PICK OF THE WEEK: Global warming: Frogs under threat
A type of fungus that is deadly to frogs is being spread by global warming according to scientists. The chytrid fungus has killed many frogs in Central and South America and wiped some species out entirely. When the earth gets hotter more clouds gather over tropical regions. This creates conditions which make the fungus grow and spread very quickly. A third of all amphibians are currently under threat, with harlequin frogs and golden toads most harmed by the fungus.
