Clinton touched on a series of issues impacting the world, including the environment. One way that retail developers can help improve conditions is by constructing environmentally friendly developments, he says.

One feature that may define shopping centers of the future is an area where people will be able to recharge their electric cars. Landlords can also make sure that their projects are close to other alternative fuel sources, Clinton said.

If something isn't done to change the effects that emissions have on the atmosphere, dire events could occur, he said. Global warming may melt ice caps, leading to a larger ocean. In 50 years, Clinton predicted, 50 feet of Manhattan could be under water and many East-Coast cities might be flooded.
