To commemorate World Environment Day, Discovery Channel is airing a special series this Saturday that emphasises the need to strike a delicate balance between economic development and environment conservation.

The programme, to be aired from 12 noon to midnight, points to the fact that as our planet is fast running out of fresh water and with global warming and population explosion there would be less and less of this precious resource.

Climate change has altered weather patterns and caused less rain to fall in areas that need more of it.

The shortage of water is causing droughts, dust storms and fires.

Episode “One Water” presents the ways water has touched humanity around the globe, shedding light on the polarity of its abundance from those struggling to find water for basic needs to those thoughtlessly squandering this precious resource.

An amalgamation of visual sequences, expert commentary and hypnotic local music, the film signifies the importance of water to humanity. It has been filmed in 15 countries in both hemispheres.

Glaciers from the Himalayas' mountain range provide fresh water supplies to about 30 per cent of the world's population.

“Future World” showcases the importance of the mighty Himalayas to humanity.

“Surviving the Drought” shows up the condition of wildlife at the Ruaha National Park in Tanzania. Today the sparkling waters of Ruaha river are nothing more than a remote dream. A life-or-death quest for water has begun and the bewildered animals have no choice but to follow the dry riverbed upstream.

Taking viewers to America's last frontier is “Expedition Alaska”. The episode will highlight that this land of breathtaking diversity in terms of mountains, mighty rivers and rich wildlife is changing at a rapid rate. A team of scientists and wildlife filmmakers explore this remote and rugged landscape to document what impact global warming is having on the landscape and wildlife of Alaska.
