The Florida Everglades: beautiful, vast
harsh, remote.

00:13.680 --> 00:21.688 align:left position:52.5%,start line:83% size:37.5%
It is a huge wetland. It flows across most of southern Florida
and then it runs into the ocean.

00:21.788 --> 00:28.361 align:left position:70%,start line:83% size:20%
Some of North America's fiercest predators live
here, including the American alligator

00:28.461 --> 00:33.733 align:left position:77.5%,start line:89% size:12.5%
and the bull shark. They're top predators.

00:33.833 --> 00:36.136 align:left position:77.5%,start line:89% size:12.5%
They eat a lot of different types of prey,

00:36.236 --> 00:39.739 align:left position:87.5%,start line:83% size:2.5%
which means they could have a big
impact on a lot of different types of prey populations,

00:39.839 --> 00:43.643 align:left position:30%,start line:89% size:60%
which then could have cascading effects down to lower levels of the food chain.

00:43.743 --> 00:52.852 align:left position:45%,start line:89% size:45%
Despite its wild nature, the Everglades is an ecosystem in trouble.

00:52.952 --> 00:59.759 align:left position:87.5%,start line:83% size:2.5%
For nearly a century, man drained
the swamp now a large-scale restoration

00:59.859 --> 01:05.265 align:left position:82.5%,start line:83% size:7.5%
project aims to return the wetland to
its former glory.

01:05.365 --> 01:09.869 align:left position:52.5%,start line:83% size:37.5%
More and more fresh water is going to come in, so it's really
important we get the water right and we

01:09.969 --> 01:13.506 align:left position:10%,start line:83% size:80%
know how animals like sharks and
alligators respond so we're managing the

01:13.606 --> 01:16.609 align:left position:17.5%,start line:89% size:72.5%
ecosystem right for them.

01:16.709 --> 01:20.080 align:left position:65%,start line:89% size:25%
That's why we're doing these studies, to get an idea

01:20.180 --> 01:24.417 align:left position:85%,start line:83% size:5%
and make predictions about how this
change will affect the ecosystem.

01:24.517 --> 01:28.517 align:left position:72.5%,start line:83% size:17.5%
So we can protect those animals and make sure
they fill that critical ecological role.
