An international team of researchers has identified five steps for doubling food output amid concerns that one billion people do not have enough food to eat and continued population growth will further strain supply. The study recommends eliminating waste and reducing meat consumption. Using cropland to grow food for humans rather than livestock would increase the number of calories produced per person, the researchers found. "That doesn't mean we all have to become vegetarians and vegans, but even if you ... eat meat one or two days less a week, you can hugely contribute to the amount of food that's needed," said McGill University geography professor Navin Ramankutty.
