Fish Going Extinct

Too many fish species are in danger of going extinct shortly. Years of overfishing, pollution, and harmful human activity brought us to this point.

What happens if fish go extinct? Fish extinction would cause changes in the weather, disruption of aquatic ecosystems, poverty, hunger, economic losses, and overall chaos. It would lead to significant repercussions, affecting marine life and all forms of life, including humans.

This article will help you understand just how serious a problem this is. I will discuss exactly what will occur if all fish go extinct. Unfortunately, it can happen in the next decade. Aside from this, I will also talk about what needs to happen to turn the situation around.

Consequences Of Fish Extinction

It may not seem like a big deal at first, but if fish go extinct, we will also suffer. If all fish species disappear, this will affect the environment, the economy, and health.

These are explained in more detail below:

The Collapse Of Aquatic Ecosystems

Oceans are ecosystems, and every living and nonliving being is equally important in maintaining equilibrium. Losing all fish would disrupt the entire food chain as some animals feed solely on fish and seafood.

The land animals who eat them would then also lose a food source. As more animals starve, this will continue until it affects everyone at the top of the chain, including humans.

Rampant Pollution

Marine creatures control pollution in our waters, but it is becoming increasingly difficult to do. Fish and aquatic animals help filter toxins and harmful chemicals in the ocean.

They can no longer do this once they are extinct. It will lead to even more pollution in our water, air, and land.

The air quality will decrease as plenty of aquatic plants are equally responsible for making up the oxygen we breathe. With fewer plants performing photosynthesis, we will also have less oxygen.

Changes In The Weather

The Earth’s water cycle relies not only on bodies of water but also on aquatic creatures. Without sea animals like fish, oceans will become dirty and toxic. As a result, rainfall might be affected.

We could experience acid rain that will kill even more animals and plants in the water and on land.

Loss Of Livelihoods

In many countries, fishing is a large industry that powers their economies. For instance, fishing is one of the main livelihoods in Japan, Thailand, Indonesia, and the Philippines.

Once fish disappears from the oceans, so will the jobs of millions of workers in this industry. That includes anglers, boat captains, factory and canning workers, market vendors, and corporate employees.

The loss of seafood would lead to an economic collapse across the globe.

Mass Food Shortages

Fish extinction will be devastating for many populations who consume seafood. People who cannot afford poultry or meat rely on fish for their everyday sustenance.

Some are also allergic to other foods and can only eat fish. Other people are pescatarians and do not eat meat by choice.

If this becomes a reality in 2050, many people will go hungry. It may result in widespread famine, malnutrition, poverty. We might also see a decline in health and a rise in different illnesses.

The Collapse Of Civilization

I know this sounds extreme. However, considering all of the possible effects of fish extinction, this is not too far off. Civilization is surprisingly fragile, and the more we destroy the planet, the more we hinder our progress.

Moving Forward

Our current practices are not sustainable at all. Something needs to change to save our oceans, marine life, and human life.

Fishing Quotas And Regulations

There are already some regulations in place. The problem is that they are not being enforced enough or not even enforced in the first place. These rules only exist on paper to disguise that government authorities are not taking action.

These laws should be strictly implemented, and fishing companies must be monitored.

Aside from the existing regulations, we also need updated ones. Since these were approved, the situation has changed, and we need to be more aggressive in combating fish extinction.

It can be accomplished by imposing quotas on the number of fishing vessels allowed to operate. Commercial fishers should also have a quota on the number of fish they catch and what species they can catch.


Aquaculture refers to fish farming or raising fish in captivity. Many wild fish species are endangered, so aquaculture can be a temporary sustainable alternative. Farming fish instead of catching fish in the wild may allow ecosystems to replenish for the time being.

It would also provide more affordable food sources. It is cheaper to farm fish than to capture them in the wild. So, fisherfolk can sell them for much lower prices.

Marine Reserves

Aquatic ecosystems must be protected at all costs to prevent further damage, especially the most vulnerable ones. To do this, we can set up marine reserves or protected areas.

In these reserves, the catching of fish will be strictly prohibited. It has to be done for the ecosystem to heal and return to its original state.

Increase Biodiversity

To have a healthy and balanced ecosystem, there should be enough biodiversity. Authorities can start programs with this goal in mind. If areas have experienced species extinction or endangerment, they could benefit from this program.

Nondestructive Fishing Methods

Since we will continue to eat seafood, the least we can do is employ safe fishing methods. Blast fishing and cyanide fishing are already illegal, but some still use them.

There needs to be a crackdown on these fishing companies. It aligns with the first proposed solution, which is to have better regulations.


Fish going extinct will have devastating effects on humanity, and it could happen sooner than we think. That is why we need to act as early as now. It is in our best interest to protect marine life and reverse the damage we have caused.
