Lost of important green lung in Kuala Lumpur

If you go up to 86th floor Petronas Twin Tower, you will see this view. Before, people are talking about Bukit Nenas Forest Researve but now all turn into recreational area and buildings. No more forest in Kuala Lumpur to absorb carbon monoxide or carbon dioxide produced by vehicles and other human activities. If 5 millions people in Kuala Lumpur probably we need 10 millions trees to balance our healthy environment. Perhaps Kuala Lumpur need more islands of green.
