The Guardian on Flickr PRO 11:42am, 1 May 2012
Twenty years after the Earth Summit in Rio de Janeiro, politicians, businesses, activists, NGOs and more will meet again for Rio+20. The UN describes the conference as ‘a historic opportunity to define pathways to a safer, more equitable, cleaner, greener and more prosperous world for all’. So what path should we be heading down, or avoiding?

We’d love to see your messages from around the world submitted to our Flickr group. We'll feature some of our favourites on and maybe in the print version of the Guardian as well. For inspiration, take a look at these brilliant galleries of readers’ global education messages or Messages to UN Women.

Rio+20 has two themes a green economy in the context of sustainable development poverty eradication and the the institutional framework for sustainable development. As part of these, seven priority areas:
- decent jobs
- energy
- sustainable cities
- food security
- sustainable agriculture
- water
- oceans
- disaster readiness

Which of these matters most to you? Maybe you think decent jobs are the key, or that urbanisation means our cities must be the focus? Or perhaps you think a key theme is missing? We'd love to see your messages in pictures submitted here, or to if you have any problems submitting them on Flickr. Head to the development site to find out more about how we'll be covering this, and to send your message.

Please note - By posting your pictures in this group, or sending it to us in response to this request, you agree to let us use it on our site and potentially in the newspaper (though copyright remains with you at all times, and you will be credited).

Can't wait to see your pictures!
