Humans have introduced non-native species into new environments through activities such as trade, travel, and the pet trade. These introductions have had negative effects on biodiversity by competing with native species for resources, spreading diseases, and disrupting natural ecosystems. One example is the introduction of the cane toad in Australia, which has had devastating impacts on native fauna. Another example is the introduction of the European starling in North America, which has displaced native bird species from their habitats.
