An example of an ecological disaster in a forest, a real and concrete example of human destruction o

formation of lactomar eutrophication; mercury poisoning in Japan; Fluoride destroys the ozone layer; deterioration of the ecological environment of the Aswan Dam; the evil results of the application of "666" and "DDT"; The "greenhouse effect" of the planet

In 1934, the Black Storm in the western United States destroyed more than 4,500 acres of arable land; In 1963, a major storm occurred in the agricultural reclamation area of the former Soviet Union, destroying more than 300 million acres of land; The destruction of forests also led to the extinction of the ancient Babylonian civilization; The Thar Plain, between India and Pakistan, has been reduced to a desert due to deforestation, covering an area of 650,000 square kilometers; The deterioration of the ecological conditions in the Yellow River Basin in China stems from the destruction of forest vegetation in the upper reaches of the Yellow River, and the Yangtze River will become the second Yellow River. The deterioration of ecological conditions in the northeast forest area is mainly due to the unreasonable logging and over-logging of forests in the southwest and northeast forest areas.

forest pests and diseases caused by overhunting natural enemies of insects; In India, the killing of otters in large quantities has increased the number of diseased fish and reduced fish production; In Australia, where animal husbandry is developed, dung beetles are infested due to cow dung covering grasslands.

Forests are the largest distribution area on the earth, the most abundant ecosystem, known as the lungs of the earth, maintain the global ecosystem balance, have a variety of functions such as maintaining water and soil, purifying the air, regulating temperature, and improving climate protection species, and are an important guarantee for maintaining the ecological balance and security of the earth. However, if the forest area is reduced on a large scale, it will bring unimaginable disasters to human beings, will reduce air quality, and after soil erosion increases, it will cause global warming, make the temperature of the whole earth abnormal, cause various extreme weather, and make drought and flood unbalanced, and will cause a series of very serious consequences. Some experts have predicted that if there were no forests on the earth, human beings would never live for more than a year.

Now with the continuous development of the economy, the rapid development of various countries, the continuous indiscriminate felling of trees, indiscriminate sewage discharge, caused very serious environmental pollution, coupled with the occurrence of various disasters, land desertification also makes a lot of vegetation on the earth less and less, so that some animals and plants live in the environment is also more and more reduced, but also make the quality of the air worse and worse, so that the air we breathe is mixed with some harmful substances, such as sulfur dioxide, These will imperceptibly endanger everyone's health. And according to the data, the current rate of global deforestation and forest degradation is alarming, so measures must be taken to protect forest biodiversity.

If you want to protect the forest, in fact, you can start from our daily life, usually save water resources as much as possible, but also refuse some white garbage, as far as possible do not use disposable lunch boxes, chopsticks, plastic bags, etc., as long as it can reduce the amount of garbage, and can also reduce the production of plastic products, save a lot of raw materials, including some hydropower resources, usually in life should also cherish their own paper, for the use of paper, books and newspapers should be classified, cherish paper is also cherish the forest.

Finally, in the face of the large-scale reduction of forests, what we can do is to make timely changes, give the earth a green mountain and clear water, and make efforts for the long-term sustainable development of the earth.

This will expose humanity to many disasters, such as heavy rainstorms, tornadoes, sandstorms, mudslides, and so on. This is not conducive to ensuring the safety of human life, nor is it conducive to providing a livelihood guarantee for human beings. Therefore, this also tells us a truth, do not cut down trees at will in ordinary life, and must know how to protect the environment.

It will affect the ecological environment of human beings, and there will also be serious environmental pollution, which is not conducive to the development of the natural environment, will lead to the continuous reduction of organisms, and will also affect the climate, which may lead to global warming.

Changes in the climate, a decrease in oxygen, serious soil erosion, air pollution, and an increase in solar radiation will bring great disasters to human beings.

Human destruction of forests is a global problem. Forests are one of the most important ecosystems on Earth, absorbing large amounts of carbon dioxide, maintaining the oxygen cycle, and maintaining the ecological balance of the planet, while also providing food, water, and habitat. However, due to the continuous expansion of human activities, such as industry, agriculture, timber harvesting and population growth, it has led to serious damage to forest resources.

