<human>:  When did the Third World food crisis start?
<bot>: The Third World food crisis began in the 1970s and 1980s. It was caused by a combination of several factors, including the population explosion, the rise of globalization, and the development of modern agriculture. The population explosion led to a massive increase in the demand for food, and the modern agricultural industry was not able to keep up with the increased demand. As a result, the price of food rose, and people began to starve.
