My view: To feed the world, look to veterinarians

In many countries, the cause isn't a lack of food — it's a lack of safe food. The risk of malnutrition caused by unsafe food is increasing, as human populations grow and continue to urbanize. This public health problem can be solved — not by doctors but by veterinarians. They're crucial to safeguarding the health of animals that are the foundation of the world's food supply. Unfortunately, well-trained veterinarians are in short supply worldwide. To improve global food safety, that has to change. The world's population will increase by 2.6 billion by 2050. Feeding these billions of new mouths will require a 70 percent boost in food production — including 200 million tons of meat. Increasing levels of urbanization will make it harder to meet the demand for animal protein. Seven in 10 people will live in cities by 2050. Even a minor disruption in the food supply for one densely populated megacity could lead to a humanitarian catastrophe.
