Zambia's population to triple by 2050

The United Nations has announced that the world's population has reached seven billion.

The number of people on the planet is now rising by around 80 million a year.

In Zambia, the UN predicts that the population could triple by 2050, reaching 100 million by the end of the century.

BBC Health Correspondent, Fergus Walsh, went to a village just outside Lusaka to visit Catherine Phiri, who had just had a baby girl.

He also spoke to Duah Owusu-Sarfo, from the United Nations Population Fund, and Annie Sampa, from Unicef.
