I believe that 3R requires the involvement of all levels of the society.
I cannot agree more that as consumers we must be mindful of our own consumption habits. We must stick to buying only what's necessary and chosing wisely in terms of quality for our own health and the environment. This is the first step and one that each of us can practice.
At another level, all plastics that are manufactured needs to be easily and quickly decomposable / biodegradable or at least environmental friendly. This stage requires the cooperation between plastic producing companies and the authorities.
May the efforts of preserving our earth become one that is seriously undertaken and with sincere concerns and actions.
