My thinking is that if you dump brine into the sea you're a putting in a liquid that marine life can swim though and be harmed by. Another problem is just how to get the byproducts of desalination away from the plant. If the salt were made into a boat, it could be sailed away (moved more easily than on land) and could mix with seawater over a much wider area. Even if it sinks after a short period, it would still be in a rock-like form that would mix with seawater over a longer time period. Similar to how the salt in the sea came from rocks originally?
