Every disposible nappy that your child has ever used is probably in existance somewhere in landfill. What is more scary is that all these nappies will still exist after you and your grandchildren are dead.
I think that disposable nappies should be seperated from normal rubbish and recyled. I am sure that it would be possible to design a disposible nappy that was more enviromnentally friendly. Maybe a two part system with a water proof wrap and the disposible part could be made completely compostible.
The present situation stinks. I think that it would take legistation to force parents and companies to work a bit harder for the sake of our world.
