Smith said humans are moving into areas where once animals were predominate.
"We really look to explore a lot of this overlap," Smith said at a Nat Geo press conference last month. "Most of it probably occurs as a result of what we do, but there are a few occasions when the animals do come in. But, really, it's to really understand how these animals are so adaptive, take advantage of a new habitat, essentially, and oftentimes live right under our noses without us even knowing about it."
Smith said while it makes the news when animals and humans clash, "Urban Jungle" also shows animals' peaceful adaptation.
"There are populations that really have learned how to exist there," he said. "They really don't want anything to do with us, but they have learned to take advantage of us. That's what we really want to do is ultimately educate people that, 'Hey, look. There is some really cool stuff happening.' We see it in the wild often, but sometimes it's different. And if we can educate people and make them understand, I think we will be doing a good job."
And sometimes wildlife helps in urban areas, according to Nat Geo Wild general manager Geoff Luck.
"We filmed coyotes in Chicago. There are more than 2,000 coyotes that live within the city limits full‑time, and when they are needing to be removed or taken out of a particular area, the authorities let them go again because they help control the rodent population," Luck said. "They are still eating their wild prey. They are not eating garbage."
