Reclamation at Jurong Island may affect natural sites

The reclamation area is very close to what seems to be two natural submerged reef: Terumbu Pidara and Terumbu Chawan, as well as a natural island called Pulau Buaya. Here's a view of Pulau Buaya from Google Earth. Looks like it has mangroves!
These natural sites obviously survived the massive reclamation to form Jurong Island. It's a pity that they are now being subjected to effects of reclamation nearby.

I have not visited these locations and do not know what is there and thus what we might have lost. This is why we need to visit as many shores as we can, while we can.
