A city is considering banning plastic straws to reduce ocean pollution. A critic argues that because plastic straws make up less than 1% of total ocean plastic by weight, the ban will be ineffective at protecting marine ecosystems.
Which of the following, if true, most weakens the critic's argument?
- Plastic drinking straws are seldom recycled effectively and frequently end up scattered across landfills as well as in oceans worldwide.
- Paper, bamboo, and various other reusable straw alternatives are steadily becoming more affordable for most restaurants to purchase in bulk.
- Many comparably sized coastal cities elsewhere in the same region have already quietly implemented their own plastic-straw bans in recent years.
- Plastic straws are among the most lethal forms of ocean plastic for marine life because their size makes them easy for animals to ingest.
- Banning plastic drinking straws on its own will completely eliminate every single existing threat now facing marine ecosystems.
