Plastic is a huge problem - not just in terms of it being made from a finite resource (oil), or going into landfill, or choking wildlife, but in terms of its long-term effect on the entire planet.
There are huge floating islands of plastic the size of Europe in the world's oceans, but few people seem to give a damn. The plastic doesn't biodegrade, it simply gets smaller and smaller, finds its way into the food chain and eventually gets it us where it does very nasty things to the human body.
Scientists have found bits of plastic that can be traced back to World War 2 in these plastic islands. Plastics last in the environment for hundreds of years and carry all matter of toxins with them and within them.
So don't be taken in by the plastic bag versus paper bag propaganda put out by the plastic packaging industry. All plastics, including packaging and bags, will be out there polluting the environment for a long time.
I only just found this thread or I would have referred to it on my blog today. Earlier today I posted about
Trashlantis found, and referred back to a much more detailed post on seaborne plastic pollution,
Trashlantis - the kingdom of plastic. Read the second post in particular and then do something.
