Recycle old abandoned shopping centers into green areas.

Dear Obama Administration,
My name is Nicholas Ose and I live in a developing suburban town called Crofton, Maryland. Which is like most towns in the United States considering the extensive expansion of new buildings. However, due to the new mega-shopping centers businesses have been pulling out of the older shopping centers leaving vacant buildings or altogether abandoning stores. This, is not just happening in my home state of Maryland. But, places all around the country. I want to propose that the United States should take these abandoned buildings and turn them back into little sets of woods and shrubbery again. This will benefit the citizen's of the U.S by creating new job opportunities as well as helping the environment. By reducing water run off and CO2 emissions.
