Document Summary
Ocean provides a range of goods and services to human life and activities. Marine pollution: introduction by man, of substances or energy into the marine environment resulting in deleterious effects such as farm to living resources, hazards to human health, and hindrance of marine activities. Climate change: a change of climate that is attributed to human activity, altering the. Physical resources result from deposition, precipitation or accumulation of useful composition of the global atmosphere substances in the ocean. Hydrocarbon deposits: petroleum, natural gas, methane hydrate. Mineral deposits: sand and gravel, magnesium and its compounds, manganese nodules, salt, etc. Petroleum products are produced from processing of crude oil. Oil and natural gas are often found in marine sediments. Both oil and natural gas originate from sinking organic matter. Freshwater is extracted from seawater by desalination. Biological resources: living animals and plants collected for human use and animal feed. Fish, crustaceans, and molluscs are one of the most valuable living marine resources.
