Who is responsible???

Look at your surrounding
Full of dirt in it,
But you should keep in mind that
After all, you'll have to live in it.

You are the only one
Who has polluted it,
And you are the only one
Who says, "who has done it?"

You'll be glad to know that
Earth was full of life before 100 years,
But nobody cares to know that
What'll happen after another 100 years.

So get up and take the pledge now
That you'll take care of this planet,
Otherwise you'll be the first one
To leave this lovely living planet...
