Nature's Voice

The Rio+20 Earth Summit may not have seen a giant leap forward for the environment, but as the RSPB's Sacha Cleminson tells Jane Markham on this edition of the Nature's Voice, it has perhaps nudged the agenda forward.  We also assess a new report calling for a woodland culture for the 21st century to restore our ailing woodlands. And why not step up for nature and create a woodland glade in your garden - even if it's tiny!
