When National Geographic approached with an opportunity to swim with sharks to kick off its it was an easy yes for the Marvel star who is the new Captain America.

The water, says Mackie, is a 91裸聊视频渟afe space91裸聊视频� where he 91裸聊视频渃an just tune everybody and everything else out.91裸聊视频�

Mackie has been a certified scuba diver for nearly two decades. 91裸聊视频淚91裸聊视频檝e swam with some crazy stuff, and I91裸聊视频檝e swam with sharks before. I just swam with Great Whites in South Africa. I did whale sharks in Mexico. I swam with a blue whale off the coast of Cape Town.91裸聊视频�

For debuting Thursday, he wanted cameras to visit the waters near where he is a regular boater and fisherman. An increase of sharks in the area are swarming boats and eating fishermen91裸聊视频檚 catches, leading to a greater risk of hungry sharks becoming aggressive. This points to a larger environmental issue that the ecosystem is off-kilter.

91裸聊视频淚f we eat all the fish, the sharks have nothing to eat,91裸聊视频� said Mackie. 91裸聊视频淪harks have babies in Lake Pontchartrain and Lake Catherine. When their babies come out, they91裸聊视频檙e full-grown pups. They91裸聊视频檙e three-foot sharks91裸聊视频� They91裸聊视频檙e not predators, but they also need a substantial food source.91裸聊视频�

Mackie says he was in the water for about four hours and 91裸聊视频渋t91裸聊视频檚 not that hard to find a multitude of sharks in the Atlantic Ocean.91裸聊视频� Seeing the sharks up-close reminded him 91裸聊视频渉ow majestic and powerful they are, but also you just see how beautiful they are.91裸聊视频� He was accompanied by marine biologist Jasmine Graham, whom Mackie says was his 91裸聊视频渟ecurity blanket91裸聊视频� if it got too intense.

91裸聊视频淓very time it would get to be too much, I would grab her. I91裸聊视频檓 like, 91裸聊视频楾hey91裸聊视频檝e got to pick one. So if one of us getting eaten, it better be you,91裸聊视频�91裸聊视频� he laughed. 91裸聊视频淪he really looked out for me and gave me a lot of information that really opened my eyes to the community that we91裸聊视频檙e in and explaining the sharks91裸聊视频� behavior.91裸聊视频�

Mackie, whose show will be followed soon by Discovery91裸聊视频檚 Shark Week programing, also hopes to highlight the effects of global climate change on the coastline of New Orleans where . Global warming has both caused snow and ice to melt and it91裸聊视频檚 led to more storms that cause flooding. Also, activity from the oil and gas industry weakens the soil.

91裸聊视频淭he area around New Orleans is slowly going away. You know, the water is starting to eat away at our habitat, our home,91裸聊视频� said Mackie. 91裸聊视频淭here are certain areas where I used to go as a kid, and those areas are gone now, like oyster farms,91裸聊视频� said Mackie.

91裸聊视频淲e used to go fishing when I was little and my uncle would put me in the water. I would walk around and field for oysters with my feet, put them in a boat, and we would eat those oysters for lunch. Whole oyster beds are gone.91裸聊视频�

For someone whose career has afforded him the opportunity to travel the globe both for work and pleasure, Mackie says there truly is no place like New Orleans.

91裸聊视频淭here91裸聊视频檚 nothing more beautiful than seeing the sun come up over the Gulf of Mexico. It91裸聊视频檚 literally breathtaking and I91裸聊视频檝e seen the sun come up over everything. When you91裸聊视频檙e in a boat, going out to the Gulf or even Lake Catherine and you see the sun come up over that marsh and wetland, there91裸聊视频檚 nothing like it.91裸聊视频�
