Try to focus on the positive rather than the negative. Make the problem clear, but don’t fall into the trap of finger-pointing, express concern rather than anger. Personally i don’t like the space-narrative in there. Better keep it down to earth. Would expect this to work better for your intended audience here.
How about showing a contrast instead, something nice that would appeal to people, rally them to your cause. Like, after the depressing footage of birds covered in oil, cut to a desert turning into a lush green environment using FF desalination plants. Could have a bird flying around there as a backreference 😉
Maybe use excerpts from the latest oval office address concerning the oil spill, and Pres. Obama’s call to make a push for clean energy?
