3R's principle in the context of use of plastics means we must try to Reduce, Reuse and Recycle the use of plastic items. We must develop the habits which are environment-friendly. In order to achieve this, we must not throw plastic in the water bodies or on the roads. We must take a cotton carry bag or a jute bag while shopping. We must try to minimize the use of plastic materials. For example, we must use a steel lunch box or steel containers instead of plastic ones.
