humans intentionally or unintentionally bring a creature into a new area, and if it is suitable for its survival and reproduction, its population will begin to increase and the distribution area will gradually expand, which is the process of ecological invasion. This process can sometimes have serious consequences. Such as the European rabbit into Australia, because there is no natural enemy constraints, soon in the grassland mass reproduction, they compete with cattle and sheep for feed, so that large areas of grassland barren, with the help of mucus tumor virus infection, only to control its population growth. The moles, native to North America and important fur beasts, rapidly increased their populations after their introduction to Europe, and soon spread throughout Europe, even into the Great River basins of Siberia and northern Russia in the Soviet Union, where they broke river banks and irrigation systems and were difficult to eradicate. Anchovies, native to tropical America, have been introduced to various parts of the world, causing harm to many waters due to their rapid reproduction, their growth and their particularly lush growth, and their difficulty in suppressing and eradicating them. Therefore, we should be cautious about the introduction of new species and consider the consequences of ecological invasion.
