I believe that individual should play a more critical role in environmental protection.Some may argue that what one person does may not really matter, and one individual’s effort can’ t make a sustainable change. However, in reality, when you add up what each does, it may make a big different. Once one individual effort reach a certain scale, it’ s like a snow-ball effect, which will make our environment a whole lot better. Take waste management in china and japan as an example, these country has implemented categorization system. Educating citizen the important of sorting their garbage, encourage them to recycle item like plastic, paper, metal, and glass. Therefore, there are increasing number of people adopting environmental-friendly practice now, which not only reduce the mount of waste ends in landfills, but also promotes people environmental awareness, since it’s something they are required to do daily.
