LONDON (Reuters) - Swedish activist Greta Thunberg said on Thursday the world needed an economic overhaul to have a chance of beating climate change and that countries should be prepared to tear up old deals and contracts to meet green targets.

The 17-year-old spoke to Reuters TV after she and other activists sent an open letter to European leaders urging them to take emergency action and saying people in power had practically "given up" on searching for a real solution.
