How do you feel about genetically modified food?

It’s a question that can prompt some very passionate responses and a whole lot of debate: some argue it could end world hunger; others think the risks are too great.

It’s powerful technology. Scientists can use a range of modern molecular technologies to make crops more productive or more nutritious and better for gut health. Farmers can grow crops that can better withstand harsh environmental conditions, such as drought or salty (saline) soils, or reduce the use of pesticides and herbicides.

And yet, despite the potentially immense benefits, some people are strongly opposed to any kind of genetic modification, arguing that it might be harmful to human health or the environment, or pointing to ethical concerns. Decades of scientific studies have provided plenty of evidence in response to these concerns.

But before we can fully delve into some of the conversations surrounding genetic modification, we need to understand the fundamental science behind what’s involved.
