Fighting climate change to preserve biodiversity Climatologists predict that in this century arid and semi-arid lands in Africa will expand. Deciduous trees will multiply due to evergreen trees. This evolution of vegetation will affect the course of rivers. The range of the elephant, although it covers a variety of habitats, will certainly be reduced.
At the junction of the Ganges and Brahmaputra deltas is the world’s largest mangrove forest. One hundred tigers from Bengal live there, relatively protected from the Man, for whom this territory is quite hostile. But the sea rises. 70% of the tiger’s habitat can disappear within 50 years, forcing these felids to take shelter in non-flooded areas where they inevitably come into conflict with humans. Although too often overlooked, the issue of the impact of global warming on biodiversity is crucial. Some species are directly threatened by habitat loss, such as polar bears, or their vulnerability to changes in their environment, such as amphibians.
But it is all biodiversity that will suffer from the effects of climate disturbance, species that are already threatened with extinction in other places or whose numbers are small and seem to be the most fragile. While climate change threatens biodiversity, conserving biodiversity is the most effective strategy to increase ecosystem resilience and reduce the risks that climate change poses to human society.
Take care of our home planet. That’s why, like never before, WWF mobilizes locally to maintain and restore ecosystems and habitats of endangered species, create marine or terrestrial protected areas, shelters and buffer zones … Your support remains important to help us solve the many global challenges warming.
Wild nature of the planet. This issue is all the more important because the conservation of biological diversity is our best advantage in mitigating the effects of climate change.
We are even concerned that climate change is becoming the primary factor responsible for biodiversity loss. Indeed, by the end of the century, average temperatures will increase as much as over the past 10,000 years, at such a fast rate that many species will not be able to adapt. Monteverdi’s Golden Toad and the Harlequin Frog, now extinct, are the first recorded victims of these shocks.
The fate of the polar bear gives an idea of the catastrophic consequences of global warming. Obeying the Arctic zone, the polar bear suffers from the depletion of its territory, pack ice. It is becoming increasingly difficult for him to feed himself, especially in summer, when the reduced ice cover makes areas where he can hunt seals inaccessible. Ocean warming and melting ice have already impaired plankton availability, forcing regular whales in the North Atlantic to migrate farther and farther away, resulting in a decrease in their reproductive rate. Other species, due to their biology and ecological, behavioral, physiological or genetic characteristics, experience great difficulties in adapting to even minor changes in the environment.
Heated water, at least one or two degrees, accelerates episodes of bleaching coral and, consequently, the death of entire reefs. In sea turtles, the sex of newborns is determined by the incubation temperature. Thus, global warming could increase the proportion of female turtles and jeopardize the renewal of generations. But we can say that all species, even those that have better adaptive capacity, will be affected by the effects of climate change.
Water and vegetation in the desert are rare. The African gerbil and kangaroo rat are pleased with the few drops contained in the seeds they consume, and their predators, hyena and jackal, the fluids accumulated in the body of these small rodents. Insects pick up morning dew. The scorpion is wrapped in an impermeable skin that prevents sweating. The dromedary can remain without drinking for ten days and lose up to 30% of its weight: its hump is a store of fat, which releases hydrogen, which in combination with environmental oxygen produces little water.
Endangered animals of the planet. Feneck bursts into the multi-tasking complex burrows that he digs under the dunes. His large mobile ears allow him to inflate. Large mammals, such as the gazelle, regulate their internal temperature with the help of suffocation, which causes local cooling of the oral cavity and brain.
