People in Britain are wasting too much of their food, which could have a big effect on hunger around the globe, says Prime Minister Gordon Brown.
Mr Brown said that houses in the UK threw away over £400 worth of food every year, and that waste was helping to drive up food prices everywhere.
The cost of food has gone up a lot in recent months, meaning poorer countries are struggling to get enough to eat.
Mr Brown also wanted to help people in Africa grow more food themselves.
He was speaking at a big meeting of some of the richest nations in the world, called the G8.
The Prime Minister also pointed out that lots of the food grown in poorer countries was wasted because the way it is stored and transported isn't good enough.
