What is the Sixth Extinction summary?
The Sixth Extinction Summary. In The Sixth Extinction, Elizabeth Kolbert studies the relationship between human beings and the environment, and concludes that human behavior is on the verge of causing (or may have already caused) a mass-extinctionthe sixth in the history of the planet.
What is known as the 6th extinction?
The sixth, which is ongoing, is referred to as the Anthropocene extinction. The five mass extinctions that took place in the last 450 million years have led to the destruction of 70-95 per cent of the species of plants, animals and microorganisms that existed earlier.
What is the sixth extinction according to Elizabeth Kolbert?
In lucid prose, she examines the role of man-made climate change in causing what biologists call the sixth mass extinction the current spasm of plant and animal loss that threatens to eliminate 20 to 50 percent of all living species on earth within this century.
What is the sixth extinction and what is the cause?
The ongoing sixth mass species extinction is the result of the destruction of component populations leading to eventual extirpation of entire species. Populations and species extinctions have severe implications for society through the degradation of ecosystem services.
What is the sixth mass extinction explain its causes?

Are we in the 6th major extinction?
The ongoing sixth mass species extinction is the result of the destruction of component populations leading to eventual extirpation of entire species. Populations and species extinctions have severe implications for society through the degradation of ecosystem services.
What will happen in the 6th mass extinction?
Earth is witnessing the sixth mass extinction event, a study has claimed. Led by University of Hawaii, the research blames human activities for the rapid deterioration of the number of species in the planet. They said that Earth has lost 7.5 to 13 per cent of its two million species – 150,000 to 260,000 – since then.
What is the 6th extinction event?
The Holocene extinction, otherwise referred to as the sixth mass extinction or Anthropocene extinction, is an ongoing extinction event of species during the present Holocene epoch (with the more recent time sometimes called Anthropocene) as a result of human activity.
What are the 6 great mass extinctions?
The ongoing sixth mass species extinction is the result of the destruction of component populations leading to eventual extirpation of entire species. Populations and species extinctions have severe implications for society through the degradation of ecosystem services.
