Commitment #31 of 93 - I will reuse hotel towels and linens rather than having them washed every day

What would be the impact if every Kanu member said yes to I will reuse hotel towels and linens rather than having them washed every day? Over the course of a year, our commitments will conserve 257,741 gallons of drinking water. The amount saved is enough drinking water to keep everyone in Kaimuki, Oahu alive for 0.8 month.
