For Mains


  • Recently hundreds of Olive Ridley turtles have washed ashore along the coastline between Kakinada and Antarvedi in the Godavari region of Andhra Pradesh.
  • The effluents being released from the aqua ponds along the coastline and the discharges from the pipelines of the onshore oil exploration facilities are seen as the causes for this.
