so many plastic bags used??

[beppi]

Sorry I don't follow you X9. The article looks at the energy input required to manufacture a cotton shopping bag versus a plastic one. On what basis are you making the 'possibly 5' comparison?

A plastic bag can be used to contain 65 unneeded plastic bags (e.g. for throwing them away).
A cotton bag can only hold (and throw) 13 cotton bags.
Thus a plastic bag is a FIVE times more efficient use of resources!!!

(The discussion has just reached a new low ...)

J8, the comparison was based on the use: 1 plastic bags as compared to 1 cotton bag, but actually it is never the case as you need much more plastic bags to pack your staff after the single shopping than the cotton bags. It is like saying that cars are greener than aeroplanes because to make 1 car you need 3t of CO2 and as much as 300t for the plane and neglecting the No of passengers they carry.

very very wrong. Fundamentally wrong. You can pack 3475.2 plastic bags into one cotton bag while you cannot pack more than 3 cotton bags into a plastic bag as it will get damaged. The damaged plastic bags influence the airflow around the shoppers increasing their movement resistance what directly causes increase of emission of 2.3kg CO2 per 100 m of traveling distance.

Oh my...
Now you have to deal with JR8. He will give you lessons from basic, intermediate to advanced... Or you just go through all the posts in this thread. Enjoy!

I like your sense of humour - quite unexpected for a Chinese AND for somebody who lived in Germany 9 years!

(I am German myself, and I don't even know how to SMILE!)

Thanks for the compliment.
But I call your post humour too. So you did have it.
