Toby Ord - Giving What We Can

Which charities give more bang for your buck? Australian Toby Ord says some charities are up to 1000 times more effective than others. Toby is a researcher in moral philosophy at Oxford University and founder of an organisation based there called Giving What We Can, whose members pledge to donate 10 percent of their income to the charities that they believe will most effectively help people living in poverty.
