A 15-year-old vegan has blasted world leaders - saying their inability to act on climate change is stealing the future of children.

Greta Thunberg, a climate activist from Sweden, was speaking at last week's global climate change conference COP 24 in Poland. She was speaking on behalf of Climate Justice Now - a global network of climate activist groups.

According to reports, Thunberg has persuaded her family to go vegan and give up flying, saying: "For me none of this is a sacrifice, I don't need those things. I understand that some people see it as a sacrifice."

Speaking at the conference, Thunberg addressed world leaders and said: "You have ignored us in the past, and you will ignore us again.

"You say you love your children above all else, and yet you are stealing their future in front of their very eyes.

"You only talk about moving forward with the same bad ideas that got us into this mess even when the only sensible thing to do is pull the emergency brake. You are not mature enough to tell it like it is."
