Vegetarian food can save hunger and the world food crisis. Meat is one of the main causes of the world food crisis. Based on an ecologist at Cornell University in the United States, David Pimentel stated that livestock-cows, chickens, pigs, ducks eat five times more grains than the American population. We could relate it to Malaysia's perspective, if we could just cut down half of the consumption of meat, there will be enough food to feed the citizens and no hungry people in the world. The decrease in meat consumption, the decrease in using more grains to feed livestock animals. Jean Mayer, the nutritionist from Harvard University stated that we could save enough grains for 60 million people by cutting down 10% of meat consumption.

Having a meatless diet can save more animals in our world. The way a vegetarian saves animals is by reducing the demand for meat and causing fewer animals to be born into a harsh life owned by the meat industry, where callousness abounds and mercy is scant. It also enables more people to have a taste of vegetarian food and get to know more knowledge about vegetarianism. A vegetarian diet is one of the healthy diets that is becoming a trend in the future. Most of the nutrients can be obtained through vegetarian food. Besides, vegetarianism is also very good for environmental protection.
