I'm just full of cheery news today. This is rather alarming.

Osteoporosis in water fleas? Give us a break. (There must be some good news out there.)
But it does sound terrible; and it makes one wonder what else is happening that we haven't yet noticed.
What about extremophiles? They could evolve to replace the fleas. I've every confidence that life won't be extinguished.
I'm surprised acid rain is still a problem - I'm woefully ignorant of pollution issues, but I thought regulation and pollution controls have abated the problems quite a bit.

I am proud to state that I live in the province that is the number one acid-rain producer in Canada.
I've forgotten more about acid rain than I still remember, but I wouldn't think it has gone away. There are still signs of acid rain damage to plants in the UK.
In the UK there is less electricity produced by Coal fired Power Stations, and we don't burn coal in domestic fires, and I think the Scandinavians have stopped blaming us for their acid lakes, however globally there probably has still been an increase because the population has increased, and clean technologies have not been given freely to expanding third world economies. China had to almost turn everything off during the Olympics to prevent a bad public relations disaster. To join the EU, Poland has been asked to reduce it's pollution, but it's power production relies almost exclusively on Coal. There are impossible things being asked of them. There has also been a world wide shift from the low sulphur hard coals (anthracite) we have in the UK to higher sulphur coals and dirty shales.
And Acid Rain does not only come from SO2. Cars may be much cleaner today, but there are a lot more of them, and in many places NO2 is the main problem.
In the UK, we don't have the pea-souper smogs of the 1950's anymore, but there are many cities around the world that still have severe pollution problems, especially with low level ozone and NO2.
