Sika deer lupus hodophilax"), over a century ago. Without its main enemy, the population of sika exploded and it is now overpopulated in many areas, posing a threat to both forests and farmlands. Efforts are now being made to control its population instead of conserving it. None of its subspecies is endangered except the Kerama deer ("C. n. keramae") in the tiny Kerama Islands. In 2015, Japanese Ministry of the Environment estimated the population at 3,080,000 in Japan, including Hokkaido. China used to have the largest population of sika, but thousands of years of hunting and habitat loss have reduced the population
Animal cracker Animal cracker An animal cracker is a particular type of small cracker/cookie, baked in the shape of an animal, usually an animal either at a zoo or circus, such as an African lion, tiger, bear or elephant. The most common variety is light-colored and slightly sweet, but darker chocolate-flavored and colorful frosted varieties are also sold. Although animal crackers are made with a layered dough like crackers, they tend to be sweet in flavor, but still technically a cracker and not a cookie. Other animal-shaped crackers and cookies are popular, such as Teddy Grahams, Goldfish, Hello Panda and Koala's March.
