Gene editing needs better sales pitch

Health Canada is reportedly likely to treat gene-edited crops differently than genetically modified crops. That would be the right move.

It means the oversight provided by the Canadian Food Inspection Agency would look much like what we see for conventionally bred crops.

This issue is obviously far removed from consumers, but it will certainly affect them.

Genetic modification typically involves artificially inserting genes into the genome of a plant or animal. Gene editing can instantly edit parts of a genome by eliminating, correcting or adding sections to a plant’s DNA.

The yield estimates for wheat and soybeans were neutral to bullish, but these were largely a sideshow when compared with corn.

Gene editing typically doesn’t involve introducing genes from other species, but these techniques allow quite complex control of an organism’s genome. With gene editing, many years of research can be saved by doing adjustments similar to conventional breeding.

Biological and anti-GMO enthusiasts will claim both are the same. They aren’t.

Many countries, including some in Europe, are rewriting regulations for GM seeds to reflect what gene editing can do. This biological compromise is different from unnaturally crossing breeds to create a new plant.

This is welcome news for everyone, including consumers who barely understand the ramifications. Gene editing will impact agriculture and make our farms more efficient.

Consumers will benefit from gene editing without realizing it. By making crop production more efficient, yields can increase while using less land, less water and fewer natural resources. Gene editing can make agriculture even more sustainable.

By tweaking the DNA of plants, crops can adapt faster to climate change, a huge boost for a sector highly vulnerable to Mother Nature’s wrath. Plants can be designed to resist drought, diseases and pathogens, helping farmers in Canada and other parts of the world where farmers are often impoverished by climate change.

Gene editing can also help reduce food waste. Lettuce, mushrooms and tomatoes would have a longer shelf-life because they could ripen later. Supply-chain woes are shortening the shelf-life of many foods we buy at retail. Gene editing can help.

If you have allergies or intolerances, gene editing can also play a role. For example, non-gluten wheat can make bread and pasta edible for those who suffer from celiac disease.

More than three million Canadians say they have at least one food allergy and a million others have food intolerances. Science can make some food less frightening for millions of Canadians.

But gene editing is no panacea for all our ills in food. Fear-mongering groups have already started to express concerns about gene editing. And to a certain extent, these groups are right that more research is needed and that we should move forward with extreme caution. Nothing is absolute or perfect in science, and we need to appreciate the risks involved with gene editing over time.

The other challenge is transparency. Every day, we’re exposed to food products that include GM ingredients without knowing where they are.

More than 75 per cent of food products sold in Canadian grocery stores can contain some GM ingredients but labels make no mention of it.

To get consumers to befriend technologies that make agriculture more efficient and beneficial, the least we can do is let consumers appreciate how farmgate practices benefit them.
