Habitat loss:

Humans insist on knocking down eucalyptus bushland where koalas live and building housing and suburban developments. With houses and roads come cars and dogs, both of which are lethal to koalas. A case in point - Southeast Queensland in Australia used to be a vibrant koala corridor extending for hundreds of kilometres down the coast and inland, but human population explosion in the area has seen a drop of 67% in the koala population within the past decade.

Introduced predators:

When Europeans started settling in various parts of Australia, they introduced a variety of non-native predators, such as foxes and dogs, both domesticated and wild. Koalas are no longer safe to wander between the trees in their home range in suburban fringes; they are constantly at risk of being killed by dogs.

What is the human impact of lions?

The human impact on lions is significant, primarily through habitat loss, poaching, and conflict with livestock. As human populations expand, lion habitats are encroached upon, leading to reduced prey availability and increased encounters with humans. These interactions often result in retaliatory killings of lions to protect livestock. Conservation efforts are crucial to mitigating these impacts and ensuring the survival of lion populations in the wild.
