If a child in its first thousand days - from conception to two years old - does not have adequate nutrition, the damage is irreversible.

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.

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

If a child in its first thousand days - from conception to two years old - does not have adequate nutrition, the damage is irreversible.

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

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.

There’s nothing more haunting than the cry of a child that cannot be returned with food — the most fundamental expectation of every human being.
