Trinity College Green Week is taking place now, with events running until Friday.
It is an annual celebration of nature, and provides a forum for Trinity staff and students to share ideas on how to protect the environment, within and outside College.
Nature events include guided walks where you can find out about the birds, trees and buildings in College and how they can be affected by human activity.
Other events are aimed at finding ways of minimising environmental impact, and include the Simon Perry memorial symposium, a debate, and a competition for the best environmental initiative.
A detailed programme has been published and is available here Green Week 2010 Programme of Events.
