I find it curious that after all the pages they dedicate to saying that water is getting browner, they say that the primary cause of brownness is a reduction in the amount of acid rain over the last 40 years but some people suspect that warmer weather may be contributing to it as well. If the primary cause is reduction in acid rain, it seems weird to talk about how people aren't going to be able to wash white shirts in lake water as if it is a bad thing and how expensive water filtration systems are. > This change has been taking place since the 1980s, and until the present day the main cause has been a decrease in acid rain. But now researchers think that climate change is also having an effect.
