Impacts on Oceans Resources
overexploitation of ocean resources
dependance on the sea
Protesting against oil tankers entering bays.
Overexploitation or overfishing is the removal of marine living resources to levels that can not sustain viable populations. Ultimately, overexploitation can lead to resource depletion and put a number of threatened and endangered species at risk for extinction.
The exponential growth in human population experienced in last decades has lead to an overexploitation of marine living resources to meet growing demand for food
As the temperature increases threatens oceanic plants e.g. coral. The ocean is more acidic due to the amount of carbon dioxide being absorbed. This acidification harms marine life.
The ocean is a valuable natural resource which provides food, transportation, recreational activities and minerals. It regulates the Earth’s climate and plays a critical role in removing carbon from the atmosphere and producing oxygen.
Don't keep taps running when you don't need them. e.g. when brushing your teeth.
Have shorter showers.
Find out where your seafood comes from and its environmental conditions
Use chemical cleaning products which do not harm the environment and that are easily recycleable.
Buy Environmentally safe products;
Conservation of Water;
Walking or using public transportation (e.g. buses or trains) instead of using the car
Be considerate of the environment;
Don't feed animals or disturb their natural habitats. Do not litter near the water or anywere else. When fishing take your reels and other fishing gear with you.
All marine farms are licensed by the relevant State
authority. Licences include a number of conditions
(such as environmental standards) which must be met
during the operation of the enterprise. In Tasmania
and South Australia, licences are only granted within
areas already zoned for aquacultural production as
dictated by aquaculture zoning plans.
Management responsibility for aquaculture in Australia rests with the States. A number of States have aquaculture and coastal development plans in place. These are designed to take into account the needs of
both aquacultural developments and other user groups.
New South Wales – the NSW Fisheries manages aquaculture under the Fisheries Management (Aquaculture) Regulation 1995. Particular classes of aquaculture licences apply dependent upon the species cultivated

Over recent decades there has been a significant increase in the use of ocean resources. Competition for space and access to marine environments has led to the need of allocating ocean resources. There now is an increase in the range of values that society places on those resources and also a greater public awareness of the cultural and environmental significance of oceans. For example in December 1998 the Commonwealth government released Australia's Oceans Policy which set in place a framework for integrate and ecoysystems based on the planning and management for all of Australia's marine jurisdictions.

ocean resources and
Oceans cover almost three-fourths of the earth’s surface.
The fish that are caught are not always used for food. In fact, about 40% of fish are used for other purposes such as fishmeal to feed fish grown in captivity.
Nearly the whole of the ocean is polluted
