10,000 years. Because the pollution currently created by humans on the earth is relatively serious, it will take a long time to clean up, so it will take at least 10,000 years.

In 2018, there were 48.5 million tons of global e-waste, which is about the total weight of commercial aircraft manufactured by humans. Every year, about 5 trillion plastic bags are used in the world, covering an area of two Frances; Every year, an average of 2.1 billion tonnes of waste is generated globally, enough to fill 820,000 Olympic swimming pool ......
The degradation time of fruit peels and leftovers is shorter, 2 years for cigarettes, 5 years for woolen clothes, 50 years for cans, car tires, sports shoes, foam paper cups, leather products, etc., 200 years for aluminum beverage cans, and 500 years for plastic bottles; Glass jars and glass bottles take 2 million years.
In 2020, 1.6 billion discarded masks flowed into the ocean, which were originally life-saving and epidemic prevention items but brought great burden and damage to the ecology, and it took at least 450 years to decompose.
If everyone on the planet doesn't pay attention to it, doesn't restrain themselves, or makes regulations, and sees that those who litter their masks are punished to restrain those who don't have self-discipline, and distribute the money to those who take pictures to execute, I think the effect should be improved.
The use of our chemical plastic products, especially single-use plastics, should be drastically restricted, thereby reducing the demand for plastics and forcing companies to offer more environmentally friendly alternatives to these previously requested products. It is also necessary to intensify the work and develop a wide range of plans.
Finally, let's look at a fairy tale. Once upon a time there was a healthy creature called Earth, and all kinds of microorganisms lived in harmony within him. Later, a cancer cell called a car grew in the body, and they enslaved a microorganism called human to give them beauty and maintenance, provide energy, and pave the way.
The car is made of steel and iron, invulnerable, and everywhere it goes, the creatures are wiped out. But human beings have succeeded in turning into a virus that invades the brain of the car, using the car to spread and reproduce everywhere, and unites with the car in a vain attempt to destroy and transform the earth to rule everything. The earth eats volcanic pills, tsunami powder, and mountain gunpowder to destroy cars, but the more they are extinguished, the more prosperous they become.
The earth is panicking, and it is necessary to find out whether the ** mutation into a car, whether the relationship between people and cars is just a hermit crab, and whether their ultimate goal is not to destroy the earth, or to turn the earth into zombies who listen to them in the future, to invade other earths. Finally, in great fear, the earth died with the virus in order to protect the universe from infection.

The pollution caused by human beings on the earth includes plastic waste pollution, oil pollution and radioactive waste pollution, among which radioactive waste is the most seriously polluted and has the longest purification time, which takes tens of thousands or even hundreds of thousands of years to be completely purified.
-
Human beings are the masters of the earth, and if they do not cherish this homeland properly, they are creating pollution every day, and even causing permanent damage, and these pollution will not be completely purified until the earth is destroyed.
-
This takes a long time to purify, because human beings are destroying the earth all the time, putting a great burden on the earth.
-
Humans have been polluting the environment since ancient times. In fact, many years ago, people did not have the concept of protecting the environment, and often threw some messy things into the sea.
-
It was only in the industrial age that humans really began to pollute the environment. During the industrial period, emphasis was placed on the development of industry, but the protection of the environment was neglected.
-
From the 20th century onwards, the environment began to be polluted. Pollution is supposed to have started with the first industrial revolution, which has since destroyed the ecological balance of the earth.
-
Irrational treatment of sewage pollutes water resources. It takes many years to consume waste. Illegal logging, which has produced mudslides.

The planet Earth has existed for about 4.5 billion years, and this planet is actually a relatively mild planet compared to other nearby planets. However, this planet is not completely safe, at least for the past 4.5 billion years, it has been constantly changing and constantly testing the creatures that live on this planet. In the past 4.5 billion years, the earth has undergone dozens of biological changes, and the cruel environment of survival of the fittest has made the existence of creatures on this planet disappear again, and human beings may have to face this cruel fact one day.
Human beings have existed for 2.5 million years, and during these 2.5 million years, human beings have continued to evolve and evolve into what they are today. There have been many creatures before humans, the most well-known being the dinosaurs dating back 65 million years. Dinosaurs have dominated the earth for a relatively long time, they have dominated the earth for almost 100 million years, but even the dinosaurs that have existed on the earth for so long have almost perished in one day, leaving only avian dinosaurs to escape evolution.
There were other creatures before the dinosaurs, and the history of these creatures is even longer than that of the dinosaurs, but so far, there are only a few varieties of jellyfish and sponge creatures that can survive on this earth.
There have been so many mass extinctions on Earth that it is difficult to guarantee that we humans will not encounter them one day. To put it more seriously, a great catastrophe may be quietly coming, and it is still difficult to say whether humanity will be able to survive the next mass extinction by relying on its intelligence. So far, the only catastrophe scientists can budget is 1.1 billion years from now, and the source of that catastrophe lies in the sun on which we live.
Over the course of 1.1 billion years, the sun will continue to produce nuclear fusion reactions, and the hydrogen inside the sun will slowly turn into helium, and the core gravity inside will also collapse. The effect of this on the planet is that the surface of the earth will become hotter and hotter, and the radiation will gradually increase. After 1.1 billion years, the sun's nuclear fusion reaction will intensify, and the entire earth will be warmed up by solar radiation, and the surface temperature can reach as high as 70 degrees.
At high temperatures, the Earth's liquid water will evaporate, and humans will eventually die out due to the high temperatures and the disappearance of water sources.
This change in the ecological environment is predictable, at least human beings can be prepared at the same time, although there is still no corresponding way to deal with this catastrophe, but in 1.1 billion years, human technology is enough to support people to travel through space at will, and the sun will not become a threat to human life.
It is well known that the environment on Earth is the mildest, with distinct seasons throughout the year. It is a great blessing for humans to survive here, and to date, humans have been the dominant power on the planet for millions of years. Everyone has their own habits, and when they are tired, they will rest. >>>More
About 3 million to 3.5 million years ago, humans appeared on Earth. The prehistoric period of human history is the first stage of the development of human society, that is, the stage of primitive society. The vast majority of primitive society belongs to the Paleolithic Age, in which human beings went through the stages of Homo sapiens, Homo erectus, early Homo sapiens and late Homo sapiens, and finally completed the transformation from primitive man to modern man. >>>More
There is a conjecture that gravity is propagated by gravitons. >>>More
?This involves not only the strategy of sustainable development, the resources provided by the earth for the survival and development of human beings, but also the number of years in which the earth's external environment can be maintained. >>>More
Human beings are bacteria, the ability to reproduce is too strong, from a few people in the ancient centuries before, to today's seven billion, is the earth easy, the weight of human beings appears out of thin air, not natural resources like oil are the original mass of the earth. In order to build cities, human beings have moved the resources that are automatically allocated by the earth at will, resulting in changes in the interior of the earth's crust and the load-bearing of plates. >>>More
