Population pressure on arable land contributes to the land degradation. The increasing population numbers and growing affluence have already resulted in rapid growth of energy production and consumption in India. The environmental effects like ground water and surface water contamination; air pollution and global warming are of growing concern owing to increasing consumption levels. The paper concludes with some policy reflections‚ the policy aimed at overall development should certainly include efforts

TRADE AREA ANALYSIS Trade Area Analysis‚ Development and Mapping Trade area analysis and mapping describe the characteristics of the area around a store or network of stores. Without accurate trade area definitions‚ you cannot measure the key statistics that impact a store’s performance. Use trade area analysis to aid site selection and target marketing. Trade area analysis and mapping tell you: • Where a store’s customers are coming from • How many customers you have in a trade area

Water Pollution – Essay Air and water are two most essential ingredients necessary for the existence of life. Air is unlimited. But there is limitation of fresh water‚ required for the human beings’ consumption. So‚ there is need to conserve water‚ by its judicious use and by protecting it from the pollutants. Our water resources are depleting very fast. We need to take action. It has been predicted that the future wars would be fought due to water problem. All around the world‚ countries

Surface Water - Surface water is water on the surface of the planet such as in a stream‚ river‚ lake‚ wetland‚ or ocean. It can be contrasted with groundwater and atmospheric water. - Non-saline surface water is replenished by precipitation and by recruitment from ground-water. It is lost through evaporation‚ seepage into the ground where it becomes ground-water‚ used by plants for transpiration‚ abstracted by mankind for agriculture‚ living‚ industry etc. or discharged to the sea where it becomes

Class: 4Sc1 Teacher: Pn XX Group Name: XX INTRODUCTION A water rocket is a type of model rocket using water as its reaction mass. The pressure vessel—the engine of the rocket—is usually a used plastic soft drink bottle. The water is forced out by a pressurized gas‚ typically compressed air. The term "aquajet" has been used in parts of Europe in place of the more common "water rocket" and in some places they are also referred to as "bottle rockets" (which can be
