00:00:02,335 --> 00:00:13,580
The Florida Everglades: beautiful, vast 
harsh, remote.

2
00:00:13,680 --> 00:00:21,688
It is a huge wetland. It flows across most of southern Florida 
and then it runs into the ocean.

3
00:00:21,788 --> 00:00:28,361
Some of North America's fiercest predators live 
here, including the American alligator

4
00:00:28,461 --> 00:00:33,733
and the bull shark. They're top predators.

5
00:00:33,833 --> 00:00:36,136
They eat a lot of different types of prey,

6
00:00:36,236 --> 00:00:39,739
which means they could have a big 
impact on a lot of different types of prey populations,

7
00:00:39,839 --> 00:00:43,643
which then could have cascading effects down to lower levels of the food chain.

8
00:00:43,743 --> 00:00:52,852
Despite its wild nature, the Everglades is an ecosystem in trouble.

9
00:00:52,952 --> 00:00:59,759
For nearly a century, man drained 
the swamp now a large-scale restoration

10
00:00:59,859 --> 00:01:05,265
project aims to return the wetland to 
its former glory.

11
00:01:05,365 --> 00:01:09,869
More and more fresh water is going to come in, so it's really 
important we get the water right and we

12
00:01:09,969 --> 00:01:13,506
know how animals like sharks and 
alligators respond so we're managing the

13
00:01:13,606 --> 00:01:16,609
ecosystem right for them.

14
00:01:16,709 --> 00:01:20,080
That's why we're doing these studies, to get an idea

15
00:01:20,180 --> 00:01:24,417
and make predictions about how this 
change will affect the ecosystem.

16
00:01:24,517 --> 00:01:28,517
So we can protect those animals and make sure 
they fill that critical ecological role.
