It’s a real waste that we do with the planet Earth. We are destroying habitats without realizing the long-term consequences of biodiversity

Birds, fish, mammals, reptiles … Their population in the world collapsed by 58% from 1970 to 2012, warns the World Wide Fund for Nature (WWF). And this decline will continue if we do nothing, said the organization in its Living Planet Report 2016.

« What biodiversity continues its fall, and the natural world as we know it today will collapse in one piece, » warns Marco Lambertini, Director General of WWF International.
Concerned about falling wildlife populations, he believes it could increase to 67% within four years.
The situation is particularly worrying that threat in the wake of human life.
When the living disappears, it’s natural capital disappears. And if this natural capital is destroyed, we destroy our ability to live on the planet in the long term. Pascal Canfin, Director General of WWF France.
No fewer than 14,152 people belonging to 3706 vertebrate species were used to measure this development, with the help of the Zoological Society of London.
The numbers on the side of freshwater animals collapse with an average of 81% during 42 years observed. Overuse, sometimes involuntary, and habitat loss are behind this plague. Although the fall is less important at sea, overfishing endangers third of the species of sharks and rays. Terrestrial populations for their part tumbled 38%.

agricultural, forestry, mining extractions, urbanization: Human activities are often behind the deterioration of the habitat, the biggest threat to wild species.
For now, climate change have an impact « relatively marginal […] because it is only in one degree of warming, » compared to the preindustrial era, said Pascal Canfin.
If the climate continues to warm and brings its share of extreme weather events, the effects will be devastating for both humans and species and their habitats, warn researchers.
The climate conference in Marrakech, Morocco, is an opportunity for the international community to fulfill the promises made at the Paris conference last year, in particular to contain global warming to below 2 ° C.
Of the more difficult promises that humanity draws the equivalent of 1.6 times the planet’s resources and its population is increasing. If it goes from 7.4 to 9.7 billion in 2050 according to the same scenario, then we will need two planets.
« The consequences of human pressure on the environment is becoming better known and observed, » says the WWF, so that « there was no rational economic reaction. »
