We're worse with food waste than we think - BBC
Common estimates for global food waste are too low, according to Dutch researchers, who suggest every person in the world is wasting about 500 calories of food a day.
Without waste, we could feed five people instead of four, they said.
The study found food waste goes up with the increase of money in our pockets, possibly reaching more than twice the levels we thought previously.
Reducing food waste is a key challenge in fighting climate change.
Wasted and lost food accounts for almost 10% of all our greenhouse gas emissions, according to the UN.
