Final answer:
Agreements between states for resource regulation or protection are known as interstate compacts or international treaties. These agreements include environmental protection measures and economic relations, such as the Paris Climate Accord and various trade agreements.
Step-by-step explanation:
Agreements among two or more states to regulate the use or protection of certain resources, such as water or oil and gas, are typically referred to as interstate compacts or international treaties, depending on whether the states are within the same country or are sovereign nations, respectively. These accords can cover a variety of subjects, from environmental protection to the regulation of trade and the sharing of resources. For example, the Paris Climate Accord requires states to modify their domestic policies to address climate change; the prohibition of drilling beneath state-owned waters for oil and natural gas protects environmental resources; and trade agreements can reduce tariffs and nontariff barriers to foster economic cooperation. These agreements are essential in coordinating efforts to manage shared resources and protect the environment.
