Okay so I want you to write a essay for me about Asiatic black bear

Asiatic black bears are found in the forests of Eastern Asia from Afghanistan to Taiwan and Japan, particularly in hilly and mountainous terrain. Bears hibernate at the northern extent of their range but further south migrate to warmer areas in winter. Nocturnal when in the vicinity of humans they appear naturally diurnal spending about half their time in trees, often on a platform made from branches and vegetation. The bear has a reputation of being extremely aggressive towards humans. Of medium size, Asiatic black bear have long, usually black but sometimes brown, fur and a distinct yellow, cream coloured or white chest patch which is often crescent-shaped. Hence the alternate name of “moon bear”. Length is around 120 centimetres to 2 metres with males weighing about 60 to 200 kilograms and females about 40 to 140 kilograms. The bears are omnivorous although predominately herbivorous. Except for females with cubs they are solitary. Mating occurs in June and July with litters of from one to four cubs being born in January and February in a winter den. Cubs remain with their mother for a year to eighteen months. Asiatic black bears are classed as vulnerable to extinction with a decreasing population. Longevity in the wild is unknown but is probably between 20 and 25 years and can be up to 30 years in zoos.
