Ashley Argota: Hey, I'm Ashley Argota and you're watching the Mother Nature Network.
Cheryl Hines: I'm Cheryl Hines. I'm here at the Camp Ronald McDonald Festival and I'm dressed as Medusa. I recycled this costume from last year because, you know? I worked pretty hard on it! So why not use it again and again and again and again? Or pass it on to your friend. Swap!
Nolan Gould: Hey, I'm Nolan Gould from "Modern Family." I'm here at Camp Ronald McDonald and one way that I help make the environment cleaner is by conserving water. By taking shorter showers and by turning off the water while I'm brushing my teeth.
Ryan Ochoa: Hey, what's up, I'm Ryan Ochoa here at the Camp Ronald McDonald Halloween Carnival. And here's one MNN green thing: I think everyone today should plant at least one plant in their neighborhood. Just one. That's good.
Madison Pettis: Hey, I'm Madison Pettis. I'm here at Camp Ronald McDonald's Halloween Carnival. I have a new show called "Life with Boys" — make sure you check it out. And a green tip? I'd say, this is what I always do, I always turn off the water when I'm brushing my teeth. It's really simple and it doesn't take any effort or anything. So make sure you do that.
Nathan Kress: What's up guys, Nathan Kress here at the Ronald McDonald Carnival. We're talking about green tips and the one that I have for you and the one that I try to stick to is: watch your mileage. For you new drivers out there. I know it's cool, you have a car and you like going all fast and everything, but it ruins your gas mileage. So keep a track on it. Use your little computer. All the new cars have that now. You have no excuse.
Marcia Gay Harden: Hey, Marcia Gay Harden. My green tip is: get rid of bottled water. You can use Brita filters in the home, businesses can do it, all companies can do it. You don't need bottled water, too much plastic and you don't know where it's been, if it's been heated up or cooled down, lots of bad things, so get rid of bottled water.
Emily Alyn Lind: Hi, my name is Emily Alyn Lind. My green tip of the day is definitely recycle and always volunteer time to pick up litter on the beach.
Cassie Scerbo: Hey guys, this is Cassie Scerbo from ABC Family's "Make It or Break It" and my green tip for you guys is very simple: I support recycling and ting the water when you're brushing your teeth because I know we all leave the water on sometimes I've even in the past done it where — I'll leave the water on, I'll go do something else, I'll forget it's on. So just simple things like that, like recycling and ... shutting off that water.
Josie Loren: Hi, my name's Josie Loren and my green tip of the day is buy a water bottle so that you don't have to always buy plastic water bottles and throw them away.
Sterling Beaumon: My green tip of the day would definitely be to turn off lights as you leave the room because that can save a lot of energy and also save you money, as well.
Camryn Manheim: Hi, this is Camryn Manheim. And my favorite green tip is: instead of using your air conditioner, wet a sheet and put it on top of you with a fan. It's so great, it causes — it gives you much less of a carbon footprint and you're still cool.
Spencer Boldman: Hey, I'm Spencer Boldman here at the Ronald McDonald Halloween Carnival and my green tip of the day is to make sure that you save the water. When you turn the sink on in the morning to brush your teeth, and stuff like that, make sure you turn it off whiel you're doing it.
Allstar Weekend: Hey guys, we're Allstar Weekend and our green tip of the day is to recycle. Recycle bottles, cans, plastic — anything you got. And glass. Everything! Bruce Springsteen says yes.
Ashley Argota: Hey Mother Nature Network, it's Ashley Argota from "Bucket & Skinner's Epic Adventures." My green tip of the day would be to recycle and also to save your water bottle throughout the day and keep refilling it with water throughout the day so you don't waste the plastic.
