The people in Japan have adapted to their environment by tightening environmental legislation. They have also taken a much more proactive (acting in advance to deal with an unexpected difficulty) approach to waste management. they adapted by eating sushi. which is cold cooked rice dressed with vinegar that is cut down to bite size pieces and topped with cooked or raw fish. it is also sometimes formed into a roll with vegetables, fish, or egg and it's wrapped in seaweed. the ocean is the most provided source for food.
