Top water wasters

Interesting piece in Scientific American on how we waste water. Everything from the washing of dishes and cars to the production of biofuels is outlined here as some of the top water wasters.

But this is my favourite one:

10. Wasting Water by Getting “Wasted”
As refreshing and cooling as that beer may taste, it’s likely to leave you less hydrated than you were before you started. Alcohol is a diuretic, which means it increases the frequency of urination (but you knew that already). Alcohol suppresses an antidiuretic hormone called vasopressin that tells our kidneys to reabsorb and conserve water. The more you drink, the more the hormone level falls, and thus the more water you lose. Severe dehydration is a big reason why after a hard night out, you end up with a hangover the next day.
