Last month, Nature
spotlighted three insightful new studies chronicling food-related challenges from a global perspective. One presented worrisome new data
on the global rise in the prevalence of diabetes, high blood pressure and liver disease, all linked to obesity. Another presented a new assessment revealing that half of the greenhouse emissions generated by food systems globally are caused by food waste
. Finally, the third study found that food consumption could add “nearly 1 degree Celsius to warming by 2100,” with most of that attributed to global methane emissions from meat, dairy and rice production.
