* wrte a letter to a newspaper complaining
about the rampant (uncontrolled) of polythene
bag on your locality.​

Sir,

A walk with any river, lake, and beach is sufficient to know the consequences of thispolythene bag.  Scientists in their recent research have found plastic to be much more toxic than previously expected. Plastic is making our environment highly toxic.

The need is to replace plastic with environmental friendly materials. All of us need to join our hands to fight with this toxic and  preserve our beautiful environment. We must stop using plastic altogether. Thanking you.

Yours truly,

(Your Name)

from the political point of view it could be said that the candidate   is an effective speaker because she takes a strong position on the issue. it is an open discussion but probably she is making a presentation and can choose which subjects she wants to address. she is very likely to attain her aim which is to convince voters to accept her proposal.
