Greta Thunberg aims to change how food is produced

Swedish climate activist Greta Thunberg has set her sights on changing how the world produces and consumes food in order to counteract a trio of threats: carbon emissions, disease outbreaks and animal suffering. In a video posted on Twitter yesterday, Thunberg said the environmental impact of farming as well as disease outbreaks would be reduced by changing how food was produced. "Our relationship with nature is broken. But relationships can change," Thunberg said in the video marking the International Day of Biological Diversity. Thunberg said the spillover of diseases from animals to humans was caused by farming methods, adding that a move to a plant-based diet could save up to 8 billion tonnes of CO2 each year.
