"A 'like' or a post won't stop a tank or a bullet, but when people are connected, we have a chance to build a common global community with a shared understanding," Zuckerberg told at a private luncheon with business leaders at the United Nations.
"That's a powerful force."
The U.N. member nations on Friday formally adopted a sweeping set of 17 Sustainable Development Goals, or SDGs, that aim to end poverty and combat inequality and climate change over the next 15 years and call for shared peace and prosperity.
The connectivity campaign calls on governments, businesses and innovators to bring the Internet to the some 4 billion people who now do not have access, organizers said.
Signing on to the connectivity campaign were U2 star Bono, co-founder of One, a group that fights extreme poverty; actress Charlize Theron, founder of Africa Outreach Project; philanthropists Bill and Melinda Gates; British entrepreneur Richard Branson; Huffington Post editor Arianna Huffington; Colombian singer Shakira, actor and activist George Takei and Wikipedia co-founder Jimmy Wales.
The Bill and Melinda Gates Foundation on Saturday launched its own roadmap, which put a top priority on improving the health and education for girls.
Melinda Gates said that the health and education of girls was critical to anti-poverty efforts and that the issue had not been sufficiently emphasized in the UN's previous Millennium Development Goals.
