speech on judicious use of water
Answers
Of all the planet’s renewable resources water has a unique place. It is essential for sustaining all forms of life, food production, economic development andfor general well being. Water resources consists of both surface water and ground waterresources. The main source of all the water resources is the precipitation in the form of snowand rainfall. The surface water available in the form of canal water is tapped by constructingdam and reservoirs across the river at suitable locations. At some places surface water is alsotapped by constructing small harvesting dams across the choes. The seepage from the surfacecanal network, deep percolation of rainwater, return flow from surface irrigation form the part of ground water resources. The surface and ground water resources of the country playsa major role in agriculture, hydropower generation, livestock production, industrialactivities, forestry, fisheries, navigation, recreational activities, etc. In India 70 % of thewater resources are used for agriculture The table 1 shows the per capita per year availabilityand utilizable surface water in India. .The availability of water in India shows wide spatialand temporal variations. Hence the general situation of availability of per capita availabilityis much alarming. The map 1. shows the stage of ground water development in India. It isclear from the map that Punjab is one of the states where the ground water development is maximum.
WaterWater is a transparent fluid which forms the world's streams, lakes, oceans and rain, and isthe major constituent of the fluids of living things. As a chemical compound, awatermoleculecontains one oxygenand two hydrogen atomsthat are connected bycovalent bonds. Water is a liquidat standard ambient temperature and pressure, but it often co-existson Earthwith its solidstate, ice; and gaseousstate, steam(water vapor).Water covers 71% of the Earth's surface.[1] It is vital for all known forms of life. On Earth,96.5% of the planet's water is found in seas and oceans, 1.7% in groundwater, 1.7% in
Good morning to the excellencies, respected teachers and my dear colleagues. I would like to speech on a very important topic “save water” today at this special occasion. As well all know that how the water is important for the continuation of life on the earth. It is the most basic need of everyone (human being, animal, plant and other microorganisms). Water is the unique source of life, without water we cannot imagine the life here. Life on other planets is not possible just because of the absence of water. It is considered as the most important among other known celestial bodies. Almost three-fourth area of the earth is covered by the water and it constitutes around 60-70 % of the living world. It seems that water is endless renewable source on the earth because it is regenerated and redistributed all over the earth through evaporation and rain. It arises a question in our mind that if water is renewable source then why we should worry for water and try to conserve it.
Actually, there is only 1% of the water on the earth which is usable to us. And other water bodies have unusable water to us such as 97% salty sea water, 2% water in the form of glaciers and polar ice caps. Only 1% water is here for us over which a huge population all over the world is depended for the survival. Death is more possible in the lack of water than the lack of food. It again arises a question in our mind that why we are so late in realizing the need of water saving and conservation. Since the life of each and every living things on the earth depends on water, then scenario will get worse if useful water become dirty or started reducing. A water looking fresh and drinkable from outside can be mixed with the harmful and toxic elements through various sources like industries, factories, sewer, etc and cause illness and death if ingested by animals, plants or human beings. Here are some tips which really will help us to save water:
