Wetlands are essential to maintain the balance of the hydrologic cycle; they offer large surface areas of water and thus regulate the amount of water that flows, evaporates and eventually falls down again as rain. In addition, a wetland such as an estuary is the boundary between the sea and the land; they can buffer the influence of the tides and sea currents, and are usually very productive areas (that is, if pollution does not degrade them).\nEspecifically for the San Francisco area, here´s a link to the site for the San Francisco Bay reserve, they discuss the benefits and problems of the area:\nhttp://nerrs.noaa.gov/SanFrancisco/welcome.html\n\nand the local Wetlands Regional Monitoring Program:\nhttp://www.wrmp.org/\n\nand

Job One:  Secure the borders.  Without that, there's not much point in screwing around with anything else...might as well be rearranging deck chairs on the Titanic...

water, drinkable water. territorial access to ports and water. \n\none day certain water may get so contiminated the ecosystem will not be able to purify the water. then ground water will become very valuable.

Wetlands filter water that is headed to the ocean. Therefore, less pollutants in the oceans and more stink in the wetlands.

The two major sea ports in Vietnam are Hai Phoung and Saigon (Ho Chi Minh City). There are numerous smaller ports especially along the river tributaries of the Red River and Mekong Delta.

The Coast Guard does not 'run the ports' in a business sense.  They patrol and provide security, which our taxes do pay for.

to maximize surface area for the collection of sunlight and minimize weight and material used. also, yes it helps transport water and nutrients.

Applications of trigonometry\nMarine sextants like this are used to measure the angle of the sun or stars with respect to the horizon. Using trigonometry and an accurate clock, the position of the ship can then be determined from several such measurements.\nEnlarge\nMarine sextants like this are used to measure the angle of the sun or stars with respect to the horizon. Using trigonometry and an accurate clock, the position of the ship can then be determined from several such measurements.\n\nThere are an enormous number of applications of trigonometry and trigonometric functions. For instance, the technique of triangulation is used in astronomy to measure the distance to nearby stars, in geography to measure distances between landmarks, and in satellite navigation systems. The sine and cosine functions are fundamental to the theory of periodic functions such as those that describe sound and light waves.\n\nFields which make use of trigonometry or trigonometric functions include astronomy (especially, for locating the apparent positions of celestial objects, in which spherical trigonometry is essential) and hence navigation (on the oceans, in aircraft, and in space), music theory, acoustics, optics, analysis of financial markets, electronics, probability theory, statistics, biology, medical imaging (CAT scans and ultrasound), pharmacy, chemistry, number theory (and hence cryptology), seismology, meteorology, oceanography, many physical sciences, land surveying and geodesy, architecture, phonetics, economics, electrical engineering, mechanical engineering, civil engineering, computer graphics, cartography, crystallography and game development.

Tide refers to the water level present in the ocean. It increases depending upon the season such as winter, summer and tropical. These tides levels are categorically watched by meterological dept inorder to protect the seashore areas in lieu of natural calmities such as tsunammi, typhoons etc.\n\nIn terms of shipping, tides are always watched by the captain inorder to move the ship safely saling to avoid grounding in mud.
