areas (the 'honeypots')
