The world’s social and financial systems must undergo a huge transformation to revive the natural world that is vital for human life, a major UN report has concluded.
There should be an end to the focus on economic growth, international scientists warn.
They also say consumers in wealthy countries should waste less food, while world leaders should introduce urgent reforms including creating more green space in cities, bring in wildlife-friendly farming and curb wasteful consumption.
In the first comprehensive report on biodiversity by the UN, governments are also called on to:
restore habitats such as native forests
grow more food on less land
crack down on illegal logging and fishing
create marine protected areas
reduce pollution and the flow of heavy metals and untreated wastewater into the environment
The study, endorsed by 130 countries, including the US, Russia and China, sets out a framework for halting what has been dubbed the sixth mass extinction of life on Earth, from insects to plant life and fish. It is the strongest call ever by global scientists for action.
But the experts warned that “vested interests” such as energy giants and farmers that benefit from subsidies and lack of regulations would oppose changes to the status quo.
Species are being lost at an “unprecedented” rate – tens or hundreds of times more quickly than in the past, the report states.
Without “transformational change”, the damage will continue or worsen up to 2050 and beyond, directly threatening human wellbeing worldwide, the study says. It will also undermine efforts to tackle poverty and hunger, improve health and curb climate change.

Invasive species are the second biggest risk to global biodiversity
“Human actions threaten more species with global extinction now than ever before,” the report warns, estimating that “around 1 million species already face extinction, many within decades, unless action is taken”.
It warns that unless countries step up efforts to protect what natural habitats are left, they could lose 40 per cent of amphibian species, a third of marine mammals and a third of reef-forming corals within decades.
More than 500,000 land species do not have enough natural habitat left to ensure their long-term survival.
What we need now is massive, transformative and globally coordinated changes across all levels of society
The Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) study comes less than a week after UK government advisers issued an urgent call for radical steps to halt the climate emergency.
The study authors, meeting in Paris, identified industrial farming and fishing over the past 50 years as major causes of the collapse of nature, with extinctions being exacerbated by climate change driven by burning fossil fuels coal, oil and gas.
The clearing of forests for crops and livestock, expansion of roads and cities, cutting down forests, hunting, overfishing, water pollution and the transport of invasive species have used up three quarters of the world’s land.
Treat nature declines as an emergency, scientists tell world leaders
Environmental campaigners said the report must act as an emergency wake-up call and that people must rethink how to produce food.
“It’s absolutely vital that we urgently change the way we use the land and oceans to end this war against nature,” said Greenpeace UK’s executive director John Sauven.
He urged the UK government to plant millions of trees, provide ocean sanctuaries around coasts, restore peatlands and support a shift from meat and dairy to plant-based meals.
Alexandre Antonelli, of the Royal Botanic Gardens at Kew, said: “What we need now is massive, transformative and globally coordinated changes across all levels of society.
“[The study] confirms that we can’t just preserve, we must reverse the trend by increasing biodiversity locally, regionally, and globally.”
He warned that previous ambitious goals under the UN Convention on Biological Diversity that were due to be met by 2020 had been “almost a complete failure”.
He said: “We must learn from that process in order to not make the same mistakes. We just can’t miss this chance – lest it be our last.”
Lorna Greenwood, of Extinction Rebellion, said: “It’s time to rethink how we grow food, travel and look after the countryside.

15,000 scientific and government reports
The summary was approved by 109 nations
It looked at changes to nature over five decades, during which time the human population has doubled
“It may mean hard choices but the rewards are enormous.”
Labour leader Jeremy Corbyn said: “This is the sixth wave of extinction in our planet’s history but it is the first that is all our own doing.
“We made it happen and, with urgent action, we can stop it.
“To do so will require transformative changes to reprogram our whole economy so that it works in the interests of both people and the planet.”
Loss of mangrove forests and coral reefs could expose up to 300 million people to flooding
At least 680 species with backbones have gone extinct since 1600
559 domesticated breeds of mammals used for food have disappeared
85 per cent of the world’s wetlands have vanished since the 18th century
Five ways people are reducing biodiversity:
— Turning forests, grasslands and other areas into farms, cities and other developments leaving plants and animals homeless
— Overfishing the oceans: a third of stocks are overfished
— Permitting climate change to make it too hot, wet or dry for some species to survive. Almost half of land mammals and nearly a quarter of birds have had their habitats hit hard by global warming
— Pollution: every year, up to 400m tons of heavy metals, solvents and toxic sludge are dumped into waters
— Allowing invasive species to crowd out native plants and animals. Invasive alien species have risen 70 per cent since 1970
The findings are not just about saving plants and animals, but about preserving a world that’s becoming harder for humans to live in, said Sir Robert Watson, a British scientist and panel chair.
“We are threatening the potential food security, water security, human health and social fabric” of humanity, he said, adding that the poor in less developed countries bear the greatest burden.
“The report also tells us that it is not too late to make a difference, but only if we start now at every level from local to global,” he went on.
“Business as usual is a disaster.”
Sir Robert said economic capital was not the measure of wealth of the world – natural, social and human capital were better.
Habitat loss is one of the biggest threats, he believed. The report projects 15.5 million miles of new roads will be paved over nature between now and 2050.
Individuals can help with changes to how they eat and use energy, said ecological scientist Josef Settele.
Biologist Thomas Lovejoy, who has been called “the godfather of biodiversity”, said: “We can actually feed all the coming billions of people without destroying another inch of nature.”
It’s hoped the study will help shape new global targets on nature at a UN meeting in China next year.
