Better be quick.
Sri Lankans are catching up with westerners and Asia (China). Industrial development comes with a great damage to environment. People living in Sri Lanka do not have any appreciation for what they got. They are so taken by Western values and chasing material possessions. Very soon they will start clearing forests and will start building concrete jungles. I remember our village monk (he disrobe later) burn the whole forest and plant banana trees. Now the land is neglected. The forest did not recover even after fifty years. Some of the trees burnt were more than hundred years old. I was young, I just cried in my heart because they destroy the forest we use to play!
Only the westerners can stop this destruction. Because many of the people in third world countries are ignorant!
PS: If you go to Sri Lanka and go to Kandy, Please go to Udavatta Kale to see the sample of saved ancient forest. (walking distance from the town or just 2 dollars for the taxi)
There are some forest monks living there as well.
