Rivers first for ocean plastic — Tutorial

Most ocean plastic arrives through rivers — catch it there, and clean the big floating patches separately. Trash is easier to guide in a river channel than after it fans out at sea. Ocean barriers clean floating plastic that already escaped. Cleanup helps — it does not stop plastic production or vacuum microplastics by itself.

Page Title Concept (one line) When the tutor offers it Illustration
01 Plastic rides rivers into the ocean Most manageable floating ocean plastic travels through rivers first. First beat, before catch mechanics. 01
02 Catch, then lift to shore Barrier → extract → shore waste path. After rivers; before local instance. 02
03 A real river needs a shore path Barriers plus a shore machine only work with a local waste path. After mechanism; before ocean job. 03
04 Ocean patches need a different machine Ship-towed ocean barriers clean legacy floating plastic — not a river catch. After local catch; before the one idea. 04
05 Two jobs, not one Most ocean plastic arrives through rivers — catch it there, and clean the big floating patches separately. Core one idea after both jobs are clear. 05
06 Cleanup is useful — not a full fix Production, microplastics, waste systems, and hard questions remain. After the one idea; before invent. 06
07 Invent a way this river mouth stops feeding the ocean Open invent for a river-mouth coast — no prescribed brand. Last page / invent gate. —
