The 'House' star feels it is important that her children - Otis, four, and Daisy, 23 months, who she shares with her partner Jason Sudeikis - know how lucky they are.

She said: "[I tell them] that they won the life lottery. Everything they have access to is privileged, so they have a responsibility to conserve resources and to be kind, embrace gender equality and understand the value of their education. If we can raise a generation that thinks that way, I really think the world will improve."

And Olivia is starting by making tiny changes to her kids' routines.

She told People magazine: "I beg my son to turn off the water when he brushes his teeth. He doesn't understand - like, 'Every time I turn on the tap there's water.' I have to explain to him how limited the resource is, and that opens the door for broader conversations."

Meanwhile, the 34-year-old actress previously confessed she wants her daughter to feel "extraordinary and "recognise her specialness".

She said: "We had a party. There was music, there was dancing, and it's wonderful to see when your child is old enough to recognise their specialness. To give them a special day allows them to feel extraordinary, which they are, and I want her to feel that way as much as possible ... I think about my relationship with my own mother, and I see Daisy, and I am astonished by her every day. I want to raise her to have such a strong foundation that she can handle anything. I won't be able to protect her from everything, but I can give her the tools to fight for herself."
