Quiz: Are you Green About Living Green?

What do you know about living a green life? Are you making choices for your lifestyle that are best for the environment?

Making the right green choices may not be as simple as following current knowledge and trends.

As part of The Early Show's week-long series, Planet Early, which celebrates Earth Day on April 22, this quiz is going to test your knowledge. It was provided by Jeffrey Hollender, host of "Big Green Lies" and president of Seventh Generation, a green products company.

Are cloth diapers are better for the environment than disposable diapers?

No. The conventional wisdom is that cloth is better because you are reusing the diapers.

But reusing diapers requires a tremendous amount of energy to heat the water and calls for use of detergent. Disposable diapers are about 30 percent less heavy than they used to be and take up less room in the landfill than they used to. So it actually is a draw.

It also depends on where you live. If you live in an area with a high supply of fresh water (Colorado), it may be worth it, but if you live somewhere far away from the water supply (Los Angeles) it is not worth shipping the water in. If you live in an area where fresh water is a scarce or threatened resource, you might want to pick disposables. (Look for unbleached, chlorine-free varieties.) If you live in a part of the country where shrinking landfill space is at an ever-increasing premium, cloth is probably a better option

Are hybrid cars better for the environment than non-hybrids?

This is a little more complicated. Just to make a hybrid consumes a huge amount of energy. So, most of the people who buy a hybrid won't offset the energy that goes into making it for about five years. Consumers typically look at the product and how it will perform, but you need to factor in the manufacturing of it as well. The best thing to do is, if you already have a car, make sure it is as efficient as possible.

Is tap water as safe as bottled water?

Yes. It is a total myth that bottled water is cleaner. Drinking bottled water creates a ton of garbage because bottles are not recycled and take thousands of years to decompose. Tap water is just as safe - and often safer - than bottled water. The only difference is if you have your own well. The only place you shouldn't drink tap water is on an airplane.

Is air inside our homes dirtier than outside air?

Yes. The air inside is two to five times more polluted, according to the EPA. Just in the state of California alone, the poor quality of indoor air results in $30 billion a year of adverse health effects. We are actively polluting the inside of our homes with cleaning and personal health-care sprays. And, if you move into a new home, you need to be aware of the toxins of new carpet and paints. You need to use products that are clear or unscented.

Is all beef is bad for the planet?

No. We do use tons and tons of corn to get one hamburger; it's an inefficient use of protein.

But a great alternative is grass-fed beef - let them graze wildly. Cows are not meant to consume corn; they are meant to consume grass. And it's a healthier meat. When you let them graze, they have a positive effect on environment because they build up the soil with more carbon dioxide.
