About Us

Physicians and Scientists for Global Responsibility New Zealand Charitable Trust (NZ Charities no.CC29935) works with qualified researchers and volunteers who work to produce transparent, high quality science information to educate and inform the public.

Initially titled Physicians and Scientists for Responsible Genetics (PSRGNZ), the organisation was established by a group of medical and scientific professionals, who identified potential risks and uncertainty raised by the comparatively new technology of genetic engineering.

An initial concern lay with genetic engineering of crops. Members were concerned about the possible effects these crops could have on the environment and, through the introduction of new foods into the food-chain, the impact on human health.

Early expertise by qualified scientists were required to submit to the 2000/2001 Royal Commission on Genetic Modification, and PSGR presented a number of expert witnesses in this field. Other submissions have subsequently been made as Applications to New Zealand's regulatory authorities.

PSRGNZ operated as a registered Charitable Trust until June 2008 when a name change was made to Physicians and Scientists for Global Responsibility New Zealand Charitable Trust (PSGR) to better address important objectives.

Scientists have recently recognised that the production and release of technologies - as Anthropogenic emissions - are fundamentally under-regulated, and this produces an existential global risk. Our work identifies recurring themes and regulatory processes that limit the capacity for governments and regulators to protect public and environmental health. For example, safety testing and data used in risk assessment for most technologies remains primarily supplied by the industry that seeks approval for the new technologies. Often many important considerations are excluded, such as the formulation of a product, and added issues relating to how the product is deployed, either into the environment or as a food or medical product. We have identified that a major barrier to knowledge is the difficulties public sector (non-industry aligned) scientists face in securing funding for science. Often funding schemes are poorly funded or not in scope, particularly if the science is interdisciplinary. Lawyers and the judiciary struggle with the complex socio-biological relationships, particularly where legal principles such as the Precautionary Principle have been sidelined and downplayed. This places policy-makers who must make decisions in the public interest in difficult positions, as they are required by law to be impartial and act to protect the health of the public, as well as our natural ecosystems. However they lack a deliberation pathway to act precautionarily.

Research into the safety of biotechnology and genetic modification continues. PSGR considers that biotechnology and new gene editing technologies (also referred to as many documents as ‘new breeding technologies’), requires ongoing regulation - transparency - as uncertainty prevails. New technologies scale quickly into the environment. While natural alterations in biology take decades and centuries, biotechnology can be released at global scale in less than 12 months. Transparency (sunlight) and regulation can help to manage this risk. Issues of unforeseen and unintended consequences remain. New technologies positioned as ‘precise’ appear instead, to be imprecise, raising further questions of risk (Latham 2016) (Heinemann et al 2013). Previously considered ‘safe’ traits appear not so safe (Then & Bauer-Panskus 2017).

CASE: BIOLOGY & GMOS

Regulators often keep complex issues at arms length. GMO crops released as field crops, predominantly have contained traits for insecticidal action or express herbicide resistance. These traits are usually ‘stacked’ to manage resistance, and to promote synthetic herbicide use in combination with the plant emitting a naturally produced insecticide. Regulators have not assessed the risk of the end-product as it reaches the public, complete with ongoing regimes of herbicide sprays consumed by the civil society (Latham et al 2017). Herbicide resistant biotechnology crops have resulted in increased rather than decreased pesticide usage, resulting in the production of superweeds. Earlier claimed buffer zones are inadequate to prevent cross-pollination (Hofman et al 2014). Issues such as risk from horizontal gene transfer remains outside risk assessment, yet potentially invasive (promiscuous) volunteer species can spread outside planting zones (Paull 2018) (Tang et al 2018). Questions relating to biopiracy arises when traits, such as drought tolerance which have arisen following decades of cultivation and cross-breeding are slightly altered and patented by a private firm. As more and more pastoral farmers recognise the importance of forage mixtures, might drought tolerant single species outcompete other species, effectively becoming an invasive weed? We also observe the failure to draw attention to issues of regional suitability, which is why farmers might breed one strain of wheat in a different temperate region from another; and the issues of yield returns, for example between herbicide tolerant species and naturally bred hybrids. However cost-benefit analyses have not taken steps to overlay, for example the adverse effect of pesticide spraying regimes, with longer term yield returns.

Biotechnology and gene edited organisms are one technology sector. The biotechnology sector has expanded significantly in the last 3 decades. Media may struggle to adopt a public interest stance, when communicating complex issues of science, ethics and biology. Looking into the future, the cultural and political difficulty governance bodies have with in keeping industry power at arms length and stewarding biotechnology safely, is reflected across a myriad of technologies. With the increasing incidence of cancer and chronic complex health conditions that are increasingly associated with technologies that are persistent, bioaccumulative and/or toxic, there are many opportunities to pivot stewardship of technology to protect public and environmental health.

NEW MEMBERS WELCOME

Members and associate members have provided significant expert scientific advice. We welcome new members with expertise and/or energy, who feel passionate about sharing evidence based, independent science. We also welcome members who might provide insight on how ethical and legal processes might be improved in order to improve deliberation and decision-making across expert communities.

Valued PSGR Past Trustees

Several past members have greatly contributed to PSGR, and their biographies are listed below.

Dr Robert Anderson

Sadly, Robert Anderson (Bob) died on 5 December 2008.

In recognition of his decade of service to PSGR, and to many other organisations, PSGR hosts his public lectures. Other work and lectures can be found on www.connected.gen.nz, sponsored by The Blase Company, Auckland.

