Not only is it a good thing for our environment, but planting trees may also reduce crime in your neighborhood.  Really!

If you want to ward off burglars, plant trees. You'll not only beautify your yard and do the environment a favor, but also discourage would-be thieves from breaking into your home, according to a study by the U.S. Forest Service. Less crime occurs in neighborhoods with big trees in the yards and next to the streets, while homes that have smaller trees have more crime. Large trees may be a signal to crooks that a neighborhood is well cared for, making it more likely criminals will be caught.
