The main point they are trying to make is the people eating most of the beef are dying off. If the trend holds and younger generations don't drastically increase beef consumption, there just won't be anyone to eat the same amount of beef they are producing currently. Therefore, they will have to reduce beef production which may reduce water used when growing food to feed the cattle as fewer cattle eat less food. So they are pointing out this problem may resolve itself somewhat as the people that industry relies on die out or retire to an income less able to buy steak for every meal.
