<human>:  What can you tell me about the European Union?
<bot>: The European Union (EU) is a political and economic union of 28 member states that are located primarily in Europe. It has developed a single market through a standardized system of laws that apply in all member states, enabling the free movement of people, goods, services, and capital. The EU's goal is to promote peace, prosperity, and economic stability within its member countries. It also works to ensure the conservation of natural resources and the protection of human rights. It also provides mechanisms for cooperation in areas such as justice and home affairs, foreign policy, and human rights. Additionally, the EU has fostered a single currency – the Euro – that is used by most of its member countries.
