What's the relationship between environmental science and environmental sustainability?

Environmental science typically covers human impacts on land, air, water, and ice as well as current environmental issues (e.g., global warming, acid raid, ozone hole, overfishing, etc.) with an emphasis on comprehending the processes that operate in the natural environment.

Environmental sustainability is a discipline that focuses on sustainability from a slightly broader perspective. It studies concepts such as the environment, economy, and society (sometimes referred to as people, planet, and profit). It also covers strategies and solutions that society can use to achieve environmental sustainability.

Having said that, it is typical for environmental courses at most universities to include a single course covering both the science and sustainability aspects.

Environmental science is the interdisciplinary study of the physical, chemical, and biological processes that occur in the environment and how they are influenced by human activities. Environmental sustainability, on the other hand, is the goal of ensuring that human activities and resource use are maintained in a way that meets the needs of the present without compromising the ability of future generations to meet their own needs. Environmental science provides the knowledge and understanding necessary to assess the current state of the environment, identify environmental problems and their causes, and develop solutions to promote environmental sustainability. In essence, environmental science informs the pursuit of environmental sustainability by providing the scientific basis for informed decision-making and action.
