Ecology Challenge: What is wrong with Straws?

Research plastic straws and why they are an environmental problem. Come up with three reasons why they are a problem. Create a short Google slides presentation depicting the problem with straws. Develop possible solutions to this problem. Your solution must be something that you could actually change in your own day to day life. Include this at the end of your slide show. Make sure you use multiple sources to find your information and document what websites you used on your last slide.
