Apart from poisoning the fish, this toxic fishing activity kills animals that are essential to the aquatic environment, such as corals, and provide food and shelter for a number of marine species. One square meter of coral reef is lost with every fish captured using this method. Also, overfishing has the potential to deplete main reef habitats and damage coral habitat. In many places, rapid human population growth, increased demand, the use of more advanced fishery technology, and insufficient maintenance and regulation have resulted in the extinction of key coral species and habitat damage.
When poisoning the fish other animals around in the aquatic envoiroment like for example corals, which porvide food and shelter for many species of underwater creatures. If this is not stopped coral reefs will become extint which is really bad not only for the species which feed and live there but also to the enviorment.
