� AFRICA: Elizabeth Vargas will report from an eco-lodge reserve near the Kruger wildlife area in South Africa to show how conservation can save species.

� EUROPE: Chris Cuomo will be in the city of lights, Paris, reporting on how people can conserve power and ways that science could help take carbon dioxide out of the air.

� SOUTH AMERICA: John Qui�ones will be in the Brazilian rain forest reporting on how conservation groups are working to replant the rain forest and how these forests can be worth more as a standing resource than as logs and soybean fields.

� NORTH AMERICA: Jay Schadler will report from an astonishing solar power plant in Arizona on how alternative power solutions will help the energy grid.

� AUSTRALIA: Bill Weir will be at the barrier reef off the Australian coast to report on how desalination plants may be an answer to water shortages.

Additionally, "Planet Earth 2007: Seven Ways to Help Save the World" will focus on how we all can make a difference. "Many Americans are saying they want to do what they can to slow the damaging effects of global warming, and this broadcast will offer concrete solutions that could be achieved on a global level, as well as a smaller level inside our viewers' own homes," said co-executive producer John Green.
