Saving the planet

Something somewhere has gone wrong.

Everywhere we look we are being told that we have to save the planet and unless we do the latest GREEN fad we are all doomed, as Corporal Fraser used to say (Don't know who he is? oh dear I am getting old).

There are some things that seem good ideas, recycle what you can, don't waste things and respect the environment but something I saw the other day just didn't seem right.
Written on a pack of dustbin bags it says "Biodegradable - this bag will degrade 30 times faster than any other" . My black bag rubbish consists of all the things that I can not recycle including the wrong types of plastic, that take a billion years to degrade, anything that's broken and has a mixture of metal and plastics etc. But now I can throw them all into landfill safe in the knowledge that although they will be there for ever the bag they are in will degrade virtually as they hit the ground.
What a great idea.
It isn't just me is it, this really is a total waste of the extra money they cost?
