Let's go back to ginger. Good morning again, ginger. Good morning to you, robin. I know you've seen the glory of these waterfalls but it really was glorious for us to meet the people who survive on this water. And see a lot of the animals that use this as an artery to their life. Are the rushing water plummeting 34 stories. The sound and mist heard and seen for miles. And we're heading to an island right in the middle of it all. So speedboat is going to be how we get to the edge of the falls. This is the river that is on the Zambia side and the river and the falls separate countries. We're going to go to livingstone island where we can see Zimbabwe. Here we go. This is where we get off. This is livingstone island. You've done this forever, right? How many have you lost? Zero. Zero. Good morning, America. Here we are in angels pool on the edge of Victoria falls. That's a 354-foot drop. I don't plan to go over. Daredevils swimming on the edge. Doing it for the gram. To get a great pick our. How was it? I had to close my eyes. But this story is not just about these majestic falls but about the zambezi river that fills it. Wildlife is struggling. This waterfall is a way of purifying the source and sustaining the lives of those who live along its banks. Reporter: All through our journey, reminders that the land belongs to the animals and if the animals are feeling it, the people are too. What does this village like? The guide gives us a tour and a reality check. It's problems like hunger, you know. You've seen the hunger. We saw it, yes. Reporter: And this village relies on tourism. What are these guys doing? Making animals. This is our main source of income. Reporter: The falls are a huge part of the economy here. Tourists pour millions into the region so when reports suggested Victoria falls might be drying up it was alarming. Here we are Reporter: We need to listen to the message they are telling us.

You told me something interesting about Africa. That's right. Right now the U.S. And China are the largest emitters. But we have to remember that the historic record for carbon emissions is held by the U.S. Throughout history we have put more carbon into the atmosphere than any other country. And you have to realize that we're 4% of the population and we're responsible for somewhere between a quarter to a third of all global emissions. If you compare that to where we are right now, 54 African nations making up this vast continent have contributed a mere 4%. That's a stark contrast and it's especially poignant when you realize this is the continent, Africa, that's most at risk for many of the negative effects of climate change. And carbon emissions being related to climate change. That's what is warming our planet. Stunning information. It really is. On a personal level, what are each of you going to take away from being in such a special place? I'll let Nichole start. Right. I mean, standing here in front of this amazing awesome power of the falls it's so clear to me the intimate ties between ourself and the natural world, between Africa and the rest of the world and makes me think about our responsibility and the choices we're making. Climate change doesn't have borders. You know, if we're going to move forward and we're going to department to the challenges to come and already under way through climate change we have to do it together and make thee think about the responsibility I have and what we can do collectively to help take care of our planet. That was the best answer but I'll try to follow that up. I would say the interconnectedness of us is fascinating but also it's really about to me I edge on fear sometimes but this has made me hopeful that there are people doing the right thing. There are parts of Africa you were telling me where plastic bags have been banned and you even get fined so I feel like there are things we can do to clean this planet up and I know people are doing them. We just have to start. We can do a lot better. And we need to. We're feeling it, robin. It's gorgeous and it's so powerful to have you there and I got to say I follow nat geoon Instagram, the pictures, the story, absolutely beautiful and really bringing us all together so safe travels back home, both of you and thank you for being there for us.
