exit exams, bottled water, and Biosphere 2

Ok, it's time for some California High School Exit Exam outrage. Sue to get out of high school! Apparently, you can still fail the state exit exam despite meeting local requirements for graduation. I looked at sample math questions, and for once, some of them are practical and useful. So not that anyone asked me, but if you can't pass that, study harder.

Onward to bottled water. We are pretty sure PET bottles don't cause cancer, but we do know that the chemically sensitive community gets in bad trouble with the plasticizers, and it appears that the whole world gets in trouble with the recycling problem, not to mention the artificial drought problem.

And last but not least, Biosphere 2 is not up to code if you want to use it for housing.
