Threats to Sharks - Humans
One of the largest threats that sharks face in the 21st century is finning. Finning is the inhumane practice of hacking off the shark's fins and throwing its still living body back into the sea. The sharks will either bleed to death or drown. Shark fins are in high demand due to the popularity of the Asian delicacy, shark fin soup. Estimates of sharks killed (mostly for their fins) range from 63 to 273 million per year.
