Oops, RnD team accidentally created indestructible Salmonella bacteria which consumes flesh. Management was pushing RnD to create a better bacteria because hobbyist grill people were killing the bacteria and bypassing the DRM on the grill, but it escaped the lab. It has infected nearly all animals other than sea fish because of proximity. Survivors build floating cities on the sea and thus we have Waterworld!
