This current is the West Wind Drift.

B. The Atlantic Ocean Currents

The North Atlantic westerly winds move the water eastward as the North Atlantic Current, or North Atlantic Drift. The northeast trade winds push the water to the west, forming the North Equatorial Current. The north-south continuity currents are the Gulf Stream, flowing northward along the coast of North America, and the Canary Current, moving to the south on the eastern side of the North Atlantic.

C. The Indian Ocean Currents

The Indian Ocean is mainly a Southern Hemisphere ocean. The southeast trade winds push the water to the west, creating the South Equatorial Current. The Southern Hemisphere westernizes still move the water eastward in the West Wind Drift. The West Australia Current moving northward completes the gyre and the Agulhas Current moving southward along the coast of Africa.

D. The Arctic Ocean Currents

The Norwegian Current supplies the Arctic Ocean from the North Atlantic; some of this flow enters west of Spits Bergen, but most flows over the top of Norway and Finland and moves eastward along the Siberian coast into the Chukchi Sea.

Outflow from Siberian Rivers is caught in the eastward flow of water and ice along Siberia. Eventually this discharge joins the gyre distributing sediments and pollutants throughout the Arctic.

El Nino syndrome

The world continues to be pounded by abnormal weather, due to man's indifference towards lesser mortals. The warnings of the atmosphere that is normally referred to as the "Green House Effect," is caused by the steady build up of six green house gases, emitted by the burning of petroleum by motor vehicles and coal in power plants. It is estimated that about 20 to 30 billion tons of carbon dioxide are discharged to the air each year, and that there is 30% more carbon dioxide in the air today than in 1860. Under these conditions, it is likely that the earth will heat up by a further degree within the next 20 years.

The lifestyles of the more wealthy nations, built up with the aid of science and technology with in-built self-destructive features, are openly criticized today. The high rates of consumption and pollution of the limited resources of the earth by the rich stock, makes it impossible for others who are not as fortunate, to live comfortably. This form of life could be challenged on grounds of natural impartiality. To bring a more equitable distribution of resources the rich must live more simply so that the poor may simply live.

The message on conservation that is already conveyed is very clear. The basic task for all to follow is to reduce as rapidly as possible, the impact of civilizations on the earth's life support combinations. To achieve these objectives, the world must reduce population, reduce consumption and change scientific technologies to eliminate or reduce the eviction of toxic gases into the atmosphere.
