This morning, when I was walking by a small trail around Ramkot, the nearby small village of Sitapaila area of Kathmandu valley, I stumbled through many instances of open spaces being engulfed by expanding urbanization.
Needless to say, the heavy influx of people from the other district has pushed this capital city of Nepal towards its limit. In fact, the city is currently going through the border of its carrying capacity. 
Moreover, the conglomeration of most of the administrative centers, that include ministries, departments, as well as other facilities, such as the international airport, bigger hospitals, and offices of most of the corporations in this valley is another reason why people have to travel to this city. 
Further, some newer middle class also head their way towards this city to get a better education for their children and a discent life for them.
However, the influx of the better income group towards the big towns--including Kathmandu, comes with a price. Meaning, there is demand for land to build their houses. 
As a result, slowly, day by day, the remaining space around the cities are turned into concrete jungles.
Along with this rapid expansion of the housing facilities, there is also a speedy deterioration of the natural habitat of the plants as well as of animals residing in the city. This is probably the worst nightmare of any budding city in the world.
