The number of girls married in Africa is expected to double in the next 35 years, experts say. That means almost half, or 310 million girls, by 2050 will be married before they reach adulthood says a United Nation's report. The African Union says it wants to end child marriage in Africa.
Delegates at a summit in Zambia are expected to set 18 years old as the lowest legal age for marriage across the continent. Marriage before age 18 is already against the law in African countries.
Yet the UN says more than 125 million African women and girls alive today were married before their 18th birthday. Experts say that most were given to men in traditional or religious unions in violation of the law.
African Union chairwoman Nkosozana Dlamini Zuma says local culture that undervalues girls and women is to blame. Poverty and lack of education are also responsible, experts say.

Waste products from a popular alcoholic drink could be used in the future to make biofuel. Researchers say the new fuel, based on whisky, could reduce demand for oil. They say using less oil could cut pollution that studies have linked to climate change.
Scotland is the largest producer of whisky in the world. And a Scottish professor has found how to take the waste products from distilling whiskey and turn them into a form of alcohol called biobutanol. Biobutanol can be used as a fuel. Whisky comes from grain, such as corn and wheat.
Martin Tangney is director of what comes out can be considered whisky. The rest is mainly one of two unwanted products: Strong beer and wheat. Tangney says the two byproducts can be produced to create a new material: biobutanol.

For several years, human resources director Pete Tapaskar says it's been a challenge to fill all the jobs at his suburban Chicago-based technology company. Getting high skilled people is still a challenge.
Elizabeth Sue is principal policy analyst for the Chicago Metropolitan Agency for Planning, who studies Chicago's recent immigration trends. She said " They are slowly moving into the south, especially Texas, and Atlanta, Georgia. What we are seeing right now is a substantially decreased total of international in-migrations. Prior to the recession we were between 50 and 60 thousand most years. Now since 2010, we've been at about 23-to24- thousand international in-migrations on a net basis. She says that dramatic drop- as much as two- third some years --contributes to Chicago's overall still population growth.
Tapaska says there are many reasons why immigrants choose to live in Southern states instead of Chicago. "The environment there is ideal for starting a business, could be the taxes there are low, and employers are getting a lot of benefits from the state government."
But Tapaskar says one thing that could bring new immigrants to Chicago is increasing the number of work visas that would attract the highly skilled tech workers his business needs.
