Nowadays,people are faced with serious problems.One third of the world's people don't have enough clean water.I think water is the most important thing for human beings to live.I suggest we should save water and protect it from pollution.Not only the water,but also the air is polluted.More and more diseases are caused by polluted air.Itis really a big problem.I hope fatories would pay more attention to the air condition in future.And it is also everyone's responsibility to care for our environment.當(dāng)今人們面臨著嚴重的問題.世界上有三分之一的人沒有干凈的水.我認為水是人類賴以生存的最重要的條件.我建議大家節(jié)約用水,并防止水污染,不僅是水,空氣也被污染了.由空氣污染引起的疾病也越來越多.這的確是個大問題.我希望以后工廠要注意空氣質(zhì)量.關(guān)心環(huán)境問題,也是我們每個人的責(zé)任.
