Apart from the actual eucalyptus leaves themselves, no other living things are affected by the koalas eating leaves which are toxic to only some species.
Koalas are not bears. Koalas are grazing animals, spending most of their waking hours in the trees, eating eucalyptus leaves. They grasp the leaves with their "hands" which have opposable thumbs.
Koalas eat a diet of eucalyptus leaves. Most animals are unable to do this because the leaves are poisonous. The back molars of Koalas are also different, in that they are shaped to permit cutting and sawing.
Koalas will not eat anything poisonous. They only eat certain types of eucalyptus leaves and blossoms, none of which are poisonous to koalas although they are toxic to many other animal species.
None, because koalas do not eat "everything". Koalas feed almost exclusively on gum (eucalyptus) leaves and flowers. No other animal can eat the gum leaves.
Eucalyptus Leaves
Koalas are not poisonous to either their predators or to man. The Aborigines used to feast on koalas, as they were easy game. There is a mistaken belief that, because koalas feed on eucalyptus leaves, which are toxic, that this makes the koala poisonous if ingested. This is not correct. Some confusion may also derive from people mixing them up with the platypus, which has venomous spurs on its hind legs.
Koalas are herbivores. These animals spend most of their lives on trees eating leaves.
Eucalyptus leaves is the only food koalas eat. Although the leaves are poisonous to most animals, they have special bacteria that live in their stomachs to break down and digest them. Their diet includes up to one pound of leaves a day., HOPE IT HELPS :)
They spend a lot of time eating the leaves of Eucalyptus trees
The koala is a herbivore, eating eucalyptus leaves entirely.
ARE YOU CRAZY?!?! Nobody can eat a tree...but if you are talking about eating leaves, then be careful about what tree's leaves your eating,but most of the leaves shouldn't be unhealthy or poisonous, but this is my knowledge and thoughts.
