Harness Genetic Technology Now to Prevent Upcoming Food Crisis

There are two major problems with the global food system. First, hundreds of millions of people cannot afford enough nutritious food to stay healthy. Second, it’s incredibly destructive. We’re still destroying rainforests to make way for ranches, both conventional and organic farms produce all kinds of pollutants, and our food system produces more than a third of greenhouse gases. I’m letting you do it.

Things could get even worse if global temperatures rise above 1.5 °C (see 2024 expected to be first year to surpass 1.5 °C warming threshold). But there’s a lot we can do, from eating less meat to reducing food waste (see “Is the climate food crisis even worse than we imagined?”). The amazing advances in genetic technology in recent years have greatly expanded the scope for improving the plants and animals that feed us. We can make them more nutritious and healthier, better able to cope with changing conditions and less susceptible to the diseases that will become more prevalent as the world warms. It should also be possible to produce plants that require less fertilizer and capture more of the sun’s energy.

The benefits from all this will be immense. We get more food from less land, lower prices, reduce greenhouse gas emissions and make it less likely that viruses such as H5N1 bird flu will cause new pandemics.

It is therefore surprising that most countries do not invest heavily in crop improvement. While there is some private investment, these companies are unlikely to make their technology freely available and adoption has been slow.

Opposition to genetically modified (GM) crops also binds us to the idea that more “natural” agricultural methods are better, as approval is difficult and expensive.

This situation is starting to change, with many countries making it easier to bring gene-edited crops and animals to market, but we need more action, and faster action.

The idea that organic food is good for the planet and genetically modified food is bad for the planet is a false narrative that hides a much more unpleasant reality. This means that continuing as is will only lead to more destruction and more hunger.
