Environmental economics is a sub-field of economics that focuses on understanding the impact of human activity on the environment and developing policies and strategies to mitigate negative effects and promote sustainability. This area of research examines the economic incentives and disincentives that drive environmental behavior, as well as the costs and benefits of environmental conservation and resource management. Environmental economists analyze how economic policies, such as taxes, subsidies, and regulations, can shape environmental outcomes and promote a more sustainable and efficient use of natural resources. They also study the economic implications of environmental degradation, pollution, climate change, and other environmental challenges. Overall, environmental economics seeks to integrate economic theory with environmental science to address pressing environmental issues and promote sustainable development.
