QUITO (Reuters) - Laughing as his cap flew off in the Andean highland wind, Pope Francis flew into Ecuador on Sunday to start a "homecoming" tour of South America, where he will champion the rights of the poor and the planet.
His visit to Ecuador, Bolivia and Paraguay - three of the region's poorest and smallest countries - is Francis' first abroad since his landmark encyclical urging an end to man's degradation of the global environment.
