The focus of environmental science is to study the interactions between humans and the environment, aiming to understand the complex relationships within ecosystems and the impact of human activities on natural systems. It integrates various disciplines, including biology, ecology, geology, and social sciences, to address environmental issues such as pollution, climate change, biodiversity loss, and resource management. By investigating these challenges, environmental science seeks to promote sustainability, develop conservation strategies, and inform policy-making to ensure a healthier planet for current and future generations.
