There is no doubt that we only have one Blue Planet.We must protect it.Blue Planet provides us food,water and life.But today,our planet becomes very bad .The atmosphere is not clear.More and more trees are being cut down.We are falling into danger.
We must control the speed of the population's growth .What's more,we had better not to cut down the trees.
We can't be sure whether our dreams will come true ,but we can at least be hopeful that our efforts to make the planet become more clear will be successful.It is obvious that our life will become happy ,too!
