    Australian scientists pushed on Monday to list the platypus as a vulnerable species after a report showed the habitat of the semi-aquatic native mammal had shrunk more than a fifth in the last 30 years. Severe drought brought by climate change, land clearing for farming and dam-building are to blame, said researchers at the University of New South Wales (UNSW) who made recommendations to government scientific panels.
