Living Planet Report 2022 is a joint endeavour of the World Wildlife Fund and Zoological Society of London.
There has been a 69 per cent decline in the global wildlife population between the years 1970 and 2018.
This does not mean that 69 per cent of individual animals across the world has declined.
The report analysed almost 32,000 populations of 5,230 species.
The Latin America and the Caribbean region, which hosts the Amazon Rainforest, witnessed the highest wildlife decline of 94 per cent between 1970 and 2018.
Africa recorded the second highest decline of 66 per cent during the same period, followed by the Pacific (55 per cent).
North America and Europe recorded lesser nature decline, falling by 20 per cent and 18 per cent respectively.
Freshwater species population declined by 83 per cent.
Mangroves continue to be lost to aquaculture, agriculture and coastal development at a rate of 0.13% per year.
Around 137 square kilometres of the Sundarbans mangrove forest in India and Bangladesh has been eroded since 1985.
