NAFTA is an agreement between the US, Canada, and Mexico that established a North American trade bloc and eliminated many tariffs to facilitate the movement of goods and services. It aims to promote fair competition, increase investment, and protect intellectual property rights. Related agreements were also formed to foster environmental cooperation (NAAEC) and protect workers' rights (NAALC). While NAFTA increased trade, productivity, and incomes in member countries, it also resulted in job losses in some sectors and increased inequality and migration. Overall, it played an important role in the development of North America but also had some adverse effects.
