Bangladeshis tackle Sunderbans oil spill with sponges

Villagers in Bangladesh, South-East Asia, have used pots, pans and sponges to help clear thousands of litres of oil, three days after it spilled into a nature reserve.

The oil is threatening the Bangladeshi part of the world's largest mangrove forest

The oil spilled after a tanker carrying 350,000 litres collided with another vessel, spreading the oil across nearly 40 miles of waterways.Footage shows villagers scooping oil from rivers and birds covered in black liquid in the Sundarbans area.

African penguins close to extinction in the wild

They're a favourite attraction at any zoo, but in the wild, African penguins are at risk of extinction

The population of African penguins fell 70% between 2001 and 2013 and is continuing to decline.

With less than 18,000 breeding pairs left in the wild in South Africa, African penguins are an endangered species.

Every winter, hundreds of African penguin chicks, that have been abandoned by their parents foraging for food, are rescued by a rehabilitation centre in South Africa.

It's part of a project led by Bristol Zoo.

This year, African penguin chicks are coming in early and in their hundreds from the colonies.

The rehabilitation centre is already helping to care for 430 and this number is growing.

The water from the glaciers is used to generate hydro power and for irrigation.

Scientists say the glaciers have lost more than one-fifth of their mass in just three decades due to global warming.
