Biodiversity is the 'infrastructure that supports all life'

Dr Cristiana PaETMca Palmer, UN assistant secretary general and executive secretary of the convention on biological diversity, discusses Half Earth, a future biodiversity agreement and where to find the money to save life on Earth

Dr. Cristiana PaETMca Palmer has a big job ahead of her: planning the 2020 UN Biodiversity Convention in Beijing. As the Executive Secretary of the Convention on Biological Diversity (CBD), PaETMca Palmer is in charge of forming new goals with governments for the natural world post-2020. At the same time, a growing group of scientists are calling for a serious consideration of the Half Earth idea - where half the planet would be placed under various types of protection in a bid to prevent mass extinction.

Do you support the Half Earth model? What tweaks would you make to it?