Amnesty International Tauranga Moana has established the Robert Anderson Memorial Award presented annually for commitment to Social Justice, Peace and Human Rights in recognition of the Bob's work. See www.connected.gen.nz.

Robert Anderson held a combined honours degree in Physics and Chemistry, and a PhD in Science Education.

Prior to taking his degree, Robert worked at the University of Birmingham, England, as a research technician in the Department of Biochemistry, under Dr John Teal from the University of Cambridge, studying fluorescence of proteins in neutral solution. He also worked under Professor Brian Perry from the University of Cambridge, investigating the actin/myosin relationship in muscle protein.

Robert and his wife, Jean, emigrated to New Zealand in 1968, where Robert taught Chemistry, Physics, Laboratory Technology and Nuclear Medicine at tertiary level.

In retirement, Robert gave public lectures on genetic engineering, other scientific and environmental issues, and peace and social justice, in support of the public’s right to be independently informed. He authored eleven books, including two co-authored with Dr Mike Godfrey, Director of the Bay of Plenty Environmental Health Clinic, Tauranga. He contributed regularly to New Zealand periodicals.

Robert was a Trustee of PSRG from its inception as a Charitable Trust and change of name to PSGR.

In 2010, Amnesty International Tauranga Moana established the Robert Anderson Memorial Award to honour the contribution that its member, Robert (Bob) Anderson, had made to Peace, Human Rights and Social Justice.

Dr John R Clearwater

Researcher and consultant. John Clearwater was a founding member of PSRG in 1998, and one of six initial Trustees. Ill health forced John to relinquish his Trusteeship in 2008. It was with sadness we accepted his resignation. John has consistently made valid contributions and supported PSRG. We will miss his involvement and commitment, and especially his sense of humour. Keep well in the future, John.

Dr John Clearwater has a PhD from the University of Alberta, Edmonton, Canada, and a BSc and MSc from Massey University, Palmerston North, New Zealand. He is the principal scientist at Clearwater Research and Consulting.

From 1975 to 1979, Dr Clearwater carried out ecological research on the sorghum shoot fly at the International Centre of Insect Physiology and Ecology in Nairobi, Kenya.

In 1979, he returned to New Zealand and joined the DSIR, transferring in 1992 to Hort Research.

During his career, Dr Clearwater developed a method of controlling codling moth with pheromones and in 1992 produced the first New Zealand export crop of organic apples with Tony Belcher of Waihi. After failing to convince his managers of the value of this achievement, he resigned and set up a programme of organic apple growing in the Hawkes Bay. This followed the invitation of a local grower, John Bostock, and John Mangan of Freshco. By 2001, this programme had grown to include over 50 growers and five percent of New Zealand’s apple growers. By the 2000/2001 season, the best return was $80/carton of organic Royal gala apples on the US market, compared to $8.25 (loss of $1/carton) for conventional apples. The biological insecticide Bacillus Thuringiensis is a key tool in this activity.

Dr Clearwater provided the pheromone-based monitoring system for the successful programme that eradicated the White-Spotted Tussock Moth from the suburbs of Auckland. The monitoring allowed accurate placement of the biological insecticide B. thuringiensis.

Number of referred publications: 29.

Dr A Neil Macgregor

Sadly, Neil died on 16 September 2009. He had been active in PSRG/PSGR since its inception. Neil brought a wealth of experience to the work he did, dedication, and a great sense of humour. He will be sadly missed.

Neil Macgregor was a biological scientist with primary expertise in soil biology and biochemistry, soil microbial ecology, and microbial genetics. He graduated BSc and MSc from the University of Otago (NZ) in 1961, and PhD from Cornell University (USA) in 1968.

Dr Macgregor held both teaching and/or research positions at Cornell University, the University of Arizona in Tucson, the University of Wisconsin in Madison, the International Atomic Energy Agency (IAEA) in Vienna, the Institut National de la Recherche Agronomique (INRA) in Montpellier, Makerere University in Kampala, Uganda, and Massey University, Palmerston North (Tiritea Campus), New Zealand. From 1991-99 he was an academic member of the University Council of Massey University, and was national Vice President and President of the Association of University Teachers in New Zealand (AUTNZ) from 1985-1989.

Dr Macgregor had relevant research experiences in soil biological processes and land-use systems including biological nitrogen fixation and transformations in both terrestrial and aquatic natural environments, land disposal of rural and urban waste streams, soil and water quality, and the experimental use of reporter genes in soil microbial ecology studies.

Specific research interests included the biological decomposition of herbicides, the role and soil persistence of microbial inoculants in biological nitrogen fixation and sulphur oxidation, biochemical transformations of nitrogen and carbon in soil and aquatic environments, and the use of reporter genes in soil microbial ecology. He had ongoing major interests in soil biology and ecotoxicology, microbial ecology of land-use systems, as well as in the animal health industry, anthropogenic stresses of soil biological activity, and sustainability of land-use systems.

Dr Macgregor authored/co-authored over 70 refereed publications and conference papers. He contributed the chapter ‘Footprints of Genetic Engineering in Agriculture’ to Designer Genes and frequently addressed community groups on the effects of transgenic crops on soil biology, and on further soil research in the organic and vermiculture industries.

He was a Trustee of Physicians and Scientists for Responsible Genetics and Co-Editor of the digital publication, Journal of Organic Systems.

Neil Macgregor was a founder of the Journal for Organic Systems and a tribute to him and his work can be found on http://www.organic-systems.org/journal/Vol_4(1)/pdf/01-03_Neil_Macgregor_Appreciation_Hill.pdf.
