Increased weight and height will require more food

It will be more difficult to supply food to the Earth’s estimated population of 9 billion by 2050, as an average person will need more food in terms of height and weight gain and demographic transition, according to Norwegian researchers.

Professor Daniel B. Müller and colleagues, in their study – that was published in the Sustainability journal – investigated how the population changed in 186 countries between 1975 and 2014.

“We’ve been studying the effects of two phenomena: one that people are getting higher and heavier, the second is that the population is aging” – Gibran Vita, researcher at the Norwegian Science and Technology University. (MTI)
