Food is one issue that cannot be solved person by person. We have to stand together.

This isn't one of those rare diseases that we don't have the solution for. We know how to fix hunger.

Eighty percent of the people in the world have no food safety net. When disaster strikes — the economy gets blown, people lose a job, floods, war, conflict, bad governance, all of those things — there is nothing to fall back on.

One cup of food a day changes Fabian's life completely. But this morning, about a billion people on Earth - or one out of every seven - woke up and didn't even know how to fill this cup. One out of every seven people.

If any good comes out of the current famine in the Horn of Africa - amidst the pictures of mothers carrying dying babies at their shrivelled breasts and hollow-eyed children with swollen bellies and matchstick limbs - it will be galvanising the world on the need to ensure access to nutritious food for the world's most vulnerable people.

Every 10 seconds we lose a child to hunger. This is more than HIV/AIDS, malaria and tuberculosis combined.

Seize the moment – don’t wait for anyone to give you permission.
