Where in the world are invasive species mostly a problem

Answer 1

Invasive species are mainly a problem in regions where there have been human activities that have introduced non-native species to new environments. These regions include countries that engage in heavy trade and tourism, as well as areas that have experienced habitat destruction and ecosystem changes due to human development. Some of the regions that are particularly affected by invasive species include North America, Australia, New Zealand, South Africa, and various island nations.
