Green roofs are rooftops that are covered with vegetation. Though more expensive than conventional roofs, green roofs can reduce heating and cooling costs, and they can also filter pollution from air and rainwater. A concentration of green roofs in a city can even decrease the overall temperature of the surrounding area in the summer. Notable buildings with green roofs include Chicago City Hall and Rolls-Royce's headquarters in England. In what region have green roofs been in use for centuries?

In 1996, Shakur, an American rap star and actor, was fatally wounded in a drive-by shooting while stopped at a red light on the Las Vegas strip. He died six days later.

His killer has never been identified. However, some suspect that it was a man who had been in a public altercation with Shakur hours before the shooting—who?
