Part 4/8:
Mangroves play a crucial role in this delta ecosystem. They not only thrive in the saline environment but also serve as a protective barrier against the erosive forces of the river. These mangrove root systems provide shelter for creatures such as manatees, also known as sea cows, which are increasingly threatened by boat traffic. The filmmakers witness the delicate balance of life in this sanctuary, where species like the scarlet ibis and various fish flourish.
