The Nature.
My very first poem, when I was in class 8 :) Trees, Rivers, Oceans and Seas, who provides us with all of these? These are things which may never cease, but trespassers destroy them with real ease. Spring blossoms, winter flakes, Save the earth for our sake. Reduce, re-use recycle now, Save the earth somehow. Snowy white winters that melted into springs, now are just some imaginary things. All this might not forever last, but let us at least preserve the present, if not the past.
