COP25 climate change conference: What are you giving up for environment?
As the annual COP25 climate change summit continues in Madrid, we asked delegates from all over the world how they were adapting their lives for the sake of the environment.

What it was like on a boat with Greta Thunberg

Two Australian sailors gave the activist a lift back to Europe
Greta Thunberg, the 16-year-old climate change activist, is due to speak at the COP25 international climate talks in Madrid.  She doesn't travel by air, preferring to use more climate-friendly boats and trains.  

She hitched a ride with two Australian YouTubers who sailed with her from the US to Portugal on their catamaran.  

Riley Whitelum and Elayna Carausu post videos about their global travels by boat with their baby son, and were happy to have Greta and her dad on board.  We spoke to them about the 20 day voyage.
