The climate crisis continues getting worse, 120 nations in the world, including Europe, United States, China, Japan, and Korea and more than 70% global economies, all propose the commitment of achieving net zero emission in 2050. Other than reducing the global gas emission produced by human beings, it is also very important to support the carbon sink system and promote the carbon cycle in the natural world. Scientists call the forests and woods on the land “green carbon” and the ecology in the ocean that can seal carbon “blue carbon”. Our efforts in conserving the land ecology and protect marine habitat will be able to strengthen the capacity of carbon fixation and storage on the land and in the sea. It will bring great help to reducing and slowing down the global warming. 2022 Green Expo Agricultural Experiment School uses 2050 net zero carbon emission as the framework of landscaping. Green carbon plants terraced fields and floral sea are sued to describe the image of blue sea carbon fixation by a giant whale. We support carbon sink from both land and sea to promote natural carbon cycle.
