EDMONTON, Alberta (Reuters) - Teenage climate activist Greta Thunberg joined thousands of protesters marching in Canada's energy heartland Alberta on Friday, as a smaller counter-rally led by a truck convoy of oil and gas workers also converged on the provincial capital Edmonton.
A crowd of several thousand led by indigenous drummers with students, young people and families marched slowly from a downtown intersection towards the Alberta legislature building. Many held banners and signs with slogans including "be a better ancestor". Police rode on bicycles at the front and back of the throng.
