Dans le cadre de l’initiative Call to Earth pour créer un avenir durable, les équipes de CNN se rendent à Svalbard, un archipel norvégien situé à mi-chemin entre la Norvège et le Pôle Nord, afin d’étudier comment les scientifiques cherchent à comprendre l’adaptation des ours polaires au changement climatique. Reportage.

Urbanisation croissante, agriculture intensive, surexploitation des ressources, introduction d’espèces exotiques et dérèglements climatiques : toutes ces modifications environnementales constituent un cocktail détonant pour la biodiversité. Face à ces transformations, des questions reviennent fréquemment : les espèces sauvages pourront-elles s’adapter à des changements aussi rapides et d’une telle ampleur ? Les adaptations observées permettront-elles

L’accès à de nombreux médicaments, comme des analgésiques courants ou des traitements anticancéreux, est menacé par la vague d’extinction de la biodiversité dans le monde. Car soixante mille plantes et champignons sont utilisés pour leur valeur médicinale. 40 % d’entre eux sont directement menacés d’extinction, mettant en péril nos approvisionnements

La déforestation en Amazonie brésilienne a augmenté de 55 % au cours des quatre premiers mois de l’année par rapport à la même période de 2019. La destruction a atteint l’année dernière son plus haut niveau en onze ans. Les tribus amazoniennes sont confrontées à de plus en plus de

Il ne se passe pas une semaine sans qu’une nouvelle étude nous alarme sur les dégâts que l’homme, les dégradations de l’environnement ou les dérèglements climatiques font peser sur la biodiversité. Le thème de l’extinction des espèces est devenu courant, on parle aujourd’hui de sixième extinction, d’accélération, de fin du

The cold-water coral reefs of Chilean Patagonia still reveal their secrets. But scientists say climate change and industry are impacting "one of the last wilderness areas on the planet". As part of the global 'Call to Earth' initiative to create a sustainable future, CNN

Sixty years ago, Tasmania's coastline was protected by a kelp forest so dense that it trapped local fishermen when they set out on their boats. These underwater forests, rich in giant algae tens of metres high, the "sequoias of the seas", are sanctuaries of

Do I have to say it again? The sixth extinction has already begun. Scientists tell us and say it again: this extinction is not due to a catastrophic natural event, but to man. The unnatural loss of biodiversity is accelerating, and if it continues, the planet will lose vast ecosystems and

On the occasion of the International Day for Biological Diversity celebrated on 22 May, whose theme this year is "Our Solutions are in Nature", UNESCO has posted on its website five exchanges between world-renowned experts in which they discuss the following topics

The life-crushing machine just went haywire with the coronavirus crisis. But the consequences that result from our lack of foresight make it necessary to alert and mobilize on the urgency of other dangers that have not disappeared during this pause for health reasons of the weather: global warming, disappearance, etc.

The coronavirus pandemic still raises many questions about its origin as well as its health impacts. Its complexity stems from its entanglement in a human ecosystem in the throes of upheaval: climate disruption, pollution, chronic diseases such as diabetes and obesity, which aggravate the effects of Covid-19. What's more, the pandemic

Only one species is responsible for the COVID-19 pandemic: ours. As with the climate and biodiversity crises, recent pandemics are a direct consequence of human activity, in particular our global financial and economic systems, which are based on a limited paradigm that values economic growth over the long term.

On April 5, the U.S. Department of Agriculture announced that a tiger at the Bronx Zoo in New York City was found to test positive for COVID-19, along with six other tigers and lions, with symptoms consistent with the disease. This detection of the new coronavirus in a wild animal is an important step in the fight against the disease.

The current coronavirus outbreak may not be an isolated, historic episode. For many ecosystem observers and public health specialists, the coronavirus epidemic is the emerging part of a much larger phenomenon: the succession of pandemic crises caused by the collision of the

Beijing has announced a "complete" ban on the trade and consumption of wild animals, a practice suspected to be at the root of the coronavirus outbreak that began in December in central China and now threatens the world with a pandemic. This announcement is good news for the advocates of

Since the end of the Second World War, and especially since 1981, a situation rent had been set up for the benefit of a club of a few agrochemical and agricultural giants such as Bayer and Monsanto, under the pretext of "ensuring security for users",
