Humans risk living in an empty world, warns UN biodiversity chief

Ahead of the World Economic Forum, Elizabeth Maruma Mrema urges governments to take definitive action on climate, deforestation and pollution

Humanity will have given up on planet Earth if world leaders cannot reach an agreement this year to stop the mass extinction of wildlife and destruction of life-supporting ecosystems, the United Nation's new biodiversity chief has warned.

Elizabeth Maruma Mrema, the acting executive secretary of the UN Convention on Biological Diversity, has implored governments to ensure 2020 is not just another "year of conferences" on the ongoing ecological destruction of the planet, urging countries to take definitive action on deforestation, pollution and the climate crisis.
