The scientific field that studies the effects of human activities on the environment is known as environmental science. This interdisciplinary field combines knowledge from natural sciences, social sciences, and humanities to understand how human actions impact ecosystems, biodiversity, and natural resources. Environmental scientists assess issues such as pollution, climate change, and resource depletion, aiming to develop sustainable solutions to mitigate negative impacts. The field is critical for informing public policy, conservation efforts, and environmental protection initiatives that strive to balance human needs with ecological health.
