PARIS — Human societies need a radical overhaul to stop the destruction of the planet, according to the UN biodiversity expert panel's "transformative change" report released Wednesday.

The assessment, the second by the expert panel this week, says overconsumption in richer countries, a concentration of wealth and power, and a society increasingly disconnected from nature were driving ecological destruction.

It offered ideas of how to respond to "biodiversity loss, nature's decline and the projected collapse of key ecosystem functions."

Taking action will be difficult — but not impossible, the report said.

"It is not just governments. It is not just business. It is not just civil society. It is all of us. We all need to work together," said Arun Agrawal, one of the lead authors of the report from the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (Ipbes).

Here are three examples of successful transformations, big and small, according to Ipbes.

Sea bounty

In 2002 Spain suffered what was at the time its worst environmental disaster, when the Prestige oil tanker broke in two, spilling fuel that blackened swathes of the Atlantic coastline.

Fishing communities in Galicia responded to the devastation by pioneering a new way to manage a marine reserve, with fishers, scientists and the local authorities working together.

The "Os Minarzos" reserve model was "not without tensions," Ipbes said.

But more than 17 years later, the area has better fishing practices, more species and higher incomes — as well as improved trust and cooperation.

It also inspired new guidelines for the UN's agriculture body and a network of more than 20 million fishers in Europe and across parts of North and South America.

Ant Forest

China's largest private tree planting project, Ant Forest, is a mobile phone application that rewards users for climate-friendly activities.

The app boasts that 500 million people have used its program, which gives users "green energy points" for acts like walking or cycling to work instead of driving and cutting down on plastic and paper.

The points grow into a virtual tree, which Ant Forest matches by planting a real tree.

"Recognizing a wide range of ecological and social goals, the plants are suited to specific contexts and provide jobs in eco-agriculture and ecotourism in remote rural areas facing environmental degradation in China," the report said.
