About 25 percent of shark species are currently endangered. Taking the fins from sharks for soup is a despicable trade, but thankfully educating consumers about the damaging practice is working, and quite well. Analysts have reported that the demand for shark fin soup has fallen about 25 percent in the last decade, and around 50 to 70 percent in recent years. What’s the best way to help endangered sharks in need? Never order or eat shark fin soup, without a demand there is no need for a supply.
