‘Dredger’ reminds us about world resources and environmental issues. Random patterns have been baked into mud by an ever thirsty sun. There is a stark beauty and yet awful realisation that nature is at a premium. Water is scarce and precious, this scene man made. A ladder invites us down into the dredger; the situation is not hopeless and we still have the ability to change matters. We alter the world when we dredge the earth.
