An environmental campaign in Brasil is encouraging people to pee in the shower to reduce water usage. According to their calculations, cutting down on one flush per day can cut your yearly water usage by 4380 litres. In Sao Paolo they hope to save up to 1500 litres of water per second!

unfortunately am not living in Brazil.. )) but i would give it a try .... -))

I reckon you can "do your bit for the planet" no matter where in the world you are.
