"The author combines the ecological realities in China with his own perspective to show his observation and reflection on the ecological phenomenon of biological invasion, which is worth reading."

Ran says that invasive alien species introduced through human activity are a major driving force in the continuing decline of contemporary biodiversity, and the list of such species is growing longer. The biosphere of the planet we live in is becoming increasingly fragile and homogenous.

"These changes start with people, and will eventually come back to each of us in varying degrees. We should at least be aware of what is happening now in order to be able to respond appropriately," he adds.
