Water is life-giving. It’s consistent – in how it flows, fills the space it enters. But water is also fluid, changeable. Abundant in some places, absent in others. It is easy to be casual with water when it springs readily with the turn of the tap. The emptying reservoir lies unseen.
Water is local. The drops we thriftily save will not, then, be available to people in drought-ridden East Africa. That’s not how water works. But it doesn’t mean we should be wasteful with it. The water from our taps has already been through the energy-intensive treatment process to make it safe for us to drink. It seems a shame, after all that, to pour it all over our unfussy vegetable plots.
