This week, leaders from around the world poured into New York City for the United Nations General Assembly.

Among them was Jane Goodall, one of the world's most well-known environmentalists.

Goodall is best known for her work with chimpanzees.

In 1960, at just 26, she moved to what is now the Gombe National Park in Tanzania.

She became one of the first scientists ever to study chimps in the wild,

and was the first person to observe them using tools

and discovered they have complex social relationships.

Her observations fundamentally changed our understanding of primates forever.

Goodall went on to found the Jane Goodall Institute,

which continues to study chimps,

and runs conservation and educational programs throughout the world.

Today, at the age of 91, Goodall is not slowing down.

She travels 300 days a year to give talks, meet with world leaders, and push for green causes.

But the planet continues to warm.

Forests continue to be cut down.

The list of endangered species keeps getting longer.

And earlier this week, President Trump called climate change a con job.

Goodall has said we're living in dark times.

And earlier this week, I had a chance to ask her,

does she feel like she's fighting a losing battle?
