Among the environmental problems, overfishing has become a serious concern, causing severe socio-economic and environmental impacts. Today, about billions of people depend on fish for their nutrition, and for many, it’s a lucrative source of income.
I’m a science geek. I’ll discuss talk about the perils of overfishing in the following section.
- Why is overfishing a menace?
Despite offering a means of living to billions of fishermen, overfishing continues to be a huge threat in recent times. Overfishing-related catastrophes are not entirely uncommon. The destruction of the Atlantic Canadian cod fishery in 1992 is a striking example of a calamity resulting from overfishing.
As pointed out by surveys, overfishing is major reason behind ecosystem destructions. The collapse of fisheries are responsible for destroying livelihoods for many fishermen. Furthermore, it poses serious threats to local food sources since several communities rely on fish as a source of nourishment.
- How does overfishing impact the food web?
Overfishing not only destroys economic structures but also threatens our ecosystem. For instance, sharks and tunas are frequent victims of overfishing. So when you alienate them from their natural habitat, creatures lying at the bottom of the water get adversely affected. Consequently, population may expand and behaviors deplete ocean ecosystems. Also, overfishing has proven to lower the growth of algae, causing serious environmental repercussions. Overfishing, in many ways, is responsible for depletion of coral reefs. Coral reefs are a significant component of the ocean ecosystem and, unfortunately, there is no way you can’t restore the condition once it’s damaged.
