Bullying isn’t just something that happens on school playgrounds, it’s a daily occurrence in nature all over the world. Invasive species are plants and animals that, once introduced to a new habitat, start bullying the native species to the point where they can no longer survive there. They’re generally hardier, consume more resources, and reproduce much faster than the species they compete with. And, since they are new to the environment, they have very few, if any, natural predators to keep them in check.
The introduction of non-native plants and animals to a new ecosystem will almost always results in environmental stress, degradation and sometimes even disaster for native populations. These are 10 of the most destructive invasive species the world has ever known.
