Roberts adds that she has become more conscious of the environment after having kids.

"My children are perfect, and you think, 'How can I help sustain their state of bliss and progress?' And really beating up the planet the way we have is not going to do that. I drive a biodiesel car. I try to set goals that are achievable and then once we get those down, find some more goals that are achievable and keep going a little bit, as opposed to saying, 'I am going to be completely waste-free in my house' and all this kind of stuff.  It's just a little bit at a time. And if we all did a little bit at a time, it would just be so impactful," she says.

Well said, Julia! Now if only all celebrity moms would get their act together like you did…..we would have a lot less to write about here in this blog.
