Hundreds of monumental human shaped statues are motionless, and exposed to the elements, on Rapa Nui - also known as Easter Island. A name that dates back to 1722, when a Dutch explorer first saw it on Easter Sunday. The statues, or Moai, were there centuries before that and are sacred to the Rapa Nui people. They have also become a world famous tourist attraction and can be found in multiple outdoor locations across the small island. They are heavy and huge - sizes range from 1 to 20 metres tall. Some are upright on platforms, others are toppled over and broken. Over the years, global weather has become more extreme and is having a devastating effect. Can the statues of Easter Island survive climate change?
