Daniela Ruah: Hi, I'm Daniela Ruah, and you're watching the Mother Nature Network.

Daniela Ruah: Hey there, I'm Daniela Ruah. My advice for being a little bit more eco-friendly is do as much exercise as you can, and walk places instead of driving. And also, take some bags to the supermarket — save plastic, save paper, um, and ... recycle!

Pauley Perrette: Hi, this is Pauley Perrette and my new green tip is that I've been getting permanent straws, because I drink out of straws all the time. So I'm not constantly throwing away a plastic straw every five minutes. I just keep a permanent straw that's made out of, like, really thick material and I wash it out all the time and I'm not throwing away my straws. There's chaos!

Pauley Perrette: This is Pauley Perrette, and you're watching the Mother Nature Network.
