Freshwater ecosystems are really feeling the heat from climate change, and that’s a big problem! Here’s how rising temperatures and changes in rainfall are affecting them:
Warmer Waters: When temperatures go up, it can cause thermal pollution. This means it gets too warm for some fish to live. Cold-water fish like trout may have a hard time surviving, while fish that like warm water can do better.
Changing Rainfall: When it rains more or less than usual, it can cause floods or droughts. Floods can wash away homes for fish and plants, while droughts can lower the water levels. This affects where fish lay their eggs and how plants grow.
Extra Nutrients: Heavy rains can wash lots of nutrients into lakes and rivers. While nutrients are normally good, too much can lead to dangerous algal blooms. This can use up the oxygen in the water and harm fish and other creatures.
Losing Habitats: Changes in how water flows can wear away shorelines. This can break the balance of these natural habitats, making it harder for plants and animals to thrive.
Overall, the effects of warmer temperatures and changing rainfall patterns can upset freshwater ecosystems. This threatens the variety of life in these environments and the quality of our water. It's a chain reaction that we really need to pay attention to!
