Why Are people taking care of koalas?

Answer 1

People are not "taking care" of koalas in the sense of keeping them as pets, because they are protected native animals, and may not be kept as pets.

However, various government and conservation groups are trying to preserve koala populations for the future, because they are at risk from a number of factors. The chief threat to the koala is habitat loss. Koalas inhabit prime land which man has decided is better used for housing developments. Not only do the koalas lose their sources of shelter and food, they are subject to dog attacks and being hit by cars as suburbia extends further outwards. A prime example of this is southeast Queensland, where koala numbers have dropped to 60% less than what they were a decade ago, entirely due to increased development.

Koalas are territorial, and they live in complex social communities where each member has a certain number of trees within its territory. When access to these trees is cut off by new roads, the koalas will still try to cross the road, and risk being hit. Relocation of koalas is rarely successful because their territorial and social habits are largely misunderstood. Another significant factor is predation by introduced species such as dogs and foxes.

Koalas are also subject to the disease chlamydia, which affects the koalas' fertility, and eventually leads to their death. Currently, there is no cure for this disease. At the best of times, the koala is a slow breeder, usually producing just one joey a year. Scientists are continuing to work on a cure, but so far there has been no success.
