Could wind farm installation deafen marine life?

Wind farms may be a vital source of green energy, but new research shows that the construction of off-shore wind farms could potentially be damaging the hearing of harbour seals and other marine life. Researchers at St. Andrews University in Scotland believe that there is cause for concern that human building operations in our coastal waters, for example the pile driving process that hammers the foundation posts for wind turbines into the sea bed, could be damaging the hearing of marine mammals to an extent we hadn’t previously guessed at.
