Why do you think invasive species are more of a problem in human altered biomes (anthromes) than they are in a biome that has not been altered by human activities?

invasive species are a problem both in anthropogenically altered and natural environments

Explanation:

An invasive species can be defined as a non-native species introduced into a new environment which then becomes abundant. Only in the US, it is believed that there are approximately 4,000 invasive species (some examples include the feral pigs, grey squirrels, European rabbits, etc.). In general, invasive species have a negative impact on the ecosystem, especially by displacing native species and thereby altering the trophic chain. In anthropogenically altered environments (anthromes), human beings are considered to be an invasive species.
