Explanation:

According to WWF’s Living Planet Report 2020, Global populations of mammals, birds, amphibians, reptiles and fish have suffered an average two-thirds decline in less than half a century due to environmental destruction.

• World lost 68% vertebrates in 1970-2016, according to the report.
• The Living Planet Report 2020 released by international non-profit World Wide Fund for Nature.
• The Living Planet Index (LPI), a measure of the state of the world’s biological diversity based on population trends of vertebrate species in terrestrial, freshwater and marine habitats, was used by the report to calculate this decline.
• The land-use change and the use and trade of wildlife were believed to have increased the planet’s vulnerability to pandemics, according to the report.

Hence both statements are correct.
