When studying cattle and beef trade between the United States and Mexico, we discovered a problem related to economic inequality. The United States buys calves from Mexico at low prices and sells them to Mexico at higher prices after raising them. This approach leads to such a relationship becoming very fragile if there are policy or climate issues. We hope to build a new system to alleviate problems that may arise. The purpose of the project is to increase the value of cattle while treating cattle as an equal life. We found that the project not only increases the value of cattle but also improves the development of the countryside near the border.
