About 840 million, or one of every 14 people on the earth, don’t have enough to eat, according to the United Nations.
Most live in developing countries in Africa and in the Asia-Pacific region.
India alone has about 202 million people who do not get enough food.
Poverty is the main reason people go hungry, and is also responsible for malnutrition, starvation, and famine in some countries.
Humans depend on just 20 plant species for more than 80 percent of their food.
And half the daily calories consumed worldwide come from just three grains: wheat, rice, and corn.
