In 1972, a corporation deposited a patent for the use of the By natural means blue blood of horseshoe crabs for immunological testing60. Limulus amebocyte lysate is a substance found in the crab’s blood that reacts with endotoxins, making it handy for detecting contaminants or destructive compounds in medicine. It is also broadly used in vaccine testing61. Due to this fact, all over 50 % 1,000,000 horseshoe crabs are caught and bled in the pharmaceutical industry each year, a course of action which might be demanding and lethal with the crabs, and it has therefore been called both unsustainable and unethical62. The moral, sustainability and human health implications of the scenario deliver an example of how competing values might make final decision-earning complicated.
