I agree but then using a volume of water as a measure without provided context is just fearmongering. Draining oasis in a desert might have much higher impact than one of the thousands of lakes in canada but still, it's a renewable resource. Most of the places suitable for datacenters have plenty of it anyway as datacenters are more suited for colder climates which usually have plenty of water.
