Water – as environmentalists are often reminding us – is fast becoming a precious commodity. Now a campaign from a Brazilian group is asking the public to take a very specific step to stop wastage.

The message is simple – urinating in the shower saves water. According to SOS Mata Atlantica, this simple measure could save over 4,000 litres of water annually per household. It’s backed up with a cute ad campaign.

What do you think of the idea? Sensible way of saving water which would otherwise be lost from flushing the loo? Or are you uncomfortable with the idea of peeing in the shower?

What unusual things do you do to help the environment?
