Risks of extinction hover over a third of Africa's tropical flora
West Africa, Ethiopia, Tanzania and southern DRC are exposed to the greatest pressures, according to the first assessment carried out on a continental scale.


By Laurence Caramel 20 Nov 2019 lemonde

Nearly a third - 31,7% - of the African tropical flora is threatened with extinction, according to a study published Wednesday November 20 in the journal Science Advances, which provides the first assessment carried out on a continental scale on the subject. West Africa, central Tanzania, Ethiopia and the southern Democratic Republic of the Congo (DRC) are identified as the regions where the greatest pressures on biodiversity are exerted, with risks. of extinction which can exceed 76% in the Ethiopian mountains or 67% in the interior delta of Niger.

Compared to fauna, the vast majority of mammal and bird species of which have been listed and classified on the red list of the International Union for Conservation of Nature (IUCN), plants remain the poor relation of this planetary surveillance. , despite the role they play in the sustainability of ecosystems.

Still present in 2020, these 5 species could disappear before 2030

by Brice Louvet, January 3, 2020

As we enter a new decade, it is important to remember that some iconic animal species may not survive the next. Poaching, loss of habitat and bycatch are at issue here.

Human activity threatens survival of wildlife, study finds

AFP • 01 / 02 / 2021

Forced to move further to escape the consequences of human activity, the survival of many wildlife is threatened, according to a study released Monday.

United Nations biodiversity experts warned in 2019 that more than three quarters of the land and 40% of the world's oceans have already been "seriously degraded" by humans.

But there are relatively few studies looking at specific species and how humans change their behavior.

For this study, published in the journal Nature Ecology & Evolution, Australian researchers investigated the consequences of activities such as road building, tourism, recreation, hunting, transport and fishing on 167 species, ranging from a 0,05 gram butterfly to the two ton great white shark.

And according to them, most species have increased the distance they travel by 70% on average because of humans. For a third, these movements have increased, or decreased, by half.

"This tells us that humans largely impact animal movements, but generally it goes unnoticed and nothing is being done," lead author Tim Doherty of the University of Sydney told AFP. .

“Usually, we only see animals in nature for short periods of time and we don't fully understand their movements and the space they use,” the researcher continues.

However, many species, including most mammals, spend almost all of their energy finding food and breeding partners. The extra energy they need to move away from humans therefore complicates their survival, he explains.

Among the animals studied, birds and insects moved more to avoid coming into contact with humans.

The study warns of "cascading consequences" on natural processes such as pollination if these movements were to continue at a sustained rate, with "potentially profound impacts on populations, species and ecosystem processes" .

Researchers call for better preservation of natural habitats by increasing protected areas, but also to regulate construction and tourism, and to limit seasonal hunting during breeding periods.

“Okapis, gorillas, giraffes… Kinshasa is a paradise for traffickers of endangered species. In this sprawling capital where everything is negotiated, the informal economy and crime intermingle and merge. So the trade in okapi skins is not really moving. Ditto for elephants, hippos, Kordofan giraffes, bonobos and pangolins, which are already among the species seriously threatened with extinction in the DRC. In Kinshasa, it takes $ 50.000 for a living gorilla, from 1.000 to 3.000 for a bonobo. A kilogram of pangolin scales sells for $ 50, four or five times more for ivory. "

Komodo dragons, sharks, rays ... The "red list" of endangered species updated

In total, the latest edition of this real barometer of the state of life on our planet lists 138.374 species, of which 38.543 are classified in the various “threatened” categories. Or some 28%. “These Red List assessments demonstrate how closely our lives and livelihoods are linked to biodiversity,” said IUCN Director General Bruno Oberle.

But he also said at a press conference that this update showed that "if states and other actors adopt the right measures, it is possible to turn the situation around" for some species. However, "nature is in danger", insisted Jane Smart, director of biodiversity at IUCN, hoping that "the entire planet will move towards sustainable management". The IUCN Congress is an opportunity to multiply the messages on the link between the ongoing collapse of biodiversity and human activities and living conditions on a planet also threatened by climate change.

Absolutely, that's crap. News on nature's enemy of man is everyday.

I learned today that an apparently harmless mushroom, the false morel, consumed for years in France, is at the origin of cases of Charcot's disease in its places of consumption, as well as a plant of Guam Island:

"As an environmental cause is suspected, all possible avenues are explored: traces of bacterial toxins or lead in the water, radon gas in homes, pollution of the air or the earth by pesticides or metals. heavy ... in vain.
Stalled, however, the researchers drew the attention of Peter Spencer, a toxicologist at the University of Oregon in the United States, who has previously investigated a similar situation on the island of Guam in the west. of the Pacific. The seed of a local plant, the Japanese cycad (or "small branch" in the West Indies) traditionally consumed had been shown to be the cause of many cases of ALS.
"

Charcot's disease here is not by lead, not by pesticides, not by heavy metals, it is by nature, by the same junk that we found in a fungus and in a seed.

The only acceptable nature is the boot. We control it, we shape it, we put it at our service. Let us not forget that nature does not give a damn about us: it is blind, its principle of evolution and selection based on chance, it is "walk or die". Only a primitive animist can make a goddess of her.
