By the end of this century, humans will eat 80% more.

Original title: At the end of this century,
80% more physical energy, but more physical exercise. A new German study published in the American journal Public Library of Science says global food consumption will increase by 80% by the end of the century.
united Nations World Population Outlook report, the global population is expected to increase from nearly 7 billion in 2010 to nearly 11 billion in 2100. A model study by researchers Dr. Lutz Depenbus and Professor Stephen Klassen of the World Vegetable Center at the University of Gottingen in Germany found that population growth is expected to increase human food calorie intake by 60 percent, while the expected increase in the height and weight ratio of the population will lead to an increase in calorie intake of more than 18 percent. Specifically, assuming both body mass index (BMI) and height increase, the amount of energy per person per day will increase by 253 kca (equivalent to two large bananas or a serving of French fries) between 2010 and 2100. At this rate of increase, the total amount of food that the global population "eats more" is equivalent to the total food needs of India and Nigeria in 2010. New research also shows that sub-Saharan African countries will be most affected by future increases in global calorie demand. The key reason is that the region is experiencing a period of rapid population growth, with a sharp increase in the demand for calories. Researchers warn that global food policies could exacerbate the food crisis and economic inequality if they fail to adapt to the growing calorie needs of the population. Malnutrition is likely to increase in some poor areas.
for health, scientists are calling on the public to reduce their food intake appropriately. The latest study, published in the British journal Nature Metabolism, by the Max Planck Institute for Aging Biology in Germany, the University of Cologne in Germany, the Barbraham Institute in the UK and University College London in the UK suggests that the fuller you eat, the sooner you die. The study found that mice entering old age began to reduce their food intake and their overall health improved significantly. But scientists suggest that healthy behaviors are best cultivated early in life so that they can stay healthy and long in old age.
