Why Should We Save Our Sharks?

Sharks are top predators that play an important ecological role in marine ecosystems. Their health and wellbeing is therefore vital for maintaining healthy oceans — and by extension, vital for the communities that depend on the oceans for their food security and livelihoods.

Why do sharks need to be saved?

Why do we need to protect sharks? Sharks play a crucial role in healthy ocean ecosystems because they are a top predator—they keep prey species populations at a healthy level and prevent algae overgrowth that advances the decline of coral reefs.

Why people should stop killing sharks?

Most sharks serve as top predators at the pinnacle of the marine food pyramid, and so play a critical role in ocean ecosystems. Directly or indirectly they regulate the natural balance of these ecosystems, at all levels, and so are an integral part of them.

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.

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.

Should we protect sharks or humans?

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 does the world 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.

Why should sharks not be hunted?

The actual act of culling is often inhumane and cruel. Drumlines with baited hooks can ensnare sharks for days at a time before they eventually die, causing extreme suffering and distress. Even shooting the trapped animals does not always result in a quick and painless death.

Do sharks help the ocean?

Their “pit stops” along the way support ocean health: by eating in one location and pooping miles away in another, sharks help to cycle nutrients between ecosystems. When sharks dive, it also helps to mix nutrients across different ocean depths.

Should sharks be killed?

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 should we love sharks?

How do sharks benefit us?

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.

Can sharks ever be friendly?

New research reveals, that they do have a softer side, as they have been observed making friendships and patrolling in groups near Guadalupe Island. They form “social clubs” where they swim together for hours.

How do humans affect sharks?
