First off, that is a huge problem as it leads to saltwater innundation of major rivers in breadbasket regions. But there are many other effects to expect. Wet bulb too high, temperatures too high for crops to survive (only needs to be a few days a year), droughts that destroy crops, floods that destroy crops and wash away top soil, reduction in glaciers drying up rivers that provide water to ... crops. If you salt the earth where the majority of food for a species grows. Then you can expect a large reduction in the population of that species.
