Question

6．Four Wild Animal Species Were EndangeredMaybe you can still see them at the zoo．But that doesn't mean they're doing alright in the wild．
Tigers
All six tiger species are endangered，with Suatran tigers and South China tigers at a seriously endangered status．The main reasons for their population decline are illegal hunting and destroyed habitats，as humans clear forests to gather timber and build roadways．Only about 3890 tigers presently live in the wild．
Ground squirrels
That's right，even squirrels are endangered，specifically the San Joaquin ground squirrel．Native to California，USA，these guys have been disappearing since 1979 on account of the construction and human developments going through their habitat．Their total population is unknown，but it could be anywhere between 124000 and 4130000．
Giraffes
The International Union for the Conservation of Nature recently put giraffes at a vulnerable status，the level just before endangered．Th e giraffe population has declined 40 percent in the last 30 years，primarily due to loss of habitat and illegal hunting．Some giraffes are killed just for their tails，which are considered status symbols in Africa．
Asian elephants
The main threat to Asian elephants，one of the most intelligent animals，is their shrinking habitat．As the human population grows，people invade their land to build roads and railway tracks．Elephants in Myanmar are at an especially high risk for being captured and traded or used illegally in the tourist industry．Fewer than 50000 are left on the entire continent．
