Over-fishing too much for the ReefOver- aggressive fishing hasn’t been much of a problem for The Great BarrierReef until the past few decades. The Great Barrier Reef, a highly popular tourist destinationoff the coast of Australia, has a very delicate ecosystem. Over- fishing of certain speciesand aggressive fishing is destroying the reef. Organisms in a coral reef are very dependenton each other, so one species with too may or too little population size will completelythrow off the ecosystem. The aggressive fishing by many is causing disruption in the coralreef food chain and affecting many different species.The Great Barrier Reef is home tomany organisms. With fishermenconstantly moving their boats overthe reef, it can get badly damaged.
Human Impact• Humans are using aggressive fishing methods and causing the coral reefs tobreak.• The coral reef food chain is also being affected by aggressive fishing. Agrouper fish, very popular food to eat, is being overfished. This is leading toan increase in damselfish. Damselfish help create pockets in coral reefs wherealgae grows and damselfish feast. If their natural predators are decreasing,then algae can take over the coral reef, killing it.• Over-fishing will also disrupt the marine ecology of the Great Barrier Reefbecause of the special nutrients, salt, and oxygen contents provided by thefish.• Ships sailing over the Great Barrier Reef need to do so more cautiously due tothe damage caused to the reef. “The Shen Neng 1 hit a sandbank at full speedcausing extensive damage,” reports BBC News. Humans not being careful andconscious while maneuvering over the Great Barrier Reef can lead to negativeconsequences.
