Solutions to the problem

Two solutions to this problem are better fishing practices, and establishing marine protected areas, or MPA's.

Solution 1: Better fishing practices

By implementing better fishing practices such as limiting catches, banning cyanide fishing or blast fishing, and reducing overfishing pressure on coral reef ecosystems. They should also protect herbivorous species to control algae growth.

Overfishing

sdecaire — 2024-09-18 05:23:56 UTC

Overfishing is catching too many fish and depleting the amount of fish in a certain area. It negatively impacts marine life and usually unwanted fish and sea creatures are discarded after the fact.

Evidence 1

Overfishing depletes certain fish like surgeonfish and parrotfish, which are helpful in controlling algae growth on coral reefs. It makes it hard for the coral reef to regenerate. Studies show that overfishing led to an increase in algae cover and a decrease in coral cover.

Location of the issue

Studies show that the problem is mainly in the Caribbean and the Indo-pacific ocean. They say that over 95% of coral reefs are under threat, especially in Southeast Asia.

Its effect

Coral reefs are home to 25% of all marine life. Overfishing contributes to algae overgrowth and less diversity of species. Sea creatures and organisms that rely on coral are forced to migrate elsewhere, or die off. This can lead to species extinctions and less marine biodiversity. As the reefs deteriorate, they provide less services like protection, shelter, and nutrients. This can lead to coastal erosion, which is dangerous for marine life.

Solution 2: Establishing MPA's

MPA's should be placed in certain zones where coral reefs are balanced and healthy. By giving coral reefs a chance to regenerate, it can restore biodiversity and healthier coral structures.

How it is impacting coral reefs

sdecaire — 2024-09-18 05:23:56 UTC

Overfishing effects coral reefs by disrupting marine life and the balance of marine ecosystems. It minimizes the strength of coral reefs and makes them more susceptible to other factors like climate change and pollution.

Algae overgrowth

Evidence 2

When people overfish, they tend to look for predator species. Without predators in marine life, an overabundance of smaller fish occurs, and smaller fish feed on essential organisms that corals need.
