Of course, these are only estimates. Reasonable people can quibble about the exact size of the gains from a new round. The development argument for a round is equally compelling. It is a tragedy that while our planet is blessed with sufficient resources to feed its 6 billion people, many are going hungry and many are living in the misery that poverty breeds. The first responsibility lies with governments in these poor countries.
Development requires peace.
It requires good governance and sound economic policies. It requires adequate investment in education and health care. It requires protection of human rights and gender equality. But poverty in all its forms is also the greatest challenge to the international community and we will be judged by our response to our most vulnerable members. Poor countries need to grow their way out of poverty.
