Now we know that CO2 is aerial fertilizer and feeds the world, but this study highlights the crazy unscientific randomness of environmental policies chanted by the same people who say "follow the science".

It turns out paper shopping bags produce five times as much CO2 over their lifetime as plastic HDPE bags do. Apparently, plastic bags might strangle a turtle, but in the mind of a dedicated Green, paper bags could be causing the sixth mass extinction. Oh the dilemma?

A new study in Environmental Science and Technology looked at 16 applications of plastics in modern life found that in 15 of them, the plastic version produced fewer emissions than the paper, concrete, steel, glass or aluminum sort. And these 16 applications accounted for about 90% of global plastic volume. It seems that with paper bags people often "double bag" their groceries because the bags are prone to breaking, and in the end, in landfill, the paper waste is degraded into methane.
