Answer:
The elements used in the documentary support a positive change in relation to the changes caused by time.
Step-by-step explanation:
"Rivers and Tides" is a documentary that seeks to stimulate the public's reflection on the beauty and treasures that nature can offer, not only in relation to plants and animals, but also in relation to stones, water, ice, soil and all the elements that make up the world we live in. The docuemtario presents these elements in an ephemeral and transcendental way, allowing us to understand how beautiful and strong they are and how finite, liable to degradation with time, but degradation, death, is portrayed as something positive, which allows the maintenance of all this beauty and that promotes an end, but also promotes a new beginning.
