Former Vice President Al Gore wants people to have fewer children to save the planet.
During an interview at the Games for Change Festival held in New York City on Monday, he connected the global population to pollution.
"One of the things we could do about it is to change the technologies, to put out less of this pollution, to stabilize the population, and one of the principle ways of doing that is to empower and educate girls and women. You have to have ubiquitous availability of fertility management so women can choose how many children have, the spacing of the children," Gore said.
"You have to lift child survival rates so that parents feel comfortable having small families and most important - you have to educate girls and empower women. And that's the most powerful leveraging factor, and when that happens, then the population begins to stabilize and societies begin to make better choices and more balanced choices," he reasoned.
Gore believes carbon dioxide emissions from human activities are the cause of global warming. He cites the wildfires in Arizona and the flooding along the Mississippi River, saying humans need to take action to stop these kinds of disasters.
Gore and his wife Tipper have four children.
