Many scientists warn of Genetic crop health issues and chemical dependance. NZ needs to say no to the Gene Technology an Glyphosate increase bills.
The New Zealand Government is promoting its Gene Technology Bill as an “update to match science and technology.” In reality, this law would deregulate genetically engineered (GE) crops in ways that ignore well-documented harms and global experience. Independent research and international case studies demonstrate that GE crops are not only failing to deliver safety promises but are also directly linked to ecological damage, health risks, and costly regulatory failures. An example of just one study's conclusion following chronic ultra-low dose Roundup exposure: "Our results suggest that chronic exposure to a GBH in an established laboratory animal toxicity model system at an ultra-low, environmental dose can result in liver and kidney damage with potential significant health implications for animal and human populations."
Glyphosate accumulates in human tissues, disrupts gut health and hormones, impairs cognition, and increase the risk of cancers such as non-Hodgkin lymphoma. NZ.
Economic and Sectoral Risks
There are economic risks: The Sustainable Business Council's members collectively represent NZ$169 billion in annual turnover.
These Bills Could Threaten Key Sectors:
If NZ raises glyphosate limits and weakens genetic safety laws, these risks including cancer, neurological, and hormonal impacts will increase, not decrease.
