How are freshwater animals adapted to their environment?

Freshwater animals adapt to their environment through gills that obtain oxygen and allow them to live in rivers and streams in which the water is cooler and has a higher oxygen level. Freshwater animals also need to swim fast to catch food and utilize their environment to create their home.

Why are freshwater animals going extinct?

Freshwater animals are going extinct due to the creation of man-made elements that block migration routes for fish and disrupt habitats. The water withdrawal for human use also shrinks and degrades habitats as well as the draining of wetlands for development depletes habitats. Other reasons include overexploitation, pollution, and global warming.

How can we protect freshwater fish?

We can protect freshwater fish by establishing multiple solutions. These solutions include restricting the construction of dams and establishing protected wetlands. Other solutions to protect freshwater fish are regulating water withdrawal for human use and incentive for farming businesses to reduce the use of pesticides.
