Because it takes carbon materials nearly six half-lives, or more than 32,000 years, for their radiocarbon levels to drop by 98%, for all practical purposes we must consider fossil fuels and fossil fuel emissions a non-renewable low radiocarbon resource.
Should low radiocarbon foods be found to offer any significant health benefits, efforts should be made now to capture or sequester as much of the low radiocarbon fossil fuel CO2 emissions as possible for the sake of future generations. Our current practice of irretrievably releasing these emissions directly into the atmosphere not only contributes to global warming but also squanders low radiocarbon CO2 which could otherwise be used to grow safer foods with lower levels of harmful radioactivity.
