Gillam is a featured expert in this Australian investigative news program examining the secret tactics used by global chemical giant Monsanto to protect its billion-dollar business and its star product, the weed killer, Roundup.
When it was launched four decades ago, Roundup was hailed as a miracle product, a revolutionary herbicide that would transform farming and keep home gardeners happy too. And it came with the promise that it was safe.
Now a landmark US court case has made headlines worldwide, with a jury declaring Roundup was a substantial factor in causing a school ground keeper's terminal cancer and that the company had failed to warn of the risk posed by the product.
The case has lifted the lid on the lengths the company has gone to, over decades, to avoid scrutiny and to silence their critics.
