Why have so many companies changed to using paper straws?<|im_end|>
<|im_start|>assistant
Many companies have made the switch to paper straws in order to reduce their environmental impact. Paper straws are more environmentally friendly than plastic straws because they are biodegradable and can be recycled. They also reduce the amount of plastic waste that ends up in landfills and the ocean, which helps to reduce pollution and the impact of plastic on marine life. Additionally, paper straws are often more cost-effective than plastic straws, making them a more economical choice for many businesses.<|im_end|>

But paper straws do melt and ruin the drink at times. Isn't there a substitute material that is also biodegradable?<|im_end|>
<|im_start|>assistant
There are some alternatives. These include bamboo, biodegradeable plastic, pasta straws, among others. Alternatively, you may choose to use metal straws, which are able to be reused and washed as many times as you need.<|im_end|>
