Pretty eye-opening Google Earth footage here and some common-sense analysis by environmental sociologist Anthony Silvaggio, who narrates this flyover of the impact from industrial scale pot growers. Bottom line: Because marijuana prohibition has created a situation where present-day laws are all over the map, there is no legitimate industry regulation.

According to some estimates, the 3-6 gallons of water necessary to grow each plant–when multiplied by thousands of plants in industrial scale operations–may account for 20% to 30% of the net flows of local waterways in low-water years.

As with everything else, do you know where your ‘produce’ comes from?
