There is nothing like the Lens Artist Photo Challenge to make me feel all philosophical. This week’s theme is It’s A Wonderful World. I have decided to focus on water because water is awesome. It’s essential to our being. Earth is the only terrestrial planet in our solar system that has liquid water at its surface.

Apart from Antarctica, Australia is the continent with the least rainfall. At the first hint of rain at the end of the recent horror drought in south-eastern Australia, swarms of flies emerged to drink from the puddles in still dry dams. How awesome is that?
