I have never been the kind of high-minded person who shouted about the need to protect Mother Nature. I found all the arguments a bit too much. However, I have started to care about these issues because of concern about my health.
I suffer from a nasal allergy and am affected by emissions from car exhausts and from people smoking outside.
On those days when the air quality is really bad, I have difficulty with my breathing and my nasal passages are congested.
I wish smokers would think about other citizens who are affected by second-hand smoke and would not light up in public.
Also, I urge those with private cars to try wherever possible to use public transport.
Think about the health of your fellow citizens and of the planet.
