Infographic illustration depicting the economic value of the ocean. The value of the world's oceans can be divided into four asset categories: direct output such as fishing (USD 6.9 trillion), trade and transport (USD 5.2 trillion), productive coastline activities such as tourism (USD 7.8 trillion) and carbon absorption (USD 4.3 trillion). Collectively this makes the oceans the world's seventh largest economy. Data based on 2018 WWF report on a Sustainable Blue Economy.
