     There are more than one billion people around the world who smoke. Bill Gates, cofounder and

former CEO of Microsoft, wants them all to quit. So does New York City's mayor Michael Bloomberg.

This week, the Gates Foundation, a charity organization set up by Bill Gates and his wife, Melinda,

teamed up with Bloomberg to donate $500 million over the next five years to antitobacco programs.    

     Bloomberg is no stranger to antitobacco plans. He has been fighting tobaccouse in New York City

for years. In 2002, Bloomberg pushed for a ban on smoking in all New York City restaurants.    

     Bloomberg's Initiative to Reduce Tobacco Use was created in 2005.  It aims to discourage smoking

trends around the world by working to change tobacco's image, protect nonsmokers from secondhand

smoke, and help people quit. Bloomberg gave $ 125 million to start the program. Now, he is adding

another $ 250 million. The Gates Foundation will invest $ 125 million over five years to fight the tobacco

epidemic, including a $ 24 million gift directly to the Bloomberg Initiative.    

     The money donated by the Gates Foundation will support antismoking efforts in developing countries

where tobacco use is the highest. "Tobaccocaused diseases have become one of the greatest health

challenges facing developing countries," Gates says. In addition to donating to the Bloomberg Initiative,

the Gates Foundation will also help prevent the tobacco epidemic from taking root in Africa. "The

epidemic in Africa is not well advanced," Gates explains. "That means that we can catch it at an early

stage."

     Tobaccouse kills more than five million people every year. If the trend doesn't change, more than one

billion people could die of tobaccorelated illnesses this century. Gates and Bloomberg have high hopes to

change these statistics. "Together we can make a clear, measurable difference, not just for ourselves and

our generation, but for the generations that come after us," says Bloomberg.
