Around 200 protesters gathered beneath Rio de Janeiro’s world-famous Sugarloaf Mountain to protest against the ongoing construction of ziplines aimed at boosting tourism, alleging it will have an unacceptable impact.

The four steel lines will run 755 metres (almost 2,500ft) over the forest between Sugarloaf and Urca Hill, with riders reaching speeds of 62mph.
