GMOs and genetic engineering are drivers of health and environmental decline – Expert

Genetic engineering is causing human and environmental harm

Physician and educator Dr Zach Bush has delivered a wide-ranging presentation outlining his views on genetically modified organisms, chemical-intensive agriculture and modern genetic engineering technologies, arguing they share a common approach that disrupts natural biological systems and drives long-term harm to human health and the environment.

Speaking from his background in internal medicine, endocrinology and hospice care, Bush traced the origins of GMOs to the 1990s introduction of glyphosate-tolerant crops, describing glyphosate as a powerful antibiotic that interferes with the shikimate pathway used by plants, fungi and bacteria to produce essential amino acids. He said early genetic engineering efforts inserted bacterial genes into crops to overproduce key enzymes so plants could survive heavy herbicide spraying, a process he says bypassed natural regulatory controls through the use of agrobacterium transfer and viral promoters designed to amplify protein production.

Bush told audiences this model rapidly reshaped global agriculture, with herbicide-resistant crops becoming dominant across soy, corn, cotton, canola and sugar beet production, while chemical use increased dramatically. The promised gains in productivity failed to materialise, claiming yields have largely plateaued while input costs rose, pushing farmers into debt and accelerating consolidation into large, industrial-scale operations. As weeds adapted to glyphosate, Bush said additional herbicides such as 2,4-D, dicamba and glufosinate were introduced, with crops genetically engineered to tolerate multiple chemicals at once. These compounds are highly disruptive to soil biology, waterways, surrounding ecosystems and human health, citing their volatility, ability to drift beyond target fields and tendency to persist in the environment and the body.



According to Bush, regulatory systems have allowed this expansion by approving genetically modified seeds and the chemicals used on them through separate pathways, preventing comprehensive assessment of cumulative, long-term or multigenerational effects. He argued this fragmented oversight has enabled widespread environmental contamination and contributed to rising rates of chronic disease, including cancer, metabolic disorders, infertility, neurological conditions and immune dysfunction, which he linked to damage to the human microbiome. Bush said low-level chemical exposure alters gut bacteria, disrupts organ-specific microbiomes and undermines biological resilience across generations through epigenetic effects.

Extending his critique beyond agriculture, Bush drew parallels between GMO technologies and the rapid adoption of mRNA and CRISPR-based genetic engineering in medicine. He described CRISPR as a system that naturally protects organisms from viral threats but is repurposed in biotechnology to cut and insert genetic material directly into genomes, bypassing innate regulatory safeguards. Bush argued that mRNA technologies, including those used in Covid-era gene therapies, market to the public as ‘Covid vaccines’, represent a form of large-scale human genetic intervention, claiming synthetic mRNA instructs cells to produce proteins without the multiple layers of biological control normally present. He said this approach has been deployed without long-term safety data and warned of potential downstream effects that may only become apparent over decades or generations.

Bush also challenged the idea that GMO agriculture “feeds the world,” stating that most genetically modified corn is used for animal feed or ethanol production rather than direct human nutrition, while food insecurity persists in major farming regions. He said chemical agriculture depletes rural economies, damages public health and benefits multinational chemical and pharmaceutical companies, while externalising environmental and medical costs to communities. As an alternative, Bush highlighted regenerative farming systems that reduce chemical inputs, rebuild soil biology and restore water ecosystems, citing examples where farmers reported improved yields and profitability after abandoning GMO seeds and herbicides.

Throughout the presentation, Bush emphasised the interconnectedness of soil health, water systems, microbial diversity and human biology, arguing that modern disease patterns reflect ecological breakdown rather than genetic destiny. He called for a fundamental shift away from chemical farming and reductionist medical models toward approaches that work with natural systems, urging consumers, farmers and industries to rethink how food and health are produced. The presentation characterised current biotechnology practices as a critical turning point, with Bush warning that continued reliance on genetic and chemical manipulation risks accelerating ecological and human health crises unless deeper systemic changes are made.

  1. Unfortunately the paid-off uni-party administrators posing as “leaders” will say something like “we are the only source of truth, the chemicals (and/or “vaccines”) are safe and effective”.

    • We really have to fight tooth and nail against overpaid representatives of chemical companies’ visions of conformity. The lie that science can improve everything is rapidly appearing as a marketing scam, obstructing the work of nature and the due diligence of real innovators.

    • Yep, I remember that too and it corrupted cows milk, causing inflamed infections. This is akin to smug children playing with matches, in an oil refinery. National need to be shown the door.

  2. The evil Tory scum and their cohorts, want to turn us into a island laboratory, for GMO and chemicals via their sleazy Gene Tech Bill. I’ll vote for anyone who opposes this corruption.

  3. Of course, on the other side of the coin, the driver of these innovations is economic. They are all designed to eliminate labour. The bloke in the street says “beaudy. cheaper veges!” – utterly unaware that the savings come directly out of his potential earnings. Within certain parameters, the greater the proportion of productive employment in a well managed economy, the healthier that economy becomes – everyone benefits.
    The ultimate villain is the shift in capitalist ideology from the rational to the fanatical, the identification of wealth (by any means) with “good”.
    By definition, a sustainable economy cannot produce billionaires.
    Simply put:
    “Make usury illegal and immoral again.”
