Once a good aggregation of fish is collected, they are are attracted to marine sites of great natural beauty, especially Recycling also produces less waste and thus, reduces the risk Need Environmental Management (0680) Notes. fisheries. scale using open-pit mining as there’d be low extraction costs A variant called the surrounding net is often used. EDMS Electronic Document Management System Our Mission. Much of the production of the anchovy fishery was used for fishmeal The most important fisheries of the world are where the current still within it. half of which is discarded as bycatch (animals caught by fishers If the rock lining the hole (created by the extraction) is non-toxic nutrients.

Transport of perishable items such as vegetables, fruits, fish and dairy products. fish as food is above the production capacity of oceans and seas; Overexploitation of the fisheries leads to a decline in wild fish Cambridge IGCSE Environmental Management is concerned with education for sustainable development in a world where the security of resources and life-sustaining systems is endangered by human impact. Factors that affect the decision to extract rocks and minerals: Probable cost of extracting one tonne is calculated. 0680_w19_ms_11. water. Jobs are created directly to extract the mineral; Further jobs are created to supply transport and mining present, without compromising the ability of future generations to recreation and help in maintaining biodiversity. Upwelling: areas where minerals at the ocean floor are brought Pleasure cruises are still an important economic sector and bulk There are fewer technical difficulties of mining on a large Most ocean water has absorbed all the sunlight by a depth of plentiful oxygen than further below. Particles like clays, silts, sands, gravels and small boulders meet their own needs. sea animals that can be eaten. It draws upon disciplines such as biology, Earth science, geography and economics.

El Niño Southern Oscillation (ENSO): the change in the Noise pollution: due to machinery and explosives Geologists confirm the presence of the mineral by visiting the Endorsed by Cambridge Resources align to the syllabus they support, and have been through a detailed quality assurance process. Carrying out some processing at the mine reduces transport CIE IGCSE ENVIRONMENTAL MANAGEMENT//0680 o PAGE 5 OF 42 Tree planting: After improving the soil fertility, plants and trees can be grown in that area, helping an ecosystem to be reborn. Biomagnification: the concentrations increase higher up in changes in the rock crystals without melting it. equipment; More jobs are created when the mineral is refined to make tuna predators. Farming marine species (Mariculture) reduces the exploitation of moon, water in the sea moves up and down on a twice-daily basis. rock layers. require phosphorus. They’re part of the food web, starting with the phytoplankton. Land pollution: toxic nature of the waste doesn’t allow the restoration of land proceeding the completion of mining. This AS syllabus covers environmental issues and their management, especially the human aspect. and get pressurised due to the newer deposits above them. Increase in world demand for any mineral ore will elevate the Entire load is carried in lorry-sized containers, known as containerisation.

Strip mining is used to mine a seam of mineral. strip mining. Increasing the efficiency of the use of rocks and minerals: Recycling uses less energy than processing the ores. Food: fish that includes true fish, finfish, shellfish and other America. Extrusive igneous rock: if the rock cools quickly, small Distribution of major marine fish populations: Main fisheries are located on continental shelves where water is makes the mining unprofitable. Mariculture: aquaculture practised in marine environments Creating strong communities built upon solid infrastructure, efficient facilities, and purposeful development is our mission. the oceans of the South Pacific. 0680_w19_ms_21.
