10 things you may not know about GMO

Whether you like it or not, you probably have an opinion on GMO. But how much do you actually know about it? Find out which knowledge nuggets might have gone under your radar!

1. GMO - the process

We know the term, GMO, and know it has something to do with genetics, right? But what do we actually know about the process itself? The exact details are as follows *drum roll*. GMO stands for genetically modified organism and it is a bioengineering technique.1 It extracts the foreign DNA of one organism and inserts it artificially into the DNA of a completely different organism altogether. And they don’t even need to be of the same species.2 If it has genes, it’s possible. For a step by step guide on the process, read on here.

2. GMO has been around for ages

As crazy as it sounds, a lot of what we already eat is genetically modified - we might just not know it. For centuries, we’ve been Nature’s matchmaker through farming, and in the process, we’ve played a hand in genetically modifying a lot of what we’d define as normal’ today.3 For example, a wild carrot looks more like a potato that’s been on a torture rack than any carrot we’ve ever seen (the poor things). 

3. GMOs can actually help out small farmers

A farmer’s job can be pretty tough sometimes. For a farmer to bring home the bacon (asides from the pigs on the farm of course) everything depends on how mean Nature is feeling that year. Crop yields can plummet if there are bad weather conditions, which can be catastrophic for a small farmer.4 Inbuilt resistance in GMOs, however, can really help fight this, and when your harvest is already small, every little helps!

4. GMOs aren’t just in your food

Cotton can also be ‘GMO’d’, and as a result a whole tonne of other everyday items have GMO ingredients in them.5 Sheets, towels, clothes, you name it, if it’s cotton, GMO could be in there too. It doesn’t stop at cotton though. GMO can be found in a bunch of other products. Alcohol can be made from GM corn and soy, so as a result GM can be found in toiletries, hand sanitiser, ink, gasoline - the list is as surprising and diverse as it comes.

5. Some countries really don’t like GMO. Seriously.

In 2015, 38 countries had a ban on the cultivation of GM crop,6 and with new laws and technologies always developing, such regulation is constantly under review. This distrust can be traced back to uncertainty. As mentioned earlier, even our definition of GMO can vary, so it can all become quite messy. Even scientists are divided in their opinions and do not wish to assert GMO as definitively safe or unsafe.7 The official scientific consensus may back GM,8 but people like certainty across the board when it comes to matters this important, and this is where division can arise.

6. The US was the first country to invent GMO crops

Their investment goes further, with 93% of soy and 88% of corn in the US being GM.9 That’s a big number for two big products. Corn is used for thickening food such as porridge and soup, sweetening thousands of food products and feeding farm animals.10 Soy also feeds farms, is a big source of food oil and can actually be used as a biofuel.11 To top it off, between 60-70% of all processed food in US grocery stores have some form of GMO ingredients in them.12 Phew.

7. GMO is also known as… Frankenfoods

Get it? Because it’s the Frankenstein of foods?13 There are actually multiple names GMO goes by, so it’s good to know the list in case you ever want to impress your friends at a party (I go to some fun parties). There’s transgenic organisms, Frankenfoods and living modified organisms.14 You’re welcome.

8. GMO can allow for fewer pesticides to be used

Pesticides are used to get rid of those pesky critters eating all our grub. But one form they can come in is damaging chemicals, which the less we use the better. One use of GM is to do the job of pesticides for them. For example, some crops have been given the Bt gene, which produces Bt bacteria - harmless to the plant, but deadly to the specific insects who enjoy a nibble of that crop.15 These crops have turned into some tough cookies, I mean vegetables.

9. There are multiple generations of GMOs

GMOs have been around since the early 90s,16 and in plant years, that’s ages (I’m sure there’s a wizened old vegetable out there mumbling, ‘Back in my day…’). As a result, enough time has passed for there to be multiple generations for the reasoning behind GM.17 The first centred around the farmer and delivering better yields and reducing costs. The second was consumer centric, better taste and shelf life. Only time will tell what the next will be…

10. GMO may one day be outmuscled by CRISPR

There’s a new kid on the genetic block, and its name is CRISPR. It edits genes that already exist in an organism rather than inserting new foreign ones. It’s cheaper, it’s easier, and it may end up being the future of genetic engineering.18 Just don’t tell GMO I said that OK?
