The Sami people live in northern Europe where it is cold whereas I live in southern Europe where it is warmer. The Sami people catch fish and hunt reindeer whereas my family and I get our food from shops. The climate change is seriously threatening the Sami people’s way of life whereas our lifestyle is not threatened.
