The first paragraph provides more sound arguments because it focuses on the negative environmental impacts of plastic bags and the potential benefits of banning them. It acknowledges that plastic bags are not a necessity and that there are alternatives, such as paper bags and reusable cloth bags. It also emphasizes the importance of taking action to reduce pollution and protect wildlife. The second paragraph, on the other hand, focuses on the benefits of plastic bags, such as saving trees, keeping food fresher for longer, being cheaper to ship, and being safer than glass. While these are valid points, they do not outweigh the environmental damage caused by plastic bags. Therefore, the first paragraph provides more sound arguments.
