Ongoing discussion about the potential effects of ocean acidification on deep-sea corals has me wondering about the case of acid rain in North American lakes. This is something we understand much better. Environment Canada has a great looking and informative Freshwater Website that includes this handy graphic here.
Isn’t it amazing that acid rain can have almost the same pH as battery acid? And that freshwater fish can survive in such a large range of conditions? I find it remarkable. Of course, you won’t find “freshwater corals” in any lake, so its just food for thought, a bit like comparing apples to oranges.
