Detailed explanation-1: -Biodiversity loss is caused by five primary drivers: habitat loss, invasive species, overexploitation (extreme hunting and fishing pressure), pollution, climate change associated with global warming. In each case, human beings and their activities play direct roles.
Detailed explanation-2: -Our global food system is the primary driver of biodiversity loss, with agriculture alone being the identified threat to 24, 000 of the 28, 000 (86%) species at risk of extinction. The global rate of species extinction today is higher than the average rate over the past 10 million years.
Detailed explanation-3: -The WWF’s Living Planet Report 2022 finds wildlife populations have declined by an average 69% in the past 50 years. These six charts outline the scale of biodiversity loss-and what can be done to reach the nature-positive target.
