The measures to be taken to keep public places clean and free from plastic are:
try using cotton or jute bags instead of plastic bags.
It is better to recycle the plastic waste. Most of the thermoplastics can be recycled. As a responsible citizen we should remember the 4 R principle. reduce, reuse, recycle and recover. Develop habits which are environment friendly.
Do not throw plastic bags in the water bodies or on the road. Take a cotton carry-bag or a jute bag while going for shopping. Try to minimise the use of plastic materials e.g., use a steel lunch box instead of a plastic one.
