I remember the days with the trees at the sides of road at the Kathmandu Valley. The green lands at the mid of the city replaced by concrete structures. 
Even the small green covers while seen from the place high above in the kathmandu gives us happiness that there has still been some greenery around kathmandu.
Greener and Managed Kathmandu was the theme that was carried by the mayor Bidhya Sundar Shakya of UML but to our great shock, it was just the election slogan.
If I have to relate I would point out the following causes which should be taken seriously by concerned :
1. Politics for Politics not for Profession.
2. Accountability and transparent Credibility of bureaucrats. The service promotions and other facilities should be effected by the things the bureaucrats gives to the society.
3. People should be atleast bound by the strict laws and the laws implementing body should also be strict.
And lots of similar other things should be carried out. But as you said who cares.
