What is the main reason for killing sharks?
Overfishing. Overfishing is the biggest threat to sharks: more than 100 million shark are killed every year, with a large number of them being caught for their fins. But some scientists say that the finning trade means the general issue of overfishing is often overlooked.

How many sharks are killed daily?

What happens if sharks go extinct?
If you’re not a big fan of sharks, this might seem like a good thing, but the absence of sharks would be devastating to ocean life. Sharks are an essential, keystone species that help balance other animals in the ocean’s food web, and without them, many, many other species would die.
Can a shark survive without its fin?
Without their fins, sharks can not swim and suffer from significant blood loss. They ultimately starve to death or are slowly eaten by other fish. Most drown because sharks need to keep moving to force water through their gills for oxygen.
Why are so many sharks killed each year?

How fast are sharks going extinct?
The number of sharks found in the open oceans has plunged by 71% over half a century, mainly due to over-fishing, according to a new study. Three-quarters of the species studied are now threated with extinction.
Should we stop killing sharks?
Despite often being tarred with the same brush, most species of shark grow to a relatively small size, feed on fish, crustaceans or other small aquatic animals, and pose absolutely no threat to human life. On the contrary, we need them to keep the marine ecosystems that we rely on for food and recreation healthy.
