Ambassador Gillian Bird spoke to students at the Icahn Charter School about her role with the United Nations.

It’s all part of the NYC Junior Ambassadors program. It's operated by the Mayor’s Office for International Affairs.

The program gives 7th graders across the city a chance to learn about the U.N. in hopes of inspiring young people to find solutions to global issues.

These kids focused on children’s rights and advocated against gun violence.

They organized a school walkout and wrote a letter to President Trump.

"It's really a rewarding opportunity to share what I am trying to achieve as an ambassador and to engage young people," said Gillian Bird, Ambassador of Australia to the United Nations.

Officials say there are more than 500 students participating in the program. 

Each school receives a visit from an ambassador once a year.

The students will also tour the U.N.
