Scary rubbish statistics!

How long does it take rubbish to break down?  

Today we predicted how long we think it takes for various rubbish items to break down in a landfill.  We were VERY surprised to see the actual estimations that scientists have made.  The statistics made us think very differently about buying products and throwing things away.  

Remember to REDUCE, REUSE, RECYCLE

Wow Room 16 you have done a great job collecting the statistics for these items. I cannot believe that it takes 2-5 years for a cigarette butt to break down.

Well done
