One fifth of animal and plant species are under the threat of extinction, a global conservation study has warned.
Scientists who compiled the Red List of Threatened Species say the proportion of species facing wipeout is rising.

The report is being launched at the UN Biodiversity Summit in Japan, where governments are discussing how to better protect the natural world.
