In March, a group of protesters marched to Chatuchak District Office to show their anger at the cutting down of trees at Bon Marche Market. At the same time, TV presenter Chorpaka Viriyanond called on Bangkokians to band together to save urban trees. Since then, the Big Trees activist group has joined with some 65 organizations to form the Thailand Urban Tree Network (goo.gl/3UZH9s). BK chats with two of their team, Chanadda Damngern, 23, of Urban Tree Care (goo.gl/Kbsj8L), and Oraya Sutabutr, 47, of Big Trees, on how everyone can help make Bangkok greener.
