Use much smaller towels everywhere
Use a good quality hand towel to dry off after shower or bath. Any dermatologist will tell you a bit of moisture left on your skin is GOOD anyway. We don't need large towels or beach towels in bathrooms or pool areas and hotels. Laundry, detergent, water and chemical usage all greatly reduced throughout the entire system. Alternately we could just use paper towel and place it in our green bins for compost. Add: time and money saved. It's a no brainer that simply requires making a decision to change today which is instant and well "within a reasonable and practical timeframe."
