 something of concern. I think it's also interesting that they're finding actually in the Mekong that saltwater is penetrating into the delta, not because of sea level rise, but actually because they're dredging so much sand out of the Mekong that rivers getting deeper and that actually affects the tidal wave. So the salt is going further inland. So in these areas, it's partly sea level rise, but there are other things going on too. But they're having the same net effect of impacts.
