Why are island wildlife threatened by island wildlife?

Island wildlife is often threatened by invasive species, which can disrupt local ecosystems and outcompete native species for resources. Additionally, habitat loss due to human activities such as tourism and development further exacerbates these challenges. The isolation of islands also means that native species typically have fewer defenses against new predators and diseases, making them particularly vulnerable. As a result, many island ecosystems face significant risks to their biodiversity.
