While some people argue that humans are not invasive species, due to a close reading of the definition, we can’t deny that may be more harmful to the environment than any other animal. In the last fifty years, human activities have drastically changed earth’s ecosystem in efforts to meet the increased demands of our ever-growing population. Invasive species are defined as, "a non-native (alien) species whose introduction to an area causes harm (environmental, economic or health)". Human activities are considered to be the most common ways invasive organisms are transported to new habitats. Asian carp refers to several carp species native to Asia including grass carp, silver carp, bighead carp, black carp, common carp and others. They can harm the environment, the economy, or even human health. Photo Credit: Georges Seguin Currently, 21 threats are listed, two-thirds of which are invasive species. In this top ten, we take a look at ten invasive species from the Global Species Database’s 100 most invasive species. These species are often invasive creatures that adversely affect the habitats they enter ecologically, environmentally, or economically. User: Why are invasive species dangerous to the environment? Not all non-native species are invasive. Invasive species have an adverse effect on native flora and fauna. An exotic species is any species, including its seeds, eggs, spores, or other biological material capable of propagating that species, that is not native to that habitat. Q: What are invasive species (also defines the terms “exotic” and “native”)? Due to the potential for damage by many non-native species, researchers have identified certain characteristics that can help predict a high level of invasiveness. For example, most of the food crops grown in the United States, including popular varieties of wheat, tomatoes, and rice, are not native to the region. An example of an invasive plant would be Kudzu, a native plant to Southeast Asia, which acts as an invasive species in the US. Invasive species can cause serious environmental harm in the area where they have been introduced. Asian Carp Photo Credit: Frank Vincentz. Under the Environment Protection and Biodiversity Conservation (EPBC) Act 1999, the federal government can list ‘key threatening processes’ and prepare ‘threat abatement plans’. The intervention of these species in a natural environment has become a major environmental problem. 4 This has given them a solid stronghold in the area.

An invasive species can be any kind of living organism—an amphibian (like the cane toad), plant, insect, fish, fungus, bacteria, or even an organism's seeds or eggs—that is not native to an ecosystem and causes harm. Invasive plants are no less dangerous for species survival, as they usurp water and soil nutrients. Learn more about invasive species, how they are problematic, and solutions for control.
