Global biodiversity loss is a major challenge. Since 1970, the number of birds, mammals, reptiles and amphibians has dropped by more than half and over a quarter of all species (one million animal and plant species) are now threatened with extinction (Brondizio et al. 2019). The extinction rate is now 1000 times faster than in pre-industrialization times, suggesting the advent of a sixth mass extinction (Barnosky et al. 2011).
