A água é um dos principais elementos da natureza. Sem ela, não poderia haver vida no planeta. Conhecer melhor suas características e funções ajuda a compreender sua importância e, principalmente em tempos de desperdício, a conservá-la para que nunca falte. Veja algumas informações sobre a água e descubra como é importante conservá-la.   Se todo o gelo das calotas polares derretesse, nos pólos norte e sul, ¼ &nbsp;da Terra ficaria alagada?
Segundo o Conselho Mundial de Água, 1,4 bilhão de pessoas sofrem com falta de água potável em todo o mundo?    E ... ¾ &nbsp;da superfície do planeta Terra é formado por água, mas apenas 2,7% pode ser consumida? A água potável do planeta está distribuída da seguinte maneira: 0,01% nos rios, 0,35%, nos lagos e nos pântanos e 2,34%, nos pólos (icebergs e geleiras). O Brasil tem 13,7% de toda a água doce do planeta. Destes, 80% está na Bacia Amazônica.  
Vamos economizar! Práticas do dia-a-dia podem desperdiçar muita água. Fique ligado nestas informações para evitar a perda desnecessária:  &nbsp;·&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Deixar a torneira aberta enquanto você escova os dentes pode gastar 80 litros.  ·&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Um banho de 15 minutos em chuveiro elétrico consome 144 litros.  ·&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Para regar o jardim com torneira aberta por 10 minutos, são gastos 186 litros.  ·&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Lavar o carro com torneira aberta durante 30 minutos consome 216 litros.  ·&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Lavar a calçada durante 15 minutos exige 280 litros.
