WWF’s Living Planet Report reveals two-thirds decline in wildlife populations on average since 1970

  • Causes include same environmental destruction - such as deforestation, unsustainable agriculture and the illegal wildlife trade - which contributes to virus outbreaks like COVID-19
  • WWF is calling for urgent action to reverse the trend by 2030 by ending the destruction of natural habitats and reforming our food system 

Global populations* of mammals, birds, amphibians, reptiles and fish have suffered an average two-thirds decline in less than half a century due in large part to the very same environmental destruction which is contributing to the emergence of zoonotic diseases such as COVID-19, according to WWF’s Living Planet Report 2020, released today.

The Living Planet Index (LPI), provided by the Zoological Society of London (ZSL), shows that factors believed to increase the planet’s vulnerability to pandemics - including land-use change and the use and trade of wildlife - were also some of the drivers behind the 68 per cent average decline in global vertebrate species populations between 1970 and 2016.

“The Living Planet Report 2020 underlines how humanity’s increasing destruction of nature is having catastrophic impacts not only on wildlife populations but also on human health and all aspects of our lives,” said Marco Lambertini, Director General, WWF International.

“We can’t ignore the evidence – these serious declines in wildlife species populations are an indicator that nature is unravelling and that our planet is flashing red warning signs of systems failure. From the fish in our oceans and rivers to bees which play a crucial role in our agricultural production, the decline of wildlife affects directly nutrition, food security and the livelihoods of billions of people.”

He added: “In the midst of a global pandemic, it is now more important than ever to take unprecedented and coordinated global action to halt and start to reverse the loss of biodiversity and wildlife populations across the globe by the end of the decade, and protect our future health and livelihoods. Our own survival increasingly depends on it.”

Commenting on report’s findings, Laila Mostafa Abdullatif, Director General at Emirates Nature-WWF said, “Today, more than ever before we urgently need to take action and work alongside organizations, governments and individuals to shift environmental patterns and help build a resilient future. This action is needed not only to bolster the economy but to also ensure future generations’ security. During this fast-evolving pandemic, we saw clear indications of the changes that can help us start to restore our environment if we let it stabilize.  At the root of this action is a fundamental change to our lifestyles.”

“Maintaining a healthy environment is central to maintaining our quality of life. It is vital that we address the factors that directly impact nature and people. We urge immediate global action to halt the losses our natural world is currently experiencing” continued Abdullatif.

The Living Planet Report 2020 presents a comprehensive overview of the state of our natural world through the LPI, which tracks trends in global wildlife abundance, and contributions from more than 125 experts from around the world. It shows that the main cause of the dramatic decline in species populations on land observed in the LPI is habitat loss and degradation, including deforestation, driven by how we as humanity produce food.

Endangered species captured in the LPI include the eastern lowland gorilla, whose numbers in the Kahuzi-Biega National Park, Democratic Republic of Congo have seen an estimated 87 per cent decline between 1994 and 2015 mostly due to illegal hunting,[1] and the African grey parrot in southwest Ghana, whose numbers fell by up to 99 per cent between 1992 and 2014 due to threats posed by trapping for the wild bird trade and habitat loss[2].

The LPI, which tracked almost 21,000 populations of more than 4,000 vertebrate species between 1970 and 2016, also shows that wildlife populations found in freshwater habitats have suffered a decline of 84 per cent - the starkest average population decline in any biome, equivalent to 4 per cent per year since 1970. One example is the spawning population of the Chinese sturgeon in China’s Yangtze river, which declined by 97 per cent between 1982 and 2015 due to the damming of the waterway[3].

The LPR 2020 also includes pioneering modelling which shows that without further efforts to counteract habitat loss and degradation, global biodiversity will continue to decline. Based on a paper, ‘Bending the curve of terrestrial biodiversity needs an integrated strategy,’ co-authored by WWF and more than 40 NGOs and academic institutions and published today in Nature, the modelling makes clear that stabilizing and reversing the loss of nature caused by humans’ destruction of natural habitats will only be possible if bolder, more ambitious conservation efforts are embraced and transformational changes made to the way we produce and consume food. Changes needed include making food production and trade more efficient and ecologically sustainable, reducing waste, and favouring healthier and more environmentally-friendly diets.  

The research shows that implementing these measures together rather than in isolation will allow the world to more rapidly alleviate pressures on wildlife habitats, thereby reversing biodiversity trends from habitat loss decades earlier than strategies that allow habitat losses and then attempt to reverse them later on.The modelling also indicates that if the world carries on with “business as usual”, rates of biodiversity loss seen since 1970 will continue over the coming years.

“These losses would at best take decades to reverse, and further irreversible biodiversity losses are likely, putting at risk the myriad ecosystem services that people depend on,” said David Leclère, lead author of the paper and Research Scholar at the International Institute of Applied System Analysis.

The Living Planet Report 2020 launches less than a week before the 75th session of the United Nations General Assembly, when leaders are expected to review the progress made on the Sustainable Development Goals, the Paris Agreement and the Convention on Biological Diversity (CBD). The UNGA 2020 will bring together world leaders, businesses and civil society to develop the post-2020 framework for action for global biodiversity and thus marks a milestone moment to set the groundwork for an urgently needed New Deal for Nature and People.

Lambertini said: “The Bending the Curve modelling provides invaluable evidence that if we are to have any hope of restoring nature to provide current and future generations of people with what they need, then world leaders must - in addition to conservation efforts - make our food system more sustainable and take deforestation - one of the main causes of wildlife population decline - out of supply chains.

“With leaders gathering virtually for the UN General Assembly in a few days’ time, this research can help us secure a New Deal for Nature and People which will be key to the long-term survival of wildlife, plant and insect populations and the whole of nature, including humankind.  A New Deal has never been needed more.”

Notes to Editors

  • *Using the data from 4,392 species and 20,811 populations, the 2020 global Living Planet Index shows an average 68 per cent decline in monitored populations. The percentage change in the index reflects the average proportional change in animal population sizes tracked over 46 years - not the number of individual animals lost.
