More than 200 environmental protection activists urged the Changhua County Government yesterday not to obstruct the designation of a belt of intertidal zone along the county’s west coast as a wetland of international importance.

The environmentalists from several civic groups made the call in a protest in front of Changhua County Hall against a NT$400 billion (US$13.76 billion) investment project to build a major petrochemical complex on land close to the estuary of the Jhuoshuei River (濁水溪).
