Grass

As one of my summer holidays projects, I have done grass.  Most people think of it as a weed, but after watching ‘How to Grow a Planet’, I changed my mind. Read the pdf document and learn about the amazing evolutionary history of grass: how it battled against giant trees (and won, with fire), staved off herbivores (for a while) and helped spark human civilization (by starting farming).  Once you have read it, you should still watch ‘How to Grow a Planet’, it is very interesting.
