Gotta love Trog!
Truly, he is right. The more humans killed off the better the planet is. However, I have to side with the e-cig as being better for the environment. Yes, it is probably true that the manufacturing plants of ecigs produce unwanted items into the environment, but the same can be said for tobacco cigarette manufacturing as well. So in this respect, until there is a study that compares the waste from both, I see them as equal contributors.
As far as the waste from the actual ecig. We do have the lithium ion batteries, but if disposed of properly, they can be recycled. Do we have recycling for lithium ion batteries? Sure!
Battery Disposal Guide for Households - Where to Safely Recycle Used Batteries. Are you going to have to make an effort? Yes you are. But good greenies will do it no matter what. Recycle!
As far as the plastic mouthpieces, it is my understanding they are made from #1 type plastic which means if you remove the fiber filling, you can throw them into the recycling bin at home. AND I should also mention that you can reuse them until they fall apart and even clean them with a light water and soap solution. Reuse!
As far as the e-cig as a whole, you can minimize the amount of cigarettes you smoke by reusing the same unit until it's death so there is the final R. Reduce!
Cigarette butts contain traces of all of the sh*t they put into them. So not only do you have a cigarette .... that will never break down, but you have all of these horrible things leaching into the ground.
CigaretteLitter.Org - The Facts About Cigarette Butts and Litter - Facts. People assume that they are made of materials that will eventually break down because it feels kind of like cotton. A battery, is a battery and because it is metal, people automatically will not just throw it on the ground.
Second Hand Smoke (SHS) also contains a multitude of items including arsenic, benzene, and many more items
Secondhand Smoke: Questions and Answers - National Cancer Institute. All of these not only are harmful to humans, but also harmful to the environment.
Currently, we know that the resulting vapor of the electronic cigarette includes nicotine, propylene glycol and water. Nicotine and water are obviously natural to the earth and propylene glycol is an organic compound mostly composed of carbon, which I do believe is naturally occurring in the environment as well (someone might want to yeah or nay this.)
So my final verdict: The electronic cigarette is definitely far more eco-friendly than the tobacco cigarette. Holy hell! I just wrote a post for my green blog! WOO!
