Finding effective cleanup methods is not enough to protect the environment. We should try to address the core problem, which in fact is the problem of public awareness in terms of ocean pollution. In order to reduce trash that makes its way into the oceans and causes ocean pollution, a beach cleanup tool NEREUS that conveys the message of environmental protection is created. NEREUS is a beach cleanup tool with a slogan "LOVE THE OCEAN & PICK UP GARBAGE" carved on its tire skin. NEREUS not only achieves purification of the beaches, but also promotes the concept of ocean protection. Thoughts can change behaviors, and behaviors can prevent marine debris, encourage the public to pick up the garbage. Only by enhancing the public awareness of environmental protection can the problem of marine pollution be improved.
