The chief of child psychiatry where I work is a quirky fellow. Hes a psychiatrist, but is also interested in collecting coffins at antique shops, singing in a choir, and seeing offkilter movies. But I think he maybe onto something especially when it comes to the environment. He was talking about Soylent Green which is made from sea plankton and maybe helpful for the environment. Although it may taste like "nautilus crud" it may be the answer for the ambiguous hole in the ozone layer. You can also read more about it Here
UPDATE: Or just watch.
