Not entirely accurate:
> The virtual water trade (also known as embedded or embodied water) is the hidden flow of water in food or other commodities that are traded from one place to another.[1] The virtual water trade is the idea that when goods and services are exchanged, so is virtual water.

A concrete example from another comment:
> With the Saudi Arabian landscape there being mostly desert and alfalfa being a water-intensive crop, growing it there has always been expensive and draining on scarce water resources, to the point that the Saudi government finally outlawed the practice in 2016. In the wake of the ban, Almarai decided to purchase land wherever it is cheap and has favorable water conditions to produce enough feed for its 93,000 cows.

Cloud seeding is being studied.
This makes no sense as a response. Water usage is a local issue where water goes through X rather than Y. Water usage in Pakistan has zero effect on Germany, unlike CO2 emmissions.
If an entire river got diverted to lawns then the effects would only be between the divert point and the sea (in the form of the river nor being available for other people to divert from and animal life not having a river to live in) and even those effects are mostly temporary. Heck, lawn water mostly goes back in to the water table, with the rest evaporating to make clouds to then fall back as rain.
