ALEX CHADWICK, host: Explorer and conservationist Mike Fay spent months flying over the      continent of Africa in a small plane at a low altitude, gathering data,      photographing everything he saw, trying to answer some big questions.</s>Mr. MIKE FAY (Photographer): What's happening down there?  Is there any      wildlife?  Are the trees still there?  Is the vegetation, you know, OK,      or the soil's eroding?  And how rich are people on the ground?  What are      they living like?</s>ALEX CHADWICK, host: His survey was called the Africa MegaFlyover, funded by the      Wildlife Conservation Society and the National Geographic Society.  Mike      Fay's goal was to document the relationships between Africans and their      ecosystems--in other words, the human landscape and how it affects the      environment.  Tomorrow on the program, we'll hear from Mike Fay about      what he saw.</s>Mr. MIKE FAY (Photographer): We started in South Africa, flew up all through Namibia,      Botswana, Zambia, Mozambique, Madagascar, Tanzania, Kenya, Uganda,      Democratic Republic of Congo, Central African Republic, all the way      through the Sahel, up along the Atlantic coast and ended up in Portugal,      70,000 miles later.</s>ALEX CHADWICK, host: You've worked in Africa for 30 years, but still you must have      been seeing places that you haven't seen before.</s>Mr. MIKE FAY (Photographer): Oh, man.  I mean, just dreaming about those places for decades,      the skeleton coast of Namibia, the archipelagos along the coast of the      Indian Ocean, the islands around Madagascar, the dunes of the Sahara      Desert.  All those places I'd never seen, so it was like a dream come      true for me.</s>ALEX CHADWICK, host: Mike Fay, the Radio Expedition's interview tomorrow on DAY TO      DAY.</s>ALEX CHADWICK, host: I'm Alex Chadwick.  NPR's DAY TO DAY continues.
On Wednesday, Day to Day will feature a conversation between Alex Chadwick and Mike Fay, who flew 70,000 miles over Africa in a small plane to make a photographic survey of much of the continent. His goal was to survey the relationship between Africans and their environment. The survey was funded by the Wildlife Conservation Society and the National Geographic Society.
