The SARS-CoV-2 virus at the origin of the Covid-19 pandemic is one ten-thousandth of a millimeter in diameter. How can such a microscopic organism have such an immense impact on global health?
Human damage to biodiversity is leading us into a pandemic era. A new report shows we must urgently transform our relationship with the environment.
Needed: less wild meat in cities, more wildlife experts in public health.

Illegal wild animal meat is found in cities right across the world and poses a very real threat of infecting people.
The US and its allies are demanding answers over how COVID-19 became a pandemic. But instead of pointing fingers at China, the inquiry should focus on scientific clues to help us thwart future disasters.
The pangolin, one of the most poached animals in the world, could have served as an intermediate host in the transmission of SARS-CoV-2 to humans.
Covid-19, like other major epidemics, is not unrelated to the biodiversity and climate crisis we are experiencing.
