Why the hell would you ever buy anything disposable anyway?! Such things are always cheap and shoddy by their very nature, but above all they are the most anti-ecological thing you could ever do.
Think about it; who pays for the cost of disposing of the item? – you do ofcourse! This means that the manufacturer has shifted the cost of getting rid of their junk from their pocket to yours.
In my opinion all disposable items should incur a tax rate of 100% – but only if that money was ploughed back into the environment. At the very least you should stop buying disposable stuff and pay that little bit extra for an item that will last a lot longer – and then make sure at the end of it’s life you recycle it!
