Well done for finding this page! You have already shown tenacity, imagination and great googling skills. This practice doesn't offer work experience, apprenticeships or internships. We're not hiring at the moment. You need to find a slightly bigger organisation for that sort of thing.

Here's some advice and links, which I hope are helpful.

Use your contacts - people you met while studying, both students and staff. Let them know what kind of work you are looking for and what you can offer.
Join a relevant professional body and network like crazy: for environmentalists, IEMA is great. If you have found these pages because you're interested in facilitating then check out the IAF. And if you want to spread your wings into coaching, organisational consultancy and change management check out AMED.
Linked-In is good too - look for active discussion groups related to your interests and location.

If you can afford it, look for volunteering or internship opportunities with organisations relevant to the kind of work you are interested in.

The field of change for sustainable development is one I have found exciting, challenging and satisfying. I hope you find a place here too.

Good luck!