Over the past few decades, human activities have caused millions of forest deaths, and these have had far-reaching effects. Let me introduce you to a few real and specific events.

In Brazil's Amazon rainforest, many forest species in the region are already threatened with extinction due to overplanting and forest land destruction, which has led to increased deforestation, widespread illegal logging, clearing and burning of forests, and greenhouse gas emissions. Chihuahua, Canada, is on the verge of extinction, and the area of natural forest in the region has been reduced by 90%. The same problem is also faced in the Ural Mountains near Lake Eagle's Nest, where animal habitat has been severely damaged, leaving local mountain tree species extremely threatened.

In addition, the destruction of forests has led to many global problems, including climate change, droughts, floods, etc., which have had varying degrees of impact on human society. The sulphur dioxide released from the eruption of Mount Elbru Siz not only kills crops, but also causes floods and landslides, causing serious social and environmental damage to the local community. In addition, the devastating effects of the 2004 Indian Ocean tsunami were also heavily linked to global deforestation and human activities.

These events show that we need to take proactive measures to protect our forest resources.

To sum up, the excessive destruction of forests by humans is one of the main culprits that lead to environmental problems. We need to take proactive steps to protect our forests, including the rational use of forests, the prevention of illegal wildlife trade, and the expansion of rare species protection. Only in this way can we protect our environment and maintain ecological balance, thus making the planet a better place.

1396 Australian Hare Plague.

Australia originally did not have rabbits, and the colonists introduced European rabbits in the early days of Australia's development: Australia's warm climate and abundant pasture provided good living conditions for rabbits. Coupled with the lack of natural predators for rabbits in Australia, rabbits began to breed at an alarming rate.

A few years later, hare sightings could be found everywhere in the Australian grasslands. The disaster of hares is mainly manifested in two aspects, one is that the huge quantity consumes a large amount of forage, on the other hand, the hares dig holes and build holes everywhere in the grassland, destroying the roots of the pasture, causing a large area of degradation of the grassland, and seriously threatening the development of animal husbandry, and the output value of animal husbandry has begun to decline significantly. Australia** urgently calls for the killing of hares and funds incentives.

People began to use various methods to deal with hares, such as shooting, poisoning, setting traps, and so on. However, due to the sheer number of hares and the rapid reproduction, the results were ineffective. Just when people were helpless, scientists in Australia discovered a mosquito that can spread a deadly virus among hares.

The virus only causes fatal damage to hares and has little impact on other animals. Scientists began to breed the virus-carrying mosquitoes in large numbers in the laboratory. In the years that followed, the mosquito-borne virus spread rapidly throughout Australia, and the hare population gradually declined.

The so-called ecological disaster is the disaster caused by human beings through irrational development.

For example, since 2007, there has been an increase in extreme weather, snow disasters in '07, ** in '08, drought in '09, floods this year, etc. It is all directly or indirectly caused by human overexploitation.

At the beginning of the 20th century, the Kaibab Forest in northern Arizona was still lush and vibrant. There are more than 4,000 deer in the forest, and the vicious and cruel wolf is the great enemy of the deer. Theodore, USA.

Eager for the deer to be effectively protected, Roosevelt decided to establish a hunting reserve and ordered the hunting of wolves, and as a result, the deer population increased and the amount of vegetation that could be eaten by all the deer in the forest was drastically reduced. The herd of deer became hungry for a long time, and many deer died of disease. The number of deer has been greatly reduced.........

In the 50s of the twentieth century, a Japanese fertilizer company discharged untreated wastewater into the bay, and the whole flying water contained mercury harmful to the human body, which not only seriously polluted the sea surface and fish, but also poisoned people and animals who ate fish, and the first to get sick was the cat that loved to eat fish, and the cat went crazy after poisoning. Let them commit suicide by jumping into the sea. Within a few years, there was no trace of cats in the Bay of Waters area.

Later poisoned people also began to get sick. The symptoms are similar to those of cats, because they were unclear at the beginning, so people named the local place name "Minamata disease".

Someone lit a fire in the place of the woods, and all at once a large forest was set on fire, and burned a lot of trees, burned a lot of plants and animals.

Chopping down trees, littering...
