A report from the United Nations said that around 60 million people across the world，with 80% of them in Asia，are drinking polluted water.Some 4，500 children die every day because of polluted water.
   A report showed that environmental problems kill 3 million children under five years old each year，making them one of the key contributors in more than 10 million child deaths worldwise each year.
   Dangerous factors include indoor and outdoor air pollution，water pollution，lack of good hygiene facilities and poor ecological systems，it said.
