On 1 January 2040, thanks to the work of the IUCN, WWF, and people from all areas of life over the last 20 years. Led by the G20, nearly 80% of the world's countries and regions have signed the "Breathing Agreement" in the cloud. To control and preserve the balance., the WORLD BREATHING ALLIANCE was established.

Main content:
1. Each month, a certain amount of clean air is supplied to various countries or regions across the world, although it is limited, anyone in that country or region can use it.
2. In addition to the consumption tax on all commodities, a new tax added to daily life is the respiratory tax.

Everyone has a fixed share of breath each month, and a country or region decides how to distribute it. It can be utilized for everyday breathing, as well as for exchanging free masks, and disinfection products, and deducting the share of the price increase of products brought on by the breathing tax. Companies should offer employees respiratory tax subsidies in addition to the current transportation and lunch subsidies.
