We now breathe, drink, eat and wear petrochemicals every where, every moment, every day! There’s no getting away from them!
Where are they coming from?
“The petroleum industry includes the global processes of exploration, extraction, refining, transporting (often by oil tankers and pipelines), and marketing petroleum products… Petroleum (oil) is also the raw material for many chemical products, including pharmaceuticals, solvents, fertilizers, pesticides, and plastics.”
(https://en.wikipedia.org/wiki/Petroleum_industry)

So many of the things we use (and consume) are being made from petrochemicals.
Seriously "Sensitive" to Pollution
