Shampoo Bars and the Environment

“Suppose you currently use 8 shampoo bottles per year. Design a plan to reduce this to 2 bottles per year using shampoo bars. How many shampoo bars would you need to use, assuming each bar replaces 3 bottles? Explain how this change would reduce plastic waste. Imagine you and your family use a total of 15 shampoo bottles each year. If you switch to shampoo bars, and each bar replaces 3 bottles, how many shampoo bars would your family need for the year? Explain how switching to shampoo bars in this scenario would help reduce the amount of plastic ending up in landfills. If you currently use 6 shampoo bottles and 6 conditioner bottles each year, and you switch to using only shampoo bars (no conditioner bottles), how many bottles would you eliminate in total each year? Explain how reducing the number of plastic bottles you use can help reduce the amount of fossil fuels used in manufacturing.”
