  • Great crop. Hashtag harvest time.

  • Ohhey! I’m Jake, a GMO seed.

  • I’m here to tell you about the life of a seed.

  • So let’s start with the basics.

  • Some people think that GMOs are created after harvest,

  • by injecting chemicals into foods,

  • or are added artificial ingredients.

  • But that’s not the case.

  • The truth is, GMOs - in agriculture - are seeds.

  • So what is a “GMO seed?”

  • Well, to understand that let’s talk about the history of farming and plant breeding.

  • Farmers began breeding plants for desirable traits

  • when farming first started.

  • Although early farmers didn’t know it, they were modifying the genetics of plants

  • by continually breeding different plants together,

  • harvesting the seeds and selecting the best performing plants to grow again the following year.

  • Over the years, seed breeders and scientists built on this knowledge.

  • And it has resulted in some pretty dramatic changes.

  • Check it out.

  • These techniques gave us all sorts of new foods,

  • including conventional and organic.

  • One of the new techniques seed breeders and scientists introduced

  • was genetic engineering.

  • With this, were not making dramatic changes,

  • were making very specific changes to a seed’s DNA

  • involving one or a few genes

  • to produce plants with specific traits like the ability to fight disease, bugs or weeds.

  • The crops grown from these seeds are referred to asGMOs”.

  • GMO seedslike me - are unique because we go through a lot of safety testing

  • and are reviewed by up to three different government agencies in the U.S. before we can get planted.

  • Okay, back to the basics.

  • So farmers can choose what kind of seeds they want to use.

  • Some plants are attacked by natural predators like worms and bugs,

  • so farmers might choose GMO seeds that protect them specifically against those pests.

  • This is my friend after he was attacked by a bug.

  • Sorry, dude.

  • But GMO corn plants - grown from GMO seeds like me -

  • are protected, so we don’t end up like my friend over here.

  • This protection also helps reduce crop damagelike this

  • and the need for extra pesticide applications.

  • So then the farmers plant us.

  • And then, we grow into plants.

  • Look at that. Gorgeous.

  • No matter which type of seed the farmer chooses,

  • the food produced from them has the same proteins and nutritional makeup.

  • We were just developed differently.

  • When the crops are harvested, they can be used in a variety of ways

  • like the food you eat,

  • plant-based products,

  • food for animals,

  • and over 12,000 other uses.

  • So that’s itnow you know the life of a seed!

  • See you later!

Great crop. Hashtag harvest time.
