Reporter Mark Brazil travels the Sasan Gir sanctuary in India to report of the plight of the last lions in Asia.

With an increasing human population in India requiring more and more land for agriculture, the Asiatic lion was brought to near extinction.

In 1972 a sanctuary was set up and from a few lions the sanctuary holds about 30 individuals.

In the Caribbean, goliath groupers are huge, majestic fish from the Caribbean sea.

At up to 2.5m they are outsized only by the few remaining sharks and they are critically endangered across their range due to historical overfishing.

Goliaths are now strictly protected in Florida.

Helen Scales meets her first wild goliaths in the company of Dr Sarah Frias-Torres from ORCA (Ocean Research and Conservation Association) who is studying many aspects of these huge fish including a survey of scuba divers that she hopes will show that a goliath is worth more alive than dead.

Also in the programme - News from around the world with regular news reporter, Kelvin Boot, and updates on the activities of the Open University's iSpot.
