Early Specialization in Single Sport: A Dangerous Trend?

More and more parents are buying into the idea - one that many youth sports organizations and coaches actively promote - that their child will be unable to attain success or even make a high school or college team without specializing, playing on a select team, playing year round, and attending special sports camps in the summer. Many parents have come to believe that more (more teams, more practices, more intense and competitive games) and earlier (travel teams at age seven!) is somehow better.  How do you feel?  What do you think of this trend?  What do you think can be done to keep our kids from suffering the burnout, overuse injuries, and stress that early specialization and travel team seem to be causing?
