Water conservation encompasses the policies, strategies and activities made to manage fresh water as a sustainable resource, to protect the water environment, and to meet current and future human demand. Population, household size, and growth and affluence all affect how much water is used. Factors such as climate change will increase pressures on natural water resources especially in manufacturing and agricultural irrigation. The goals of water conservation efforts include: * Ensuring availability of water for future generations. This requires that the withdrawal of fresh water from an ecosystem does not exceed its natural replacement rate. * Energy conservation. Water pumping, delivery and waste water treatment facilities consume a significant amount of energy. In some regions of the world over 15% of total electricity consumption is devoted to water management. * Habitat conservation. Minimizing human water use helps to preserve fresh fire habitats for local wildlife and migrating waterfowl, as well as reduces the need to build new dams and other water diversion infrastructures. ==Strategies== In implementing water conservation principles, there are a number of key activities that may be beneficial. #Any beneficial reduction in water loss, use and waste of resources. #Avoiding any damage to water quality. #Improving water management practices that reduce or enhance the beneficial use of water. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Water conservation」の詳細全文を読む スポンサード リンク
