WOBURN SANDS, England (Reuters) - Jude Walker, an 11-year-old boy, is on an odyssey he hopes will help save the planet: he is walking to London from northern England in a bid to garner support for a carbon tax to tackle carbon emissions.

Partly inspired by activist Greta Thunberg, Walker, from Hebden Bridge in Yorkshire, has braved hills, rain and doubts along his 210-mile trek to the British parliament in Westminster, central London.
