Swedish climate activist Greta Thunberg has called for changes to food production and consumption in a bid to tackle a trio of threats facing the world. “The climate crisis, ecological crisis and health crisis, they are all interlinked,” Thunberg said in a video posted on social media on Saturday to mark International Biodiversity Day. The focus on food and interlinked crises marks a new direction for Thunberg’s environmental activism, which has previously targeted fossil fuel policies and political decision-makers. Greta tackles disease, environment and emissions “The way we farm and treat nature cutting down forests and destroying habitats, we are creating the perfect conditions for diseases to spill over from one animal to another — and to us,” the 18-year-old activist said. “Millions have died from COVID-19, Zika, Ebola, West Nile fever, SARS, MERS, HIV-AIDS,” she said, listing zoonotic diseases that have jumped from animals to humans. The World Health Organization has said the coronavirus was probably transmitted from bats to humans through another animal. Scientists say 60% of the infectious human diseases that emerged from 1990 to 2004 came from animals.
