The short answer is yes. Sharks are important for a variety of reasons, many of which have to do with policing the ecosystems in which they live. A number of shark species are “apex predators,” which means they’re at the top of the food chain and have no natural predators of their own.
Why sharks should not be protected?
Sharks are a vital part of our ocean environment. They act as apex or top predators, maintaining the balance of all life beneath them.
What will happen if we keep killing sharks?
If we wipe out the big sharks, so the theory goes, we get a boom in the population of the animals they eat — mesopredators like smaller sharks and seals. Those mesopredators in turn deplete their prey, and on it goes down the food chain.
Are sharks important to humans?
Sharks keep the food web in check.
These sharks keep populations of their prey in check, weeding out the weak and sick animals to keep the overall population healthy. Their disappearance can set off a chain reaction throughout the ocean — and even impact people on shore.
Are sharks a threat to humans?
Most sharks are not dangerous to humans — people are not part of their natural diet. Despite their scary reputation, sharks rarely ever attack humans and would much rather feed on fish and marine mammals. Only about a dozen of the more than 300 species of sharks have been involved in attacks on humans.
How can we protect sharks from humans?

Why should we protect sharks for kids?
Alongside other predators, sharks play important roles in helping to maintain the delicately balanced ecosystems that keep our oceans healthy. Their feeding can affect prey population numbers, but also prey distribution as they select a habitat to avoid being eaten.
Do we need sharks to survive?
Sharks keep ocean ecosystems in balance
Sharks limit the abundance of their prey, which then affects the prey of those animals, and so on throughout the food web. Because sharks directly or indirectly affect all levels of the food web, they help to maintain structure in healthy ocean ecosystems.
Will killing sharks save lives?
The available scientific evidence does not convincingly support the claim that killing sharks will reduce the risk to public safety. The RSPCA only accepts the management of wild animals where it is justified, effective and humane; the killing of sharks does not meet these criteria.
Why are humans killing sharks?
The overfishing of sharks is driven by international trade that goes way beyond their fins. In recent years the shark meat trade has rapidly expanded and shark products such as cartilage and oil all contribute to a market worth almost $ 1 billion per year.
Would humans exist without sharks?
“It would be a gigantic failure for humanity that would affect everything from coral reefs to food security and climate change. Once sharks are gone, there is nothing we can do to replace the critical role they play in the balance of the oceans.”
Why can’t humans survive without sharks?
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.
Why should we love sharks?
We Need Sharks. Besides amazing us with their variety, size, and beauty, it is increasingly clear that sharks can be important in combatting many human diseases. For example, the tooth-shaped scales of a shark’s skin are designed to help the animal move swiftly and easily through the water.
Are humans the biggest threat to sharks?
The biggest threat to sharks globally is overfishing. Each year many tens of millions of sharks are landed.
Do sharks eat humans or just bite?
Attacks are extremely rare and people are rarely consumed by sharks. A shark is capable of eating someone if they wanted to but it often doesn’t, which suggests we’re not considered prey and certainly not targeted, so that should allay a lot of fears.
Do sharks mistake humans for seals?
The apex predators take a bite out of swimmers because they resemble seals and sea lions—especially when they’re on a surfboard. New video footage suggests this may indeed be the case. Great whites and other sharks hunt from below, relying on the contrast of their prey backlit by the light above.
Why do we need sharks?
As apex predators, sharks play an important role in the ecosystem by maintaining the species below them in the food chain and serving as an indicator for ocean health. They help remove the weak and the sick as well as keeping the balance with competitors helping to ensure species diversity.
Are sharks attracted to period blood?
A shark’s sense of smell is powerful – it allows them to find prey from hundreds of yards away. Menstrual blood in the water could be detected by a shark, just like any urine or other bodily fluids. However, there is no positive evidence that menstruation is a factor in shark bites.
How many sharks are killed each year by humans?
100 million sharks
How Many Sharks Are Killed Every Year? An estimated 100 million sharks are killed per year throughout the world, a startlingly high number and one that is greater than the recovery rate of these populations.
Should we care about sharks?
Without sharks, entire ecosystems will collapse
Sharks are apex predators. Being on top of the food chain means sharks play a vital role in maintaining the health of marine ecosystems. If sharks are removed from oceans, an imbalance in biodiversity — known as a top-down trophic cascade — can occur.
How does killing sharks contribute to climate change?
Plummeting shark numbers means more sea turtles around to deplete the seagrasses which, once destroyed, release their blue carbon stores and contribute to global warming. A shark’s body is another source of blue carbon—the carbon captured by the world’s ocean and coastal ecosystems.
