Convincing people to stop using plastic

In class, we have been learning about plastic in our ocean, how we can stop plastic pollution, and how it is affecting our sea life. This plastic is getting into our ocean and our sea life are mistaking these plastics for food and eating it. Eventually, that fish will end up on someone's dinner plate. Seabirds are also getting this plastic and feeding it to there baby birds. Sea life will eventually die from starvation after digesting the rubbish they ate.
