Something else.

My guest today, Lizzie Carr, is on a mission to clean up world's rivers and waterways.

Her organisation, Planet Patrol, is working to eliminate single-use materials and litter,

Lizzie took on her biggest challenge yet, paddleboarding the entire length of the Hudson River in America.

Lizzie, you need to paddle now very hard for 10 minutes.

It was about three miles away from me and it looked humongous.

Lizzie did it all to inspire people to start talking about the plastic polluting our waters.

I'm Ian Wright, and from something else, this is everyday people.

She is working in

the city, earning decent money, but something was missing. Do you know, I was happy, but I wasn't

fulfilled. Right. I think at the time I thought I was happy. I thought I was achieving what I wanted
