The bushmeat chain reaction The bushmeat chain reaction
As many of the parks and surrounding forests have lost 50–80% of their wildlife species, typically antelopes, zebras and other ungulates, the poachers are increasingly targeting primates including gorillas, bonobos and chimpanzees. A significant demand comes from bushmeat hunters to supply militias, refugee camps and mining and logging camps, where much of the work- force is forced. Thirty-four million people living in the forests of Central Afri...

Red Knot, distribution, breeding areas and migratory routes, by subspecies Red Knot, distribution, breeding areas and migratory routes, by subspecies
The red knot, Calidris canutus, is an example of a longdistance migratory shorebird. It has been the subject of extensive research worldwide including studies on its breeding cycle, winter ecology, and stopover sites. It is a typical representative of high Arctic shorebirds and is, therefore, a good indicator species for the whole group. As one of nature’s most prodigious travelers, it excites the interest of wildlife enthusiasts, scientists, and...

L’indice UV a l’echelle mondiale L’indice UV a l’echelle mondiale
« L’indice UV mondial (IUV) est une mesure simple du niveau de rayonnement UV à la surface de la Terre. Il a été mis au point de façon à indiquer les effets négatifs potentiels sur la santé et pour inciter les gens à se protéger. Plus l’indice est élevé, plus le danger d’atteintes à la santé et aux yeux est important, et plus le temps d’exposition suffisant pour représenter un danger est bref.

Le protoxyde d’azote : un coupable de premier rang après 2010. D’origine agricole pour l’essentiel Le protoxyde d’azote : un coupable de premier rang après 2010. D’origine agricole pour l’essentiel
« Nous avons calculé que le potentiel d’appauvrissement de l’ozone représenté par le N2O serait 50% plus élevé si le taux de chlore baissait à son niveau de l’année 1960. » Pour comprendre comment, selon Ravishankara, il est utile de savoir comment les CFC et le N2O attaquent l’ozone. Les rayons ultraviolets d’origine solaire scindent les molécules de CFC, ce qui aboutit à l’émission de chlore et d’oxydes de chlore. « Voilà ce qui détruit l’ozon...

The Arctic and the World - migration paths The Arctic and the World - migration paths
The Arctic plays host to a vast array of biodiversity, including many globally significant populations. Included among these are more than half of the world´s shorebird species, 80% of the global goose populations, several million reindeer and caribou, and many unique mammals, such as the polar bear. During the short summer breeding season, 279 species of birds arrive from as far away as South Africa, Australia, New Zealand, and South America to ...

Carbon Dioxide (CO2) emissions for selected African countries in 1997 Carbon Dioxide (CO2) emissions for selected African countries in 1997
Africa is very vulnerable to climate change given its low capacity to respond and adapt, but Africa emits relatively low amounts of greenhouse gases in comparison to other regions. This graphic shows the amount of carbon dioxide emissions per capita, in metric tonnes, in 1997 for OECD (Organisation for Economic Cooperation and Development) countries, for the world, for sub-Saharan Africa and for selected individual countries.

El Niño-Southern Oscillation (ENSO) Phenomenon El Niño-Southern Oscillation (ENSO) Phenomenon
El Niño describes 'the warm phase of a naturally occurring sea surface temperature oscillation in the tropical Pacific Ocean', and southern oscillation refers to 'a seesaw shift in surface air pressure at Darwin, Australia and the South Pacific Island of Tahiti'. This graphic explains the El Niño-Southern Oscillation Phenomenon, showing the differences between a normal year and an El Niño year.

Comparison between modeled temperature rise and observations of temperature since 1860 Comparison between modeled temperature rise and observations of temperature since 1860
Natural forcing (solar variation and volcanic activity) alone cannot explain the recent global temperature increase. This graphic shows the temperature anomalies (in degrees Celsius) that were expected to occur due to natural forcing only, from the year 1850 to the year 2000, according to climate models, and the actual anomalies that have occurred. The graphic also shows the expected and actual anomalies due to anthropogenic (human-caused) factor...

Who is involved? (The making of international legislation) Who is involved? (The making of international legislation)
Recognizing that industrial society must fix this major flaw in the system, governments and many forward-looking companies started exploring solutions as early as the 1970s. The strong activism of civil society organizations and the interest of the media in cases of toxic waste dumping were central in bringing the issue on the international agenda. By the 1980s, the international community launched treaty negotiations under the auspices of the Un...
