On top of the fact that plastic is systematically destroying our earth one molecule at a time and stuff, using saran wrap is an enormous pain in the ass. It tears off the roll all jagged and jacked--if it tears off at all, and if you're lucky enough not to gouge out 3 or 4 layers of flesh on the box's serrated metal teeth in the process--and then just sticks all over everything, including itself, until you actually need it to stick to something, at which point it loses any semblance of adhesive properties altogether.
Now aluminum foil, on the other hand, I love. That stuff does whatever I tell it to, including transforming into an awesome silver spider yamaka with the help of some scissors and a surgical mask. But like plastic wrap it's not really any better for the environment. Abeego, on the other hand, is a completely natural, eco-friendly food preservation wrap. It's made of hemp, cotton, tree resin, jojoba oil, and for the requisite storage stickiness, beeswax. Its flat sheets mold and shape easily over a variety of items, both organic (cheese, watermelon, sandwiches) and inorganic (bowls, plates, and other kitchenware).
Abeego adheres in response to pressure and the warmth of your hands and forms a liquid- and air-resistant shield once in place. It's also washable and reusable. This set of beeswax wrappers includes a 7" square, a 10" square, and a 13" square.
