Why I build artificial glaciers

Sonam Wangchuk builds glaciers in the Himalayas to help local farmers collect water
Sonam Wangchuk is an engineer from Ladakh, a cold desert region in the Himalayas. He builds artificial glaciers - or 'ice stupas' - that collect water during the winter and melt during the spring. It's an invention that's helping thousands of local farmers and has led to the planting of more than 5,000 trees.

Mauritius: Pristine coastal areas 'will never be like they were before'

The MV Wakashio oil tanker split in two after running aground off Mauritius
When the oil tanker the MV Wakashio hit a reef off Mauritius, she was carrying 4,000 tonnes of oil. 

There's never a good place for an oil spill, but this was off a sanctuary known for rare wildife, and the island relies heavily on the income generated by the tourists visiting its pristine beaches. 

Most of the oil was pumped off the ship, but a small amount remains on board. Now the ship has broken in two.

Vassen Kauppaymuthoo an oceanographer and environmental engineer explains the effect of the disaster.
