How does Environmental Engineering differ from Environmental Science?
While both fields are concerned with the environment, environmental engineering focuses on applying engineering principles to solve environmental problems, while environmental science focuses on studying the natural environment and its interactions. Environmental scientists conduct research, collect data, and analyze environmental issues, whereas environmental engineers use this information to design and implement solutions. Think of it this way: environmental scientists diagnose the problem, and environmental engineers prescribe the cure.
What are some of the challenges facing Environmental Engineers today?
Environmental engineers face a number of challenges, including:
- Climate change: Developing strategies to mitigate greenhouse gas emissions and adapt to the impacts of climate change.
- Resource depletion: Finding sustainable ways to manage and conserve natural resources.
