Freshwater environments are ecosystems that contain water with low salt concentration, typically found in rivers, lakes, ponds, and wetlands. These habitats support a diverse range of plant and animal life, including species like fish, frogs, and water lilies. Freshwater ecosystems play a crucial role in the Earth's water cycle and provide essential resources for human activities. These environments are vital for drinking water, agriculture, and recreation. They also help filter pollutants and provide habitats for wildlife. Protecting freshwater ecosystems is important for maintaining biodiversity and ensuring the health of the planet's water resources.
