Before she became a world-famous primatologist and peace ambassador, a young Jane Goodall almost didn't find the money to keep studying chimpanzees.

But fortunately, just before that time came, I saw the first observations of using and making tools, and that was the saving

observation, the breakthrough. It's Tuesday, December 31st. It's the last day of 2024, and this

is Science Friday. I'm John Dankowski, a very happy New Year's Eve to you, however you're celebrating.

We're also celebrating our 33rd anniversary, and earlier this year we asked you to vote on some of your favorite sci-fry segments from the past three decades.

And many of you wanted to hear from primatologist and researcher Jane Goodall once again.

She's been on the show a number of times over the years,

but we wanted to feature this conversation from 2002.

She had just been named a UN messenger of peace,

and she was also part of a documentary called Jane Goodall's Wild Chimpanzees.

She just finished a book called The Ten Trusts,

What We Must Do for the Animals We Love.

Dr. Jane Goodall joined Ira Flato in our New York studios. Let's listen back.

Thank you very much for coming in to join us today.

Thanks for inviting me.

What is a United Nations messenger of peace?

You're very proud of that, I know.

Well, I feel it's a great responsibility.

There are nine of us pointed by Kofi and I'm the Secretary General himself.

And I think he appointed me because I was explaining to him about our youth program, Roots and Shoots,

which is involving young people in 60 countries in hands-on projects to make this world a better place

for animals, people and the environment that we share. And it's very much about breaking down barriers
