Environment - Steven (I don't know his last name)

On 15th May 2019 Steven came in and talked about how he helped the environment. First he started new business that I forgot what it's called. He made reusable cups and made people rent it at a stadium like: AMI Stadium, Horn castle Arena and more! And at those games, instead of other people using non-reusable cups he gave them his cups so they don't throw them in the bin, or the ground. At first, lot's of people thought it was useless then they showed them a image of what it looks like after the game. After that people realised that they should use the reusable cups and started using them. Still some people were like this is stupid and then a person turned around and says, "Hey, don't say that. We've been throwing rubbish on the ground so you should start using these cups!" 
He said that pretty much every game over 100 people uses his cups.

Question:
Would you rather choose plastic non-reusable cups or reusable cups?
