Why are chinchillas going extinct?

Chinchillas became endangered when the fur trade began between Europe and the Americas. Trappers, the men who trapped the animals for the fur trade, would kill the chinchillas and sell the pelts to Europe to make the high demand for chinchilla fur. Pretty soon, the chinchillas were not easily found anymore because they were hunted close to extinction. Chinchilla hunting was then outlawed after chinchillas became endangered and some species extinct.
