Supreme court (sc) to hear plea seeking national heritage status for ram setu.

Why in news?

• Ram Setu, also known as Adam’s bridge, is a chain of limestone shoals between Pamban Island or Rameswaram Island, off the south-eastern coast of Tamil Nadu, and Mannar Island, off the north-western coast of Sri Lanka.
  • Recently, Tamil Nadu assembly also passed a resolution urging Centre to resume work on Sethusamudram Ship Canal project (SSCP).

• National heritage status is sought in the backdrop of SSCP that envisages dredging of a ship channel across the Palk Straits between India and Sri Lanka.
  • Two channels were suggested – one across Adam’s Bridge and another through Palk Bay.
  • SC, in 2007, had stayed the work for project and Centre was also willing to explore another route to SSCP without damaging Ram Setu.
• Significance of SSCP
  • Reduce steaming distances between east and west coasts of India.
  • Strengthen national security by improving navigation for Indian coast guards and naval ships.
• Concerns raised against SSCP
  • Would destroy natural barrier between Bay of Bengal and Palk Bay.
  • Oil and marine pollution associated with shipping traffic will aggravate ecological stress in region.
  • Adam’s bridge holds religious sentiments for the people.
  • Threats to coral reef platforms in Gulf of Mannar.
