What Anthropogenic activities caused the 6th Mass extinction (Video)
This is working secretly. We really don’t know. Watch how are doing the worst on our Planet Earth.
What happened before the Present-day mass extinction or sixth mass extinction or called the anthropogenic mass extinction?
How did dinosaurs extinct 66 million years before?
Dinosaurs once lived on Earth. We all know that. Dinosaurs lived on Earth 6.6 million years ago and were wiped out by meteorites from outer space or volcanic eruptions in the Deccan Trap in India. Whatever the reason for it.
The Permian extinction occurred before the extinction of the dinosaurs, about 25.2 million years ago. Among the land animals that lived in the Permian period were Dicynodonts, Lystosaurus, etc. They are herbivores. The Permian mass extinction, the mass extinction of the dinosaurs, has occurred five times since prehistoric times.
The sixth mass extinction/ anthropogenic mass extinction (Video) already began.
Scientists have shown that the sixth mass extinction has already started on Earth due to global warming, man-made factors, changes in the environment due to the advancement of science and technology, and other reasons. Scientists have named it the sixth mass extinction or Holocene mass extinction or Anthropogenic mass extinction.
In 2000, Paul Kratzen and Ujzen Stormer named this new geological epoch the Anthropogenic Epoch. Because at this time human activities are already affecting the earth’s environment. After that, other scientists responded and unanimously accepted this name. The effects of global warming on the environment have been realized since the 1800s.
There are approximately 5 million species of animals and plants in the world, of which scientists have given names and detailed descriptions of one and a half million (1.5 million) species. Currently, close observation of 5% of these 1.5 million animals shows that 26% are mammals, 41% are amphibians, 63% are cycads, 34% are conifers, 33% are marine corals, 13% are birds, and 31% are sea urchins. , 31 percent of crabs and 28 percent of freshwater prawns are at high risk of extinction.
An index from Living Plants says that those species have declined by 52 percent between 1970 and 2010. That is, 50 percent of the world’s observed waters have decreased in 40 years, which is very significant. About 50 percent of tropical forests have been destroyed.
If deforestation continues at this rate, 48,000 animals per million species will become extinct every decade by 2060.
Global fossil fuel burning increased by 29 percent from 2000 to 2008 and 41 percent from 1990 to 2008. The statistic also shows that 2000 years ago the population of the world was 300 million, 1000 years ago it was 31 million, but 260 years ago the population of the world was 79 million. Since the middle of the 17th century, the world’s population has increased by approximately 7 billion.
The current population of the world is 750 million. By 2050, the world’s population will stand at 9.7 billion. As a result, there will be a huge pressure on the earth. Animals will also be in danger. The occurrence and destruction of life on earth is a natural law.
What is the rate of anthropogenic mass extinction than the old five mass extinctions in the history of the earth?
Just like that, the sixth natural mass extinction has already begun, with man-made causes added to it. The advancement of man-made technology and increasing global warming have made the present world a lot of concern. That is why scientists have warned that the rate of extinction of animals in the sixth extinction is comparatively faster than the extinction of animals in the past five mass extinctions in the history of the earth.
All past mass extinctions were directly related to the global warming graph. Earth’s most destructive mass extinction, the Permian Triassic mass extinction, the rate of increase in global temperature was zero decimal zero zero zero two (0.0002) temperature degrees Celsius per year compared to the sixth mass extinction, calculated from 1800 to 2022. The rate of temperature increase is 0.02 degree Celsius per year which is more than 100 times increase.
Anthropogenic extinction examples:
It is true to think that the Earth has already lost many species due to this extreme temperature rise. Among them, an animal called Dodo, various species of fish, reptiles, amphibians, birds, and mammals are also lost in the I list. Extinct animals can no longer be seen on Earth, they are gone forever.
What are the Anthropogenic activities causing the extinction:
Human activities on Earth today are accelerating this extinction process. The geological age of the earth and the age of human life can never be compared because we cannot see the growth of our fingernails, so we cannot see the extinction of animals with our own eyes. Just understand the information from the statistics. So people have to be alert now to save the earth from the sixth extinction. Global warming must be prevented and man-made causes must be avoided to accelerate this change to save humanity from the sixth mass extinction.
The current world is already beginning to face the sixth mass extinction. Earth is now losing its biodiversity. A study has found that 1 million animal and plant species are at risk of extinction due to human-caused deforestation, greenhouse gas emissions, overfishing, and poaching. Other important risks include human-caused climate change, environmental pollution, etc.
When did the 6th mass extinction start:
Current mass extinction rates are higher than at any time in the past. If this situation continues, the world will face a mass extinction in the next 500 years, scientists have warned. Now we see only certain species of animals around us. Which cannot keep biodiversity normal in the environment. Because every animal is dependent on the other. The food cycle will break. The normal rule is that larger animals consume smaller animals as food. Now humans have increased the production of small animals with the help of such technology which is a threat to the fauna in the near future.
Climate change is a long-term risk. The large-scale volcanic eruptions of the past are doing the damage humans were doing by burning fossil fuels and releasing excess carbon dioxide. As of 2018, humans have emitted 1,400 times more carbon dioxide than was emitted during the Permian-Triassic mass extinction in Siberia. Statistics show that humans are emitting greenhouse gases at a higher rate, which poses a great threat to the environment.
