The Port of Nagoya Public Aquarium is now roughly 3.5 billion years since the earth was born. Over the ages many varied life forms developed in nature's great aquarium, the ocean. Humanity was born receiving the riches of the ocean and coming to understand the mystery and sacredness of life. Now as the destruction of the natural world is becoming ever more serious, people must fully recognize our shared treasure that is the ocean, and think about how best to live symbiotically. The first step we can take is to connect with and learn about many types of life.
