World Water Day（WWD） began in 1993.It aims to protect freshwater resources!World Water Day is on March 22 every year.This year it focuses（聚焦） on groundwater.
    Groundwater is water in rocks，sands and gravel（礫石） that can hold water under our feet.Groundwater is a hidden treasure that enriches（使豐富） our lives.In the driest parts of the world，it may be the only water people have.
    Almost all of the fresh water in the world is groundwater，supporting drinking water supplies，farming，industry and ecosystems（生態(tài)系統(tǒng)）.Groundwater can help us to live and adapt（適應(yīng)） to climate change and also meet the needs of a growing population.
    However，in many places，human activities overuse and pollute groundwater.More water is abstracted（抽?。?from aquifers（含水層） than is recharged（補給） by rain and snow.We're starting to use more water than our planet can give us.Groundwater pollution is a special problem that can take（幾十年） or even centuries to recover（恢復(fù)） from.In other places，we simply do not know water is down there.
    We must use it sustainably（可持續(xù)地），balancing the needs of people and the planet.And we must protect groundwater from pollution.Let's start saving water now!
