Workers carry a rope line to fasten a decommissioned ship at the Alang shipyard in the western Indian state of Gujarat, March 27, 2015. The European Union plans to impose strict new rules on how companies scrap old tankers and cruise liners, run aground and dismantled on beaches in South Asia. However the practice in India, Bangladesh and Pakistan, hazardous for humans and the environment, will still be hard to stop. European, Turkish and Chinese recyclers are set to benefit from the revamped standards. Depending on raw material prices, ship owners can make up to $500 per tonne of steel from an Indian yard, compared with $300 in China and just $150 in Europe. (Photo by Amit Dave/Reuters)
