Cigarette smoking is far more harmful than just on our bodies. The environment takes a hard blow from cigarettes. Cigarettes contain over 4000 chemicals which are exhaled and released into the atmosphere. Approximately 30% of North Americans are smokers, and a much a higher rate in developing nations. Trees are like lungs, they filter out the pollution in the air, but cannot possibly filter out the added pollution from smoking cigarettes.
Cigarettes impact our environment negatively in more that one way. First of all it affects the land we live on and the water we drink. Cigarette butts by the millions are discarded onto the ground daily. Many end up in rivers and lakes where fish and animals eat them by mistake and quite often die from it. The ones left on the ground to decompose can take an average of 25 years while all of the chemicals and additives leach into the ground and pollute the soil and the plants. Not to mention being a major fire hazard in dry weather.
The actual production of cigarettes can be just as damaging to the environment. Tobacco is a very fragile plant and needs to be sprayed with a lot of potent chemicals and pesticides. It takes a lot of trees to produce and package cigarettes. Cigarette manufacturing uses four miles of paper an hour just for the rolling a packaging process. One tree is wasted for every 300 cigarettes produced. The energy and water wasted in manufacturing also adds a strain to the environment. Trees filter out pollutants and are essential to clean fresh air.
Smoking is a really bad habit to have. It makes the smoker's clothes have a natural smell of cigarettes and also the person's hair and breathe smell terrible. When a smoker smokes for years their teeth begins to turn rotten and yellow, sometimes even black depending on how much they smoked. There is no upside to smoking even though smokers claim it relieves their stress, even if it did relieve their stress there are so many consequences for it. In my opinion, instead of having a habit like smoking to relieve stress why not chew gum or have a stress ball or find another habit that will not harm the body. Perhaps playing sports or lifting weights. While a smoker is at school or work and needs to have a "smoke break" it would be better for them to chew some gum or have a snack, much better for their breathe as well. In my experience chewing gum helped me while confused about something or while I was doing homework and had a lot on my mind to help focus better.
In conclusion, smoking is just a bad habit for the body in general, the nicotine is what what gets the human addicted to the cigarette smoking and it acts like a poison when inside the body. Also smoking can lead to lung cancer and eventually even death. The body and environment are tremendously affected in a negative way. Tobacco companies are not concerned with polluting our bodies, so the environment is really not their priority either.
