Goal # 6: Clean water and sanitation means that the water is poor and unhealthy and the water needs to be cleaned. If we clean the water or sanitize the water, then the water will become clean and healthy and safe to drink. This goal is important because we need water to help our crops grow so we can eat, animals need water and us humans use water for many things. If we don’t fix this problem, crops will die out, people and the animals will get sick of dirty water and could possibly die. We need to clean the water so animals, crops, and us people can live.
