Our almond habit is sucking California dry:

Fascinating Mother Jones story.

Seriously? Farmers are spending a million dollars to drill each well to 2500', in order to get enough water to grow almonds? This is drawing down the aquifers faster than they can replenish themselves. The San Joaquin Valley is dropping 11 inches per year.

A similar story is in West Texas, where the industrial-sized cotton farms are so thirsty that the aquifer there is going dry.

That is not sustainable. That is treating the Earth like it is a throwaway resource. Until our space travel capability gets much more advanced, this is nuts, pardon the pun.
