Birds have always been regarded as one of God's most magnificent and beautiful creations, and there are over 11,000 species of birds that have been recognized and described today. Scientists know more about birds than any other group of animals. The new report of the annual review of environmental resources has shown that more than 48 percent of bird species have seen populations decline globally. Birds are threatened by increasing human intervention, and birds that are large in size and take more time to breed, are facing the most danger. Birds are quite significant to the ecosystem, as they disperse seeds and eat insects.

With the shortening of the forests, the population of birds started decreasing sharply, and in the glare of modernity, we were confined to closed rooms. Greenery not only teaches humans but also animals and birds the way to live, but due to the increasing human population and the expansion of urbanization, the number of trees is continuously decreasing, causing trouble for the birds' survival.

The rate at which the biodiversity of the whole world is decreasing is quite pathetic, but it is not surprising at all. It is the result of the natural exploitation done by man for his selfishness that in the last forty years the number of animals and birds has come down to one-third. Birds are not only being sacrificed to human greed, but their numbers are also decreasing continuously due to climate change. Bird hunting and illegal trade continue by flouting laws. Birds are very sensitive to various chemicals and toxic substances and such substances can cause death by entering the body through the food or skin of birds.
