Environmental biology is the study of the relationships between living organisms and their environments. This interdisciplinary field combines principles from biology, ecology, and environmental science to understand how organisms interact with each other and their surroundings. It explores how various environmental factors such as climate, habitat, and human activities influence biological processes and ecosystems.

One key area of environmental biology is the study of ecosystems, including the dynamics of energy flow, nutrient cycling, and species interactions. Researchers examine how different species contribute to ecosystem services such as pollination, water purification, and soil fertility. This knowledge is crucial for conserving biodiversity and managing natural resources sustainably.

Another focus is the impact of environmental changes on species and habitats. Environmental biologists study how factors like climate change, pollution, habitat destruction, and invasive species affect ecological balance and species survival. Understanding these impacts helps in developing strategies for ecosystem restoration and species conservation.

Environmental biology also addresses the role of humans in shaping ecosystems. It involves assessing the effects of human activities, such as urbanization, agriculture, and deforestation, on ecological health and developing sustainable practices to minimize negative impacts.

Through research and application, environmental biology contributes to environmental conservation, policy development, and public awareness. By integrating biological knowledge with environmental management, this field plays a crucial role in promoting ecological sustainability and protecting the natural world.
