You have seen nature very closely and described the beauty of nature in a very good way, as you have described about the perception of birds, that trees provide oxygen to humans. So the human being is happy because of his different activities, and indeed the human being who has been able to explain all things in a very good way. Could have described beautifully but you have seen all the beauty from the best point of view and well described your post is admirable.
