This video isn't really about sustainability, but it does show you a lot about what goes into a toaster. Thomas Thwaites decided to make his own toaster from scratch. This meant that he mined his own iron and copper, and even made the plastic cover out of oil.
His video really made me think of all the stuff that is in every product we buy. He said that his first step was to buy a toaster and take it apart. He found about 400 different pieces in the cheapest toaster he could find. I wonder how many are in the expensive ones?
And just think, when the toasters go out, where do people dispose of them?... The landfill.
