A great place to park a tree Philadelphia Inquirer 06/09/2010:
Parks and Recreation Commissioner Michael DiBerardinis has said he wants 300,000 more trees planted in Philadelphia by 2015, and an expansion of the city's canopy from 15 percent to 30 percent over the next two decades.
Here's a good place to start: parking lots.
Surface parking lots cover an enormous amount of land in urban areas, ranging from 18 percent in New York City to more than 80 percent in Los Angeles. Philadelphia and its suburbs have thousands of asphalted acres dedicated solely to cars.
Because of the need to provide parking for cars at every possible destination, we've created far more parking spaces than we have cars. That means most parking spaces are empty most of the time - an enormous waste of space.
