Ewan McGregor films an appeal for Pakistan's children

UNICEF UK Ambassador Ewan urges the UK public to help Pakistan's children whose lives have been devastated by the floods. Pakistan is facing a growing humanitarian crisis as worsening floods are affecting even more people than the Boxing Day Tsunami and Haiti earthquake combined. Millions of children have lost their homes and have no food or clean water. More and more of these children are at risk of contracting deadly waterborne diseases like dysentery, diarrhoea and cholera.
