It is very common for everyone to think that the National/Global link means the respective review boards want to see how the Cadettes are going to make their projects national or global. This is not the case. We hope that takes a lot of pressure off!
National/Global (N/G) Link: the intention of this category is to reflect on how you see the problem/issue on a national/global scale. Where else is it seen? Are there any similarities to how you see the local problem? Are there any differences? What, if any, are other people doing to solve the problem/issue for their area? Do they see any different root causes that they are addressing? Usually, it's just a simple google search and looking at different articles or websites and referring to their statistics and other information.
At the Bronze & Silver Award (and Cadette journey and below) level it is optional. So just going through the motions of the exercise is all that is needed (if that’s what they want to do). If a Silver Award proposal writer wants to share, they may in the optional field. They would give a sentence or two on what the Girl Scout/Group discovered. They may discover that their issue is not really National/Global-and that is ok at the Silver Award level.
