Hi, I'm Hannah Coreman and I graduated

from the Masters Program in Earth Sciences at

Stanford University and I'd like to talk to

you about what the word organic really means.

You know it's hard to be a consumer these days

because there are so many terms in the grocery store.

All natural, multi-grain, and some of these don't

really mean much, but organic means something very specific.

It is a term that's defined and

certified by the government through the U.S Department

of Agriculture.

Now, the term organic doesn't always mean that the

food is healthy, especially if the food is highly processed.

Just because a cookie is organic, it doesn't mean it's any better for us.

But, let's take a minute to look at what organic does mean.

For fruits and vegetables, organic means there are no synthetic pesticides or

fertilizers, no genetically engineered crops and

no sewage sludge used in the production.

Now, pesticides and fertilizers are used to help us to grow

large amounts of food but they have serious environmental and health impacts.

Fertilizers and pesticides are made from fossil fuels and using

them adds greenhouse gases to the environment and increases global warming.

And even though we think of extra nutrients as a good thing,

overusing fertilizers pollutes our waterways, and

harms fish and other marine life.

Overusing pesticides can also be harmful by producing super bugs or

pests who can survive any amount of pesticide killer that you use.

For meat and milk, there's another reason to buy organic.

Because organic meat and milk, come from animals

that didn't receive any unnecessary antibiotics or growth hormones.

The amount of antibiotics we use

on livestock today, can create antibiotic-resistant bacteria

that can make humans really sick in ways that we can't treat.

Growth hormones are allowed in the U.S, but are

banned in the European Union, Canada and other countries.

And lastly, farm workers who are regularly exposed to pesticides can

face big health threats, including poisoning,

cancer, birth defects, and learning disabilities.

Now, this is not meant to scare you away from fruits and vegetables.

It's just to say that if

you can afford it and if you can find it, you

may want to choose organic for any one of these reasons.

There will be no pesticide residues and you'll help save the planet too.
