Endangered
Sperm whales have been hunted for years due to their blubber. This blubber can be used to create candles, soap, machine oil, and more. In the 19th and 20th centuries, nearly one million whales were killed so in 1980 there was a law against this. Thus, ambergris is so rare these days.
Very Rare
Not only is ambergris so rare but the process of creating it is also very slow. Most people also think that not all sperm whales produce the substance. Expert officials even say that only 1% of the population produces this. It is usually found in the Atlantic Ocean.
