2050: The world will compete for food

World population may rise to 9 billion people by 2050, pushing countries into a struggle for food because of limited supply, US scientists have warned.

The Association for the Advancement of American Science said that the world population will increase rapidly in poor countries, meaning that food production in the next 40 years must increase by the amount produced in the last 8,000 years. .

The population in Africa and South Asia is expected to increase the most, and the incomes of those countries are expected to increase four times during this period. This will make food supply tense because studies show that people with higher incomes often consume more food.

' In the last 20 years, very little money has been invested in family planning. If you invest in this work right now, it will both curb population growth, improve your life and solve many environmental problems , 'said John Bongaart, working at Lien's population agency. country, say.

World population is expected to increase to 10 billion by 2100. Life expectancy in developed countries may exceed 100 by the end of this century.
