Koalas are not in any immediate danger of extinction, nor are they officially endangered. There are, however, numerous factors which are proving to be threats to the koala.
Man is their biggest threat, causing loss of food source and habitat loss. Increasing urbanisation results in more koalas being killed by cars, unsupervised dogs, bushfires and even directly by cruel and irresponsible people. In particular, koalas have a range of home trees, and their territory is often split by roads through new urban developments. As a result, when koalas try to wander from one of their home range trees to another, they are hit by cars. Domestic dogs pose another major threat to koalas in suburban fringes.
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 - and where they now face extinction by 2020.
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.
To begin with, koalas are not extinct, nor even close to it.
Neither are they bears.
The koala bear is an animal that can sleep for 3 years but only will mate once. Koala bears are typically found in Australia.
First off, the question should be either "What math is used in Mechanical Engineering? or What is the highest level of math someone needs to take in order to become a Mechanical Engineer?" Most college programs require through Differential Equations to earn a BS degree in ME. This means you would need to take Calculus 1, 2, and 3, Linear Algebra, and Differential Equations once you get to college. It is assumed that most students going into engineering will have no less than Pre-Calculus before entering college while most will have taken Calculus. Now each college has different requirements for fulfilling the math requirements for an engineering program. I know from my experience, Georgia Tech teaches math differently than most colleges because they combine Calc 1-3 and Linear Algebra into just 3 courses instead of 4. My suggestion is look at the program requirements at the school you are interested in first. Second, evaluate whether you feel that you can learn the math. For those who struggle with math, if you really want to be an engineer, I suggest going to a smaller school where the class size will be smaller. This will have better student/teacher interaction so you can get more help.
Three toed sloths are not extinct.
Orangutans are disappearing because man is destroying their habitat. They are becoming extinct due to logging. They are also becoming extinct because of palm oil production, which uses the trees the orangutans need.

The word koala has thre syllables: ko / a / la
The Story of the Three Bears was created in 1837.
Do you mean the bears from Goldilocks and the Three Bears? They are Mama bear, Papa bear and Baby bear.
Goldilocks is the character who had an encounter with the three bears in the popular children's fairy tale "Goldilocks and the Three Bears."
the broad faced potoroo and the three toed potoroo are extinct
