No, Capri-Sonne should not change the paper straws back to plastic straws. Plastic straws are harmful to the environment and contribute to pollution, while paper straws are more eco-friendly and biodegradable.

Straws are typically round because a round shape allows for easier suction and flow of liquids. The circular shape creates a smooth, continuous path for the liquid to travel through without getting stuck or blocked. Additionally, a round shape is more structurally sound and less likely to collapse or bend during use. Overall, the round shape of straws is designed to provide a convenient and efficient way to consume beverages. **

Plastic straws are harmful to the environment as they contribute to plastic pollution and can harm marine life. Paper straws are a more environmentally friendly alternative as they are biodegradable and can be easily recycled. Therefore, choosing paper straws over plastic straws is a more sustainable choice for reducing environmental impact. **
