It will likely have some (small) impact just due to the scale of its use. However, the process is not too different from sea salt production... You're evaporating a brine, usually. And you're displacing fossil fuel use with a material that can be recycled, so instead of constantly mining for fossil fuels, we can just extract the material once.

Additionally, it can be extracted from seawater at a price that isn't insane, most affordably through desalination discharge brine. So in that sense, it could actually improve water usage by helping offset the cost of desalination.

So a huge net positive compared to our current system and with a pathway to eliminate the negative impact entirely.
