I found an email from Sierra Club one morning about the reuse of paper bags instead of plastic bags in terms of reducing the carbon footprints; something I was curious about all along while preferring the paper bags and reusing them to the plastic bags.
Contrary to my belief that I was being more environment friendly, according to the information, polypropylene plastic is bio-degradable and widely used, and I must reuse paper bags up to 14 times to match the carbon footprints that this plastic leaves.
This is a new knowledge for me. Now I know that I can choose plastics that are environmentally friendly and right for certain purposes, and that I must reuse paper bags many more times in order to reduce their impact on the environment.
I might even investigate more on carbon footprints of materials that I commonly use to gain accurate knowledge to truly help the environment after this experience.
