环境科学与工程（ESE）是一个跨学科计划，旨在理解，预测和响应自然和人为环境变化。解决环境问题，例如全球变暖，平流层臭氧消耗或局部和区域的空气和水污染，需要来自多种科学学科的观点，包括大气物理学和化学，海洋学，冰川学，水文学，地球物理学，生态学和生物地球化学。我们将环境视为化学，物理和生物相互作用的复杂集合，人类社会的各种活动使环境变得更加复杂。通过探索地球系统中的基本过程和反馈，并采用从理论和建模到实验和观察的一系列方法，我们训练学生以综合的方式思考环境过程，为他们应对我们面临的环境挑战做好准备。<br
Environmental Science and Engineering (ESE) AB and SB interdisciplinary programs focus on understanding, predicting, and responding to environmental problems. Students receive strong and broad training in physics, chemistry, engineering, ecology, and mathematical modeling, in a way that makes them uniquely understand the connections needed to solve environmental problems. They take advanced classes in energy systems, climate science, hydrology, and environmental pollutants. They gain hands-on experience through field, laboratory, computer modeling, and big data projects, working with ESE faculty who are world leaders in their fields. They can also carry out projects with faculty in other areas of SEAS.<br><br>At Harvard College, students choose a concentration, which is what we call a major. All prospective undergraduate students, including those intending to study engineering and applied sciences, apply directly to Harvard College. During your sophomore spring youll declare a concentration, or field of study. You may choose from 50 concentrations and 49 secondary field (from Harvard DSO website).
