Animals and plants provide humans with everything necessary for survival, external - including fresh water, food, and medicines. | |
However, humans cannot get these benefits from individual species - a rich variety of animals and plants must work together. | However, humans cannot get these benefits from individual species - a rich variety of animals and plants must work together. |
Plants are also very important for improving the physical environment: cleaning the air, limiting rising temperatures and providing protection against climate change. | Plants are also very important for improving the physical environment: cleaning the air, limiting rising temperatures and providing protection against climate change. |

How many species are at risk of extinction? | How many species are at risk of extinction? |
It is normal for species to evolve and become extinct over time - 98% of all species that have ever lived are now extinct. | It is normal for species to evolve and become extinct over time - 98% of all species that have ever lived are now extinct. |
However, the extinction of species is now happening between 100 and 1,000 times more quickly than scientists would expect, external. | |
As a result, many scientists warn humans could be causing the "sixth mass extinction" on Earth. | As a result, many scientists warn humans could be causing the "sixth mass extinction" on Earth. |
The International Union for Conservation of Nature (IUCN) has kept a "red list", external of threatened species since 1964. More than 150,000 species have been assessed, and 28% are considered to be threatened with extinction. | |
The UN's biodiversity body - known as IPBES, external - estimates that at least one million plant and animal species are at risk of extinction. | |
But the threat of extinction varies enormously. For example, it is estimated that 40% of amphibians (a group that includes frogs and toads) are at risk, but 14% of birds. | But the threat of extinction varies enormously.

In addition, for some groups - such as insects and fungi - not enough species have been evaluated to be able to accurately assess the risk. | In addition, for some groups - such as insects and fungi - not enough species have been evaluated to be able to accurately assess the risk. |

In its most recent report, IPBES, external highlighted the damage done by harvesting, logging, hunting and overfishing. | |
Between 2001 and 2021 the world lost 437 million hectares of tree cover, external - 16% of which was primary forest. The destruction of mature forests, which have taken hundreds - if not thousands - of years to develop, can have a very serious impact on biodiversity, external. | |
Biodiversity loss is occurring worldwide, according to the WWF, external. | |
It says recent losses have been highest in Latin America and the Caribbean, where animal populations have declined by 94% since 1970, mainly due to habitat destruction and overexploitation. | It says recent losses have been highest in Latin America and the Caribbean, where animal populations have declined by 94% since 1970, mainly due to habitat destruction and overexploitation. |
The Natural History Museum in London, external says the UK is one of the most nature-depleted countries in Europe, and is in the bottom 10% globally. | |
The rate of climate change is also increasingly difficult for animals and plants to cope with, external, the UN warns. | |
It says that limiting global temperature rises to 1.5°C, external above preindustrial levels is important to prevent even greater losses of biodiversity. | |

The agreement - known officially as the Kunming-Montreal Global Biodiversity Framework, external - aims to "halt and reverse" biodiversity's decline by 2030, and for humans to live "in harmony with nature" by 2050 to deliver "benefits essential for all people, external". | |

There are 23 more specific targets for 2030, including mechanisms to sufficiently finance conservation projects. Governments and private organisations are pledging to give at least $200bn (£161bn) per year by 2030. | There are 23 more specific targets for 2030, including mechanisms to sufficiently finance conservation projects.

A study suggests the 2030 targets may already be slipping out of reach because the effects of climate change and habitat loss on animal populations have been underestimated. | A study suggests the 2030 targets may already be slipping out of reach because the effects of climate change and habitat loss on animal populations have been underestimated. |
