Importance
Knowledge of surface ocean currents is essential in reducing costs of shipping, since traveling with them reduces fuel costs. In the sail-ship era knowledge was even more essential. A good example of this is the Agulhas current, which long prevented Portuguese sailors from reaching India. Even today, the round-the-world sailing competitors employ surface currents to their benefit. Ocean currents are also very important in the dispersal of many life forms. An example is the life-cycle of the European Eel.
Ocean currents are important in the study of marine debris, and vice versa. These currents also affect temperatures throughout the world. For example, the current that brings warm water up the north Atlantic to northwest Europe stops ice from forming by the shores, which would block ships from entering and exiting ports.

Famous quotes containing the word importance:
“A man’s personal defects will commonly have with the rest of the world precisely that importance which they have to himself. If he makes light of them, so will other men.”
—Ralph Waldo Emerson (1803–1882)
“In my public statements I have earnestly urged that there rested upon government many responsibilities which affect the moral and spiritual welfare of our people. The participation of women in elections has produced a keener realization of the importance of these questions and has contributed to higher national ideals. Moreover, it is through them that our national ideals are ingrained in our children.”
—Herbert Hoover (1874–1964)
“There is, I think, no point in the philosophy of progressive education which is sounder than its emphasis upon the importance of the participation of the learner in the formation of the purposes which direct his activities in the learning process, just as there is no defect in traditional education greater than its failure to secure the active cooperation of the pupil in construction of the purposes involved in his studying.”
—John Dewey (1859–1952)
