Rice is… really really no where near the top of the chain on problematic crops. It’s mostly grown for direct human consumption, unlike corn and soy, and, although quite water intensive (at least for wetland rice cultivation) most of the production is done in areas with the water resources to support it, Yangtze river, peal river, Mekong delta, Ganges river, the lower Mississippi river, ect ect.

Obviously there are some serious issues with conventional rice cultivation, but, in terms of the number of people it supports relative to the over all impact it has… it’s definitely not something the average consumer should be putting at the top of their list to cut out.
