It is maybe not much difference for them because mountains are like a water tanker that gives water sources.
Due to the effect of technology development, human had changed the surroundings of river to tourism center, hidroelectric generator, mineral quarried, and others. This may varied
the functions of river and progress mankind's level undirectly. Outcome of tourism at river and nearby it has established new oppurtunities of occupation besides given advantages to kingdom by getting exchanges of foreign notes when foreign tourists visiting our country.
Apart from these, the useful of hidroelectric generator enables to keep clean water sources to be used by Malaysians especially when the progress of occupants getting more obvious rather than having electric energy.

Water alley of St. Lawrence's big lake connecting to St. Lawrence's river with Ontario's lake to Erie's lake, Haron's lake, Michigan's lake and Superior's lake. Methods of transportation on water are carrying large quantity of things, connecting the Atlantic Ocean with large land, and the progress of of cities in Quebec, Montreal, Halifax, and St. John, hidroelectric generator, industrial sector and water sources. Unfortunately the alley around big lakes only functioning on May to November but this problem can be overcame by building canals and doors such as Welland's canal.
As conclusion, river is can gives us many benefits to human that must be taken care of to ensure the advantages can continued by many generations in the future.
