Lake Titicaca is the largest lake in South America ... but for how much longer?

Located nearly 4,000 metres above sea level on the border of Bolivia and Peru, Titicaca has sunk to its lowest levels in 60 years and is believed to be evaporating at a rate of two to three centimetres a week.

Al Jazeera's Teresa Bo travelled to the lake to find out what the change means for the community who live around it and if anything was being done to deal with the problem.
