Why we can and must Recycle Everything!
We've all heard of peak oil, but what about peak hafnium, or peak terbium, peak silver or peak lead? Hafnium, which is important in computer chips, could be depleted by 2017, and terbium, used in florescent light bulbs, by 2012. Silver could be impossible to find in 4 to 29 years, and lead in 8 to 42 years.
