Addendum
Landscaping: Walking around the Virginia Tech campus you can tell that a lot of money is spent on landscaping and grounds keeping. I think keeping the campus and surrounding area looking neat and clean is a good thing, but honestly, do we really need to be completely ripping up and replanting every flower bed every season? Wouldn't it make more sense to plant a mixture of flowers that bloom at different times of the year instead? It seems incredibly wasteful, both in terms of resources and money, to pull up old plants and put in new ones several times a year. This goes for highway medians too. Ideally we should be planting some nice local flora that requires minimal maintenance.
