Examples of man-made destruction of ecological balance, talk about suggestions (essay)

An example of destroying ecological balance and being punished by nature Ecological balance is a dynamic balance. For example, individuals in a biological population are constantly dying and reborn, but overall, the whole population has not changed dramatically, so the system remains relatively stable. Once the ecosystem loses its balance, it will have very serious chain consequences. For example, in 1950s, China launched a campaign to eliminate the four pests of sparrows. However, in the years after sparrows were killed in large numbers, serious pests occurred, which caused great losses to agricultural production. Later, scientists found that sparrows eat a lot of bugs in nature. Sparrows disappeared, natural enemies disappeared, and insects multiplied. As a result, insect pests broke out, causing painful consequences of crop failure. Ecological balance is a dynamic balance that nature took a long time to establish. Once destroyed, some balances cannot be rebuilt, and the consequences may be irreparable by human efforts. Therefore, human beings should respect the ecological balance and help maintain this balance, and must not easily interfere with nature, resulting in this balance being broken. China has always taken "game" as its delicacy. In recent years, the eating and drinking style has become increasingly popular in society, and urban restaurants are scrambling to attract customers with "game", which has spread rapidly from southern coastal cities to all parts of the country. Many newly rich people boast about the "game feast". There are not only general wild animals on the menu, but also national first-and second-class protected animals. In addition, keeping wild animals as pets or making specimens for home decoration is becoming a new "fashion". Some city people like the wind of "game" and "wild things", which has aroused a vicious wave of large-scale killing of wild animals in rural areas. Because of the ban on guns, poisoning has become its main means. Not long ago, Shanxi Xinzhou Daily sent a message exclaiming that birds and animals were poisoned in the border area of Shanxi, Shaanxi and Mongolia, resulting in a serious situation that "there are no birds in the mountains and no beasts in the scenery"; In some provinces and cities, local wild animals have been eaten up, and a large number of wild animals have been illegally imported from other places and even abroad for restaurants. However, the entry of highly toxic wild animals into the market poses a serious threat to consumers' personal and environmental safety. There are also some domestication farms that buy and sell wild animals in the name of "legal" artificial farming. In fact, most of them are "real" wild animals directly captured or confiscated from the wild, covering illegal hunting and management. Scientists have found that many ethnic minorities have formed a unique culture in the long-term development of interdependence with nature. In those areas called "sacred mountains" by indigenous people, vegetation is rarely destroyed, and the most primitive state of biodiversity has been maintained. However, once this taboo culture is destroyed, the ecological environment often faces devastating disasters. Therefore, in the eyes of scientists, relying on local ethnic customs and traditional concepts is an important way to protect the ecology.
