In 1984, Wisconsin scientists divided a lake in half and acidified one side to mimic acid rain; bass stopped reproducing, and the fishery collapsed

An experiment in Wisconsin's Little Rock Lake studied acid rain's long-term effects on freshwater environments. Scientists divided the lake and acidified one half to mimic pollution conditions. The treated side experienced a collapse in its fish population and altered plant life. This pioneering study informed air pollution reduction laws in Wisconsin and the United States. After nearly thirty years, the lake's ecosystem gradually returned to its normal state.
