Environmental legislation is the comprehensive body of laws, regulations, treaties, and legal principles enacted by governmental and international bodies to protect the natural environment and regulate human activities impacting it. As a research field, it investigates the formulation, implementation, enforcement, and evaluation of these legal frameworks, analyzing their effectiveness in addressing environmental problems such as pollution, resource depletion, and biodiversity loss. Its significance lies in providing a legal basis for environmental governance, promoting sustainable practices, and establishing mechanisms for accountability and remediation.
