Tackling fatness may be 'critical to world food security'

Increasing biomass will have important implications for global resource requirements, including food demand and the overall ecological footprint of our species. Although the concept of biomass is rarely applied to the human species, the ecological implications of increasing body mass are significant and ought to be taken into account when evaluating future trends and planning for future resource challenges. Tackling population fatness may be critical to world food security and ecological sustainability.

Everyone accepts that population growth threatens global environmental sustainability - our study shows that population fatness is also a major threat. Unless we tackle both population and fatness, our chances are slim.
