Green Wales: What's the Point?

How realistic is going green for most of us? Sarah Dickins explores what changes some people in Wales are already making.

In Cardiff and Cwmtillery going green means getting muddy, while in Newport Sarah meets students who are making green high street fashion from throwaways.
