Protecting biodiversity: a top priority

As COP 15 on biodiversity has begun in China and as a prelude to the launch of COP26 this weekend, CNRS Images presents the key points to better understand the importance of protecting biodiversity.

The fifteenth Conference of the Parties (COP-15) began online in October and will continue in China in April-May 2022. It brings together the 196 signatory countries of the Convention on Biological Diversity.

Already in September, the world’s leading environmental and biodiversity specialists met in Marseille, at the IUCN's World Conservation Congress. But what are the goals? To bring together and mobilise the global conservation network, discuss key and emerging issues, initiate new actions, establish and influence priorities for action and the global conservation agenda.

Indeed, biodiversity is disappearing at an ever-increasing rate, and almost no ecosystem is immune to the phenomenon. All scientific disciplines (biology, ecology, but also economics, mathematics and palaeontology for example) are mobilised to deal with this major challenge that affects us all, since protecting biodiversity is quite simply protecting our entire environment: each species that disappears is a potentially fatal blow to its ecosystem, which is itself interwoven into larger ones....

To mark these international gatherings, we invite you to (re)discover films and news stories that we have made about this topic in recent years. The series “Animaux en Danger” (Endangered Animals), for example, takes you to meet ten scientists working all over the world to better understand endangered species and their interactions with their ecosystems, on land, at sea or in the air. But you can also meet biologist Éric Karsenti, the CNRS 2015 Gold Medallist, who is behind the Tara Oceans Expedition, an ambitious and essential project to map marine biodiversity which is threatened more than any other. More surprisingly, the animals themselves can become researchers in their own way, like the West Indian turtles fitted with GPS trackers, cameras and electronic chips to help us understand their movements and feeding habits.

More generally, researchers are not alone: their role is also to make citizens aware of the living creatures around them, and of the need to provide these creatures with a habitat to foster their development. By becoming aware of the dangers that put pressure on biodiversity, everyone can help defend it.

Still little known, marine environments are threatened by human activities. As the United Nations Decade of Ocean Sciences for Sustainable Development (2021-2030) begins, the scientific community, political decision-makers, companies and civil society must work together now to protect and conserve these ecosystems. This exhibition has been produced within this framework, based on scientific results.

Intro

Most of the Amazon region is covered by a forest with a surface area of around 6 million square kilometres. It has existed for around 50 million years and has undergone major disturbances but never resetting like in our latitudes following the ice ages. 200,000 species have been identified there to date taking all groups together which gives an estimated total of 1.8 million.

Biodiversity "is life". There is an extremely rich diversity of living things which involves all environments and latitudes but remains relatively unknown. Biodiversity is essential for humans because it provides them with essential services (resources, ecological services, chemical and therapeutic innovations, feedback effect on changes, etc.). The main challenge for researchers is to understand the organization and dynamics of biodiversity and its role in how ecosystems function.

CNRS Images,

Our work is guided by the way scientists question the world around them and we translate their research into images to help people to understand the world better and to awaken their curiosity and wonderment.
