I've taken Kaylia to her current favourite place for op shops..... Cannington.  It's a bit of a hike but she really likes it because there four op shops..... so she comes home with 20 dvds!  The wall of dvds in her room is becoming critical and unstable.  I expect that soon we'll hear "Ooops" as they fall over.  We then gather them into shopping bags ready to deliver them to the op shops..... and then she can buy them again!

Crazy I know..... but she gets a lot of enjoyment from this.

V. E. E. R. Y interesting

I've just watched a very thought provoking video with a geologist talking about coal.  It seems (no pun intended) that coal was laid down from 360 million years ago.... and then ceased being produced at about 300 million years ago. Why?  When trees first grew and died, there was no biological mechanism to decompose the cellular structure of the trees.  So it remained..... and became coal.  Then after a long period, mechanisms developed that could break down the tree cells...... so there were no longer any un-decomposed trees that could become coal.

This of course means that the earth's resources of coal are finite..... and can't be replaced. 

...... and the same for the fossil fuels that power much of our life.

We must go solar.
