求一篇题为pollution的英语演讲稿，3分钟就可以了，我是大二的学生，请写的详细一点，包括演讲稿开头的部分，

We can’t live without water,but now the water was polluted.It is the biggest problem.It influences our daily life.So we should find a way to solve this problem.Water is important resources.In our daily life,we often leave the tap on after cleaning hands.Sometimes we often drop litter in the river.So the water was polluted by us.I think we could use a bottle of water two or three times.We have to turn off the tap after cleaning hands.
Let’s try to form a good habit and save things around us.Let’s do it from now on!Fish can’t live without water.Plants can’t live without water.People can’t live without water,either.As you can see,the water is very important to us.But now drinking water is less and less.The water was polluted seriously.
So we would act quickly in order to save the water,But what must we do now?I think we can plant trees,clean the banks of the river,water the plants by using used water.Turn off the shower while we are washing hair.And we shouldn’t drop litter into the river and so on.
It’s our duty to try our best to protect and save water.And don’t forget that if we don’t save water,the last drop of water will be our tear.
