The journalist and author Fred Pearce, Oxfam campaigns and policy director Phil Bloomer and ESRC associate research director Paul Rouse are among those to tell us about their one big hope for Rio+20 at the Planet Under Pressure conference in London this week. We’re asking people at Planet Under Pressure and other events to tell us what sustainable development issue they want to see addressed at the Rio+20 Earth Summit in June.We were particularly glad to have caught the thoughts of some of the evetn’s youth organisers on camera.

If you are at PUP, you can record your response at our stand in the exhibitor area. but if you are not in London, we’d love to include your views. You can comment on this blog, or send us your videos to feature. Email us at [email protected]
