I think you stand a much better chance to mobilize society against a million-times-worse problem they've never considered that happens invisibly, far from shore, on the seabed, if you first prime them to agree that the small problem is real.
It's possible that vested interests will try to twist the narrative once it begins to turn against them: "Do your part to sort plastics into bins, not the trash! Pay no attention to the single-use packaging manufacturers generating all that difficult-to-sort, difficult-to-process waste." "Freshwater is a resource that needs to be conserved! Turn the 1 gpm tap off while brushing your teeth. Ignore the 1000 gpm center-pivot industrial farm growing alfalfa in the California desert." etc. but that's risky.
I think that recognizing that invertebrates on the ocean floor can be victims of animal cruelty is step 1 in reducing trawling, pollution, and global warming that harms those animals.
