Antweiler added that there is a lot that California can and should do to manage their water sources, including the use of water in agriculture.
One suggestion I would make to California and BC is to limit animal agriculture water use as 1kg of beef uses 15,415 litres of water to produce.
California should shift to plant-based agriculture, install bidets to reduce water needed to grow trees, install water leak detectors along water pipelines, grow produce intended for the climate and implement more rain water collection systems as there are many efficiencies that could be made without resorting the need of water from other jurisdictions
