Will there be a sixth mass extinction? What is the relationship between humans and the climate, livi

This possibility is not impossible, the more advanced industrial science and technology, the greater the threat to living beings, the exploitation of natural resources by human beings has reduced the living place of these organisms, human deforestation, animal hunting, are destroying the balance of organisms, human beings and organisms, climate are closely related, human changes to the environment, will inevitably bring various disasters to our lives.

The sixth mass extinction should not occur, the relationship between humans and climate organisms is mutually reinforcing, and only by protecting the ecological environment can humans live longer.

There is a good chance that it will appear. Human beings and these climates and organisms are actually complementary to each other, and whoever is missing is actually bad, but the impact in recent years is still very great.

I don't think the sixth mass extinction will happen, because the technology is very advanced now, and it is very difficult to have a mass extinction. I believe that the relationship between human beings, the climate, and living things should be one of harmonious coexistence.

Human beings and the climate are mutually fulfilling and changing existences, and human beings have caused the average temperature of the world to rise through their own industrial activities, and at the same time affect other life.

The big waves wash the sand, and the survival of the fittest.

In the last 100 million years or so, there have been five mass extinctions. The largest occurred 100 million years ago, annihilating 95% of all species. Throughout the past and present, scientists are taking lessons from previous mass extinctions for the present:

Living things are disappearing at an alarming rate, mainly due to environmental changes caused by humans. Many scientists believe that the Earth is experiencing a sub-mass extinction. Each previous mass extinction occurred when the Earth's carbon cycle was disrupted.

The carbon cycle is a natural process in which cellular respiration (the release of carbon dioxide) and photosynthesis (the uptake of carbon dioxide by plants) are interlinked. Today, humans are releasing carbon dioxide into the environment at an alarming rate.

<>According to a new article published in Science Advances, the increase in carbon dioxide in the oceans, home to most of the planet's plants and animals, could trigger mass extinctions similar to those seen in ancient times. This article puts the increase at 310 billion tons. According to the United Nations Intergovernmental Panel on Climate Change, we will reach that number by 2100, said lead author Daniel Rothman of the Massachusetts Institute of Technology.

The situation in the rest of the world is agnostic.

Whereas previous mass extinction processes lasted tens or even millions of years, we are now in a period of change that lasts at most a few hundred years, so it is difficult to compare. Many experts claim that the Earth is experiencing a sixth mass extinction, but this is still one"Scientific issues", said David Rothman, a professor of geophysics in the Department of Earth, Atmospheric and Planetary Sciences at MIT. He explained that once our planet crosses the threshold he outlined in **, quantitative change leads to qualitative change.

These changes are linked to previous mass extinctions on Earth.

"Rothman said"One of the striking things about the history of life and the carbon cycle is that whenever one big event happens, the other also happens. While each mass extinction is clearly characterized by a disruption of the carbon cycle, there is also evidence that at other times in Earth's history, the carbon cycle was disrupted, while most organisms did not become extinct.

What caused the sixth mass extinction. Analyze from a human perspective.

From the ancients to the present day, both in terms of wisdom and morality. We are not as wise as our ancestors, and you are not as wise as our ancestors. And more selfish, greedy, violent, at the beginning of man, the nature of goodness, very skinny simple sentences, and now how many people can do it, cruelty to animals.

Deprivation of the natural world. The Industrial Revolution has not paid off itself, but nature is accelerating the deprivation and appropriation of the earth's resources. Whether the earth is life or our mother home.

At least human beings have reached today's developed civilization, and they can be regarded as adults. Isn't it time to think about giving back to nature and protecting the planet first, but the truth doesn't seem to be so obvious. Instead, the planet is warming.

Pollution continues. Whether it is a sign of the extinction of life is not known. As a small person, I think it can be understood more simply, just like our current body, if you eat well and maintain your hands well, you will live a long and healthy life.

But if it is for one party to smoke, drink, and drink all kinds of pastimes. The human body can also age prematurely. So there is a cause and an effect.

Nature also has his power. It's just that people are fearless. Only let human beings experience it themselves.

Mass extinction refers to a large-scale extinction, in the history of the earth, there have been a total of 5 mass extinctions, the closest of which is 65 million years ago, the asteroid hit the earth caused by the dinosaur mass extinction event, so there are many friends who are worried, when will the sixth mass extinction occur, can human beings have a way to reverse this disaster?

1.Species extinction

A 2017 survey showed that half of the 27,600 vertebrate species have died out and a third are on their way to extinction. In addition to vertebrates, two-fifths of insects are also dying out. Birds, amphibians, mammals and reptiles have been dying out 100 times faster in the last century.

Researchers believe this phenomenon is a precursor to mass extinctions.

2.The density of seawater decreases

The density of the sea is decreasing, which has led to an annual increase in sea levels, which have risen by nearly 20 centimetres worldwide since the last century, leading to the inundation of low-lying areas, most severely Tuvalu in the Ellis Islands, which relocated to New Zealand in 2001 because of the imminent inundation of the country. Not only humans have been affected, but many animals have also lost their habitats due to rising sea levels.

3.Glaciers melt

Greenland lost 600 billion tonnes of ice last year alone, and this century is melting a third faster than the last century, and since 80% of the area is covered with snow and ice all year round, when it all thaws, it will cause global sea levels to rise by meters. It will be a fatal blow to all coastal cities and island nations.

4.Forests are decreasing

The Amazon forest has the reputation of "the lungs of the earth", covering an area of 5.5 million square kilometers, due to the large number, it can convert a large amount of carbon dioxide into oxygen, but unfortunately in the past 50 years, there have been many fires here, and a large number of trees have been cut down, resulting in the destruction of 10,000 square kilometers of forests, not only the Amazon, but also forest trees around the world disappear every year for various reasons, covering an area of up to 72,800 square kilometers.

5.The sea heats up

The greenhouse effect not only affects the temperature of the atmosphere, but also raises the temperature of seawater, which will cause storms in the ocean to be more violent, and seawater will go deeper into the land at high tide, threatening the animals and plants living along the coast, and some animals and plants in the sea will die because they do not adapt to the temperature, breaking the food chain and affecting the entire ecological environment.

All of these five phenomena are caused by human activities, and if left unchecked, many organisms will gradually die out by 2070, and it will take at least 3 million years to restore the current biodiversity. Before the first five mass extinctions, the earth has given some warnings, similar to many current phenomena, so if you want to completely avoid mass extinctions, it is still the same sentence, take good care of the environment, reduce damage and pollution to the environment, and do not overexploit resources or anything.
