Edible paper mmmmmmmm! (its disgusting)

I was a bit stuck, really stuck, wasnt sure how to include stuff like global warming, etc.
Im finding it a bit difficult not having any feed back throughout the project, cant be 100% sure if im going the right way!
I thought about making my work environmentally friendly - i experimented with painting with strawberry juice, papers that would biodegrade quickly, like rice paper, and edible wafer paper, handmade papers with flowers and leaves in it, but im not sure if im allowed to print on different paper coz its got to go in a book?!
I also tried out stencils with spray paint, letting it drip, the effects made the flowers look decaying and dead . . ..
