Is the Thai tradition of Buddhism on the decline?

Imagine a picture of Thailand and you might well come up with a scene of beautiful scenery and the Buddhist monks that are seen all over the country. Yet that might soon change. Numbers of those in the monkhood are a quarter of what they were twenty years ago; even those serving today don't know if they will continue in the long term. The decline is being blamed on modernity and materialism, with the Thai people increasingly turning away from traditional religious practises.
