Millions of lives are on the line as leaders meet at the World Food Summit in Rome next week. The world produces enough food to feed everyone. Yet the number of people suffering from chronic hunger across the planet has reached the record−high figure of 1 billion this year. This is a scandal.

The best solution is funding to boost sustainable agriculture in poorer countries, but France, Germany, UK, Italy and Japan are backing out on a $20 billion promise made earlier this year.

We have teamed up with Avaaz and global farmers' networks to show our governments that we refuse to accept a world where people die every minute from hunger.
