What is Environmental sciences?

Environmental Science is the study of the various interactions between the biological, chemical and physical components of our environment with special emphasis on the human influences on these components. Environmental scientists have training that is similar to other physical or life scientists, but is specifically applied to the environment.

Why study Environmental Science at Trinity?

This course has been designed to provide for the needs of students with an interest in this rapidly developing academic and professional field. It comprises specially designed modules plus suitable modules from contributing disciplines. There should be ample choice within the listed optional modules for a selection which reflects a particular student’s interests.

Field work is a core component of the course structure. Students may attend three field excursions in their third year; an introductory field trip in the first week, and in addition, students have the option to take field trips from other disciplines in the School; Zoology offers a field trip in Terrestrial ecology, and Botany offers a field trip which will be based in the Canary Islands.

Student Profile

Maeve Ryan

I decided to study Environmental Sciences as I had an interest in global environmental change and environmental governance. I graduated in 2013, and I am currently studying for an MSc in Environment and Development at King’s College London.

The degree has a wide variety of optional modules to choose from, and this flexibility enabled me to focus on areas related to my career aspirations. The programme also provided me with exciting opportunities. I carried out six weeks of data collection for my dissertation in the Wakatobi Marine National Park (Indonesia) researching how coral structure and function differed in a no-fishing zone compared to a reef located near a village. During final year, I participated in an eleven-day residential field trip to Kenya, which focused on the trade-off between conservation and development in a range of ecosystems.

Overall, I found that the broad background of this programme was a great basis for whichever route within the environmental sector I wanted to take.
