I know that the beaver is one of the most important animals in the world.
They make wetland ecosystems which develops dams. So herbivores can drink and they will slow the river down so they will stay alive. Carnivores can eat the herbivores and we eat them.
Can you imagine the world without meat?
Beavers are caring for their family. They dive into the water and flap their huge tail (it can be heard under water or above.) So other beavers can hide from predators.
Beavers make homes in rivers they slow it down and they don’t notice. Sensitive creatures can now cross the river because the beaver homes are blocking the water from going fast and it makes a dam.
That’s why I think beavers are the best creature I know of.
