Single Steam Recycling: how it works

A few people  have asked me recently about how single stream recycling works since its a better method for recycling.  (which has developed since in general people don’t seem to understand how to sort and not put trash in recycle bins, especially on my campus!)

This awesome Web site  www.explorethecycle.com offers simply explained, short video clips demonstrating “the cycle” and “the MRF” (and by visiting their site you can also watch clips on paper, glass, metal, plastic and overseas!)

Wired Science: Time-Lapse Videos of Massive Change on Earth

I thought it was worth sharing these interesting (hmmm??) videos from NASA’s Earth Observatory satellites capturing (over time) human destruction of the planet from deforestation, irrigation and urbanization. Here is one called Sucking Out the Aral Sea:

In the 1960s, central Asia’s Aral Sea was the fourth largest lake in the world. As a result of irrigation and damming, it had shriveled to 10 percent of its original size (marked by the thin black line) by 2007. It is now three separate, highly salinic, lakes.
