Is killing animals for food ever morally justifiable? If the entire planet could survive eating only a vegetarian diet, how could we be justified in killing millions of animals a year? Wireless Philosophy tackles these questions in this video.

An astounding one in eight people on the planet are undernourished, over three million children die every year from hunger or malnutrition, and two billion people suffer from one or more micronutrient deficiencies (Caritas). And as the world’s population continues to grow, with estimates putting it at ten billion by 2050, we can only expect the situation to get worse. Unless, of course, we do something about it.
