Invasive Species

An invasive species is a non-native organism that causes harm to the environment, economy, or human health. These species are introduced to new environments either intentionally or accidentally, and due to their ability to reproduce and spread rapidly, they can outcompete native species and disrupt the balance of the ecosystem.

Examples of Invasive Species

Some common examples of invasive species include the zebra mussel, which has caused significant damage to ecosystems in the Great Lakes region, and the cane toad, which has had a detrimental impact on the native wildlife in Australia.

Effects on the Environment

Invasive species can have a range of negative effects on the environment, including outcompeting native species for resources, altering habitats, and disrupting food chains. This can lead to a loss of biodiversity and can have long-term consequences for the ecosystem.
