Human beings are spoiling the environmental balance.

Human beings are spoiling the environmental balance. I have visited kabootar khana or mehbub chowk where different varieties of birds are sold. Even I have bought some sparrows, crows and small birds with my money and set them free in the mother nature. The different varieties which we can find there are pigeons, sparrows, parrots, Eagles, owls and small multi colored birds. Birds have their freedom to fly in the sky. But we cruel human beings are capturing them in cages and selling them for our selfish needs to earn money. I don't know what the different government organizations and wild life protection organizations are doing for their concern.
