Damage factor

The destruction of the ecological balance of the factors of natural factors and human factors.Gaosuibuyou Thailand poly bags
Natural factors such as floods, droughts, earthquakes, typhoons, landslides, tsunamis and other. Caused by natural factors of the ecological balance is destroyed as the first environmental problem. By the artificial factors that caused damage to the ecological balance is called the second environmental problems. Human factors are the main reason resulting in the ecological balance. Human factors are mainly the following three aspects:
Environmental factors have changed

Such as the production of human life and activity generates large amounts of waste gas, waste water, waste, and constantly released into the environment; human resource unreasonable use or predatory use, such as blind wasteland, deforestation, water too confining,plastic bags supplier
grassland overload, will cause the deterioration of environmental quality, produces immediate or long-term effect, make ecological imbalance.
The species change

In the ecosystem, blind a species increases, make it possible for the balance of the ecosystem is destroyed. For example, the United States in 1929 was" blue canal, the inland river and marine communication, resulted in the lamprey into inland river, the trout an annual output of 20000000 kg. To 5000 kg, serious damage to the Inland Fisheries resources.
In an ecological system to reduce a species may also make the ecological balance is destroyed. Nineteen fifties Chinese has a large number of killed sparrow, resulting in some areas pest severity. Investigate its reason, lies in the pest natural enemy pest killing sparrows,solar module cell loss of natural suppressor factor.

The destruction of biological information system
The biological rely on each other between the contact information can maintain its cluster and normal reproduction. The person to the environment to cast a substance, interfere with or disrupt the biological information, make it possible for ecological balance disorders or destroyed.
For example, many insects by the release of sex hormone inducement of adult male mating, if it is discharged to the atmosphere pollution and chemical reactions occur, then the female sex hormone will lose the lure of male physiological activity, the result is bound to affect the insect mating and reproduction, finally leading to population decline and even disappear.
