That sinking feeling

Article Abstract:

Mexico City is sinking at a rate of 5 to 40 centimeters a year because of over-exploitation of the city's water supply. In the late 18th century, trenches in the Guadalupe mountains drained lakes and extracted groundwater. When this happened, the clay deposits began to dry out and shrink, thus sinking the ground level and the city. The sinking has aggravated the growing sewage problems, and city planners are calling for improvements. Researchers believe that about one third of water consumption is a result of leaks in water pipes.

Peak practise

Article Abstract:

A photographer and guide realizes his dream to trek across the mountainous Hindu Kush region of Pakistan and Afghanistan, in spite of two previous attempts thwarted by bad weather and treacherous conditions. Rugged terrain, steep mountains, icy conditions and desolate surroundings made the crossing extremely difficult in all three efforts. Two years after the second failed attempt, the explorer and his crew reached the top of the Hindu Kush slopes, a height measuring almost 5,200 meters high.
