The end of the low tide resulted in a "sea" of grass that took over the coast of the city of Manaus.

At first glance, it may seem like just common vegetation, but according to biologist André Menezes, what seems harmless represents a threat to the local ecosystem:

- Snakes and alligators can hide in the grass, posing a danger to those who frequent the area.

- Decomposing grass makes the water contaminated and unsafe for water activities.

- Vegetation reduces the oxygenation of the water, harming fish and other living beings in the river.

According to André, everything is related to the oscillation of the waters. "During the river's flood season, the sediments accumulate many nutrients at the bottom. So, when the drought occurs, the soil becomes fertile and suitable for the growth of vegetation. If no one plants, the grass takes advantage and grows," explained the biologist.

As the river rises, the grass that forms is released from the ground, creating a "green carpet". When it is released from the soil, the vegetation becomes dead, full of microorganisms and bacteria, which can pose risks to human health, in addition to harming fish. It is dense and fibrous vegetation that does not disappear easily. Therefore, government action is needed to remove it", warned the biologist.
