Environmental models are used to simulate and predict the behavior of complex environmental systems, such as ecosystems, air quality, and climate change. These models are used to better understand the interactions between different components of the environment and to support decision-making for environmental management and policy. Environmental models can range from simple conceptual models to complex mathematical simulations, and can be used for a variety of purposes, such as predicting the impacts of human activities on the environment, assessing the effectiveness of environmental policies, and identifying potential solutions to environmental challenges. Overall, environmental models play a crucial role in helping scientists and policymakers understand and address environmental issues.
