How to maintain ecological balance

Factors that destroy ecological balance include natural factors and man-made factors. Natural factors such as floods, droughts, earthquakes, typhoons, landslides, tsunamis, etc. The destruction of ecological balance caused by natural factors is called the first environmental problem. The destruction of ecological balance caused by human factors is called the second environmental problem. Human factors are the main cause of ecological balance imbalance. Human factors mainly include the following three aspects:

Changes in environmental factors

< p> For example, human production and living activities produce a large amount of waste gas, waste water, garbage, etc., which are continuously discharged into the environment; human beings make unreasonable or predatory use of natural resources, such as blind land reclamation, deforestation, water surface overflow, grassland Overloading, etc., will deteriorate the environmental quality, produce short-term or long-term effects, and cause the ecological balance to become imbalanced.

Changes in biological species

In the ecosystem, blindly adding a species may lead to It damages the ecological balance. For example, the Welland Canal built by the United States in 1929 connected the inland water system with the ocean, causing lampreys to enter the inland water system, reducing the annual trout production from 20 million kilograms to 5,000 kilograms, causing serious damage. The loss of inland aquatic resources. Reducing one species in an ecosystem may also destroy the ecological balance. In the 1950s, China hunted a large number of sparrows, resulting in serious insect infestations in some areas. The reason is that the natural enemy of the pest is the sparrow. When being hunted, pests lose their natural inhibitory factors.

Destruction of biological information systems

Only by information contact between organisms can they maintain their clustering and normal reproduction. The artificial release of certain substances into the environment interferes with or destroys the information connection between organisms, which may cause the ecological balance to become imbalanced or destroyed. For example, many insects in nature secrete and release pheromones to induce mating of male adults of the same species. If the pollutants emitted by people into the atmosphere can react chemically with them, the sexual pheromones of female insects will lose their physiological activity in attracting male insects. As a result, mating and reproduction of insects will inevitably be affected, and eventually the population will decline or even disappear.< /p>

Therefore, primary school students should carry out some activities with the main purpose of protecting the environment and saving water, such as storing water after washing at home so that it can be reused for flushing the toilet. Water after washing vegetables can also be used to store water for this purpose. Purpose. Try to persuade parents and relatives and friends to take buses less and go for bicycles. Try to be unambiguous about small things, such as not throwing garbage everywhere and trying not to damage the small trees on the roadside. It is an important guarantee for our normal breathing. If you have time Go to the mountains with other students or your parents to plant saplings and other activities. Do not harm the beneficial birds or other beneficial insects and animals around you. It is best not to harm every grass and green scene around you.

Don’t destroy the ecology easily. Advise adults not to deliberately kill animals. The decrease of animals will increasingly destroy the ecological balance of nature. Hang up admonishment sentences in parks, flower and bird markets, etc., and talk about those animals. Our benefits, the natural disadvantages of us harming animals,,, don’t judge the quality of things based on your own understanding and one-sided knowledge,,,
