Chemical treatment of the waste and biological treatment o What is AS/NZS ISO 14001:2004? Physical damage can be caused to seabed and associated habitats coral reefs. Chemicals and building materials: many materials in the oceans have been eroded from the land, where rain and wind break down rocks, and are carried into the oceans via rivers. with photosynthesis; they also act as a source of heavy metals Improvements in the performance of the machines used in mining of job and reduction in food supply; Size of fish gets progressively smaller, increasing demand for food; Harvest of untargeted/protected/endangered marine species that are As their populations grow, they create habitats for many species. minerals. Reduces the number of fish that grow to maturity and rocks, and are carried into the oceans via rivers. Thus, fish are found where there are plentiful phytoplankton.
