According to a new assessment by leading scientists, half of the world's population is supported by wild plants and animals.

According to a new UN report, nature is key to the livelihoods and survival of billions of people in developed and developing countries.

The study offers insights into how humans can more sustainable use resources from the environment, drawing on more than 6,200 sources, about 200 contributing authors and holders of Indigenous and local knowledge.

70% of the world's poor depend on wild species for medicine, energy, food, building materials, recreation and Indigenous cultural practices, according to a new study.

One in ten tree species are threatened with extinction due to unsustainable fishing and logging practices. Plants such as cacti, orchids and cycads are at risk, and unsustainable hunting is a threat to the survival of 1,341 wild mammals.

Lessons from sustainable practices can be found in the report.

One of the main drivers of the destruction of biodiversity is the exploitation of the Earth's natural resources. Climate change, increasing demand and the improving efficiency of technologies pose a significant challenge according to the new report.

Half of humans use and benefit from the use of wild species. They are essential for the preservation of the environment and for the well-being of humans.

The models for how we can have more sustainable use of wild species in the world we have compiled gives us a lot of hope.

The report shows the importance of local knowledge in ensuring the sustainable use of wild species.

Millions of people rely on the use of wild species to make a living. The protected areas received 8 billion visits a year and generated $600 billion. Billions of dollars are spent each year on the legal trade in wild plants.

The most important finding of the report was the importance of wild species to billions of people.

She said that the assessment made clear how important sustainable use of wild species is to human wellbeing.

It isn't just about the use of food for locals. The revenue generated from wild species is an important source of income and is an important incentive for conservativism.

One of the three pillars of the UN convention on biological diversity is the sustainable use of flora and fauna.

The lack of data about species that humans consume and exploit is an important limitation of the report, but the information included in it indicated that human practices were sustainable.

The story of Argentina was rewilded.

She said that that is a slightly different story to the one that we normally get told. It shows the need for better information.

Sir Patrick Vallance, the UK government's chief scientific adviser, said that the report provided compelling evidence that humans were overexploiting wild species.

The last decade did not meet its targets. He writes that a robust mechanism for monitoring progress and holding ourselves to account is needed. It's our chance to protect our planet.
