In effect, we are currently responsible for the sixth major extinction event in the history of the Earth, and the greatest since the dinosaurs disappeared, 65 million years ago," the report states.The wide-ranging report also states that demand for resources globally exceeds the biological capacity of the Earth by some 20 percent. "Two thirds of the services provided by nature to humankind are in decline, worldwide," said Ahmed Djoghlaf, Executive Secretary of the U.N.'s Convention on Biological Diversity, in an open letter to all of the planet's citizens. "Humans have made unprecedented changes to ecosystems in recent decades to meet growing demands for food and other ecosystems services."
The average abundance of species declined 40 percent between 1970 and 2000 while species in rivers, lakes and marshlands have declined by 50 percent.
Between 12 and 52 percent of species within well-studied higher taxa including birds, mammals and amphibians are threatened with extinction.
In the North Atlantic, populations of large fish have declined 66 percent in the last 50 years.
Since 2000, 6 million hectares of primary forest have been lost annually.
In the Caribbean, average hard coral cover declined from 10 to 50 percent in the last three decades.
35 percent of the world's mangroves have been lost in the last two decades.
Biodiversity loss disrupts ecosystem functions, making ecosystems more vulnerable to shocks and disturbances, less resilient, and less able to supply humans with needed services.
Biodiversity loss has "weakened nature's ability to deliver its vital services," Djoghlaf writes. "Human activity is putting such strain on the natural functions of Earth that the ability of the planet's ecosystems to sustain future generations can no longer be taken for granted."
Technically we used to be the inferior ones, and dinosaurs rueld the earth. Imagine if that scenario were to happen in a few centuries from now.
