Cate has planted timers all over her house so that water isn't wasted.
They quote her as apparently saying: "I actually have little races with myself, thinking, 'Oh no, I'm not washing my hair,' – I only need to have a two-minute shower."
Interesting.
Of the timers, she said: "I went to a website and my husband was laughing at me because a box arrived with thirty timers, and I thought, 'Excellent stocking fillers.'"
Cate was said to have visited Lake Samsonvale, near Brisbane, Australia, to see the effects of a crippling drought.
She apparently went on to say: "I'm extremely concerned about climate change as a mother, because I want to ensure for my children a very safe and sustainable future.
"It's great to see my children engaged in these things, like when you put the water on when you put the toothbrush under the tap, you turn if off the minute you take it out and you don't let the water run."
