Can we reverse the biodiversity decline before 2050?

The observations are troubling and unmistakable: two thirds of the wild fauna has disappeared in less than 50 years. This shocking declaration of the World Wildlife Fund (WWF) is sounding the alarm, identifying the primary cause of this decline as human activity. It is approximately 4 000 vertebrate species, spread across 21 000 animals across the world that have disappeared following the destruction of their natural habitat, mainly for agriculture.
