Why Have We Turned Cruel

Why have we turned cruel on nature? With total indifferent attitude and harmful for future It is finding disfavor with natural lovers They try and canvass support from nature supporters What nature has failed to afford us? Not enough of wood to build houses! Or fire wood to poor and nice shelter for them Fruits in abundance for everybody to cater I watch the birds to go away or migrate From civil population to isolated places Their presence is dwindling anyway Make the nests far away places and stay Sparrows have completely disappeared Previously we used to find them in houses when appeared In kitchen or in drawing room with lovely sound Now they are no where seen even if make round Such a heavy toll for beautiful birds Cuckoos voice too rarely heard Crows and squirrels have become extinct Streets now smell heavily and stink The crows were excellent service provider The food left over were picked as if at placement of an order They may come and finish quickly their job Now we are at pain to notice their absence on top of the house Nature and birds definitely cater our needs Now they have deserted us on count of our greed We have destroyed their hide outs They are forced to opt out or quit
