The 2012 Rio+20 Earth Summit is an opportunity for us to redefine our relationship to development and the environment. Working with groups from around the world, the MobilizeUS! team has developed a top 10 asks for Rio+20 to ensure healthy communities, a healthy environment, and dignity for all.  We need your help in supporting these building blocks to sustainable development, helping to highlight the importance of the environment in our media, and making sure our elected officials represent us at Rio+20 and beyond.
