What too much salt does to our freshwater

Agriculture, mining and climate change are three factors driving up the salinity levels in our freshwater ecosystems.

Higher concentrations of salt in places like rivers, can drastically change these ecosystems where vertebrates and invertebrates alike, struggle to adapt to new conditions.

Renee Dowse has been studying freshwater ecology for more than 15 years and says although we’ve observed how higher salinity levels can create problems, we still don’t know what all those problems are.
