      Liberals are really more likely to drink lattes than conservatives, but not for the reason the cliché suggests. https://www.cambridge.org/core/journals/ps-political-science-and-politics/article/real-reason-liberals-drink-lattes/5544153706BEFC44374ECB6BDF5169A8 …pic.twitter.com/R2XPlNkXG0

      By the way: Coffee drinkers should be aware that their habit is one of the worst environmental sins. https://www.degruyter.com/view/j/lehr.2017.11.issue-2/lehr-2017-0008/lehr-2017-0008.xml …pic.twitter.com/TtwiuOb0hG

          Don't get too shaken up by coffee's water use. The average American consumes 7800 L/day in virtual water, of which 1700 L/day through meat, and another 700 L/day in milk. To get to an average meat level of virtual water use through coffee, you're up at 13 cups/day.

          Here's the reference for US virtual water use, it's by the same guys who did the coffee analysis.http://www.pnas.org/content/109/9/3232 …

          Kind of assumes that all water use is equally bad. I know NO ONE in NE Italy / W. Slovenia / NW Croatia who irrigates their olive trees and irrigated potatoes are almost unknown in Europe (as are irrigated wheat / barley). Olives / potatoes / winter cereals are rainfed.

          Except that, on a daily basis, people consume 10 g of coffee grounds at most, but certainly more than 200 g of meat. The way the information is put in this except is heavily biased.

          "At most" enough for 1.45 cups? Yeah, no. Especially if we're talking not national averages, but consider only those who drink more than 0 cups. Worry about water is dumb inherently, though. That's what prices are for.

          surely the water does not depart our planet should we not be examining how much of this water is contaminated or spoiled in some way rather than measuring it in cups?

          Correct, in theory water can be reused much more efficiently than other resources, but wouldnt take this for granted

          For whatever it's worth- Spent coffee grounds make great compost for soil enhancement. Works in every type of composting. Not nearly as true for many other kitchen scraps.

          my unscientific observation is that a lot of coffee comes from rainy places like South America and Indonesia
