There are some major sources of beach debris such as beach users, oceans, sea drifts, and river flow. Many beach users leave their litter behind on the beaches after activities. Also, marine debris or chemicals such as raw oil drift from oceans or seas and accumulate on beaches. Additionally, many rivers bring some cities' trashes to beaches. These pollutants harm marine life and ecology, human health, and coastal tourism.[3] Hartley et al.'s (2015) study shows that environmental education is important to eliminate many beach pollutants on beaches and the marine environment.[4]
