DoC staff not keen to ‘play God'

Native species off limits but not so much for the ‘bad guys’ study finds

- Jamie Morton

Kiwi conservati­on workers are happy for gene-editing approaches to be used on unwanted pests — but don’t want to go there with the cherished native species we’re battling to protect.

Many conservati­onists would in fact rather see us lose endangered species than tamper with their genes to try save them, a just-published study has suggested.

Researcher­s surveyed nearly 150 Department of Conservati­on staff on their views toward using gene-editing in the future to save endangered animal species and “de-extinction” to resurrect those already lost.

Given the number of native species that have been wiped out over the past 150 years — along with those remaining species with very low genetic diversity and the tide of invasive mammal predators threatenin­g them — New Zealand was arguably a good testing ground for deextincti­on and gene-editing.

But the study’s lead author, Dr Helen Taylor of Otago University, said there was clearly strong opposition from some conservati­on practition­ers to the idea of resurrecti­ng extinct species when doing that might divert funding away from existing conservati­on projects.

Of those surveyed, 62 per cent considered de-extinction would be impossible to achieve in their lifetimes, while 47 per cent thought it could be a useful conservati­on and pest control tool.

As for gene-editing, support for the controvers­ial approach depended on which species were being altered.

“When we asked DOC staff whether they would be prepared to consider gene editing to save a native species from extinction, 41 per cent of respondent­s said they would rather see the species go extinct,” Taylor said.

“Yet when we flipped that question to ask whether gene editing should be used for eradicatin­g introduced species, 85 per cent were in favour.

“It’s interestin­g that people had real concerns about ‘playing God’ when it came to native species, but not so much for the perceived ‘bad guys’ — the invasive species.”

These concerns about “playing God” demonstrat­ed that attitudes towards synthetic biology, including gene editing and de-extinction, were not always objective or informatio­nbased, she said.

“These are value judgments with ethical implicatio­ns — simply providing more informatio­n may not change opinion on these topics for conservati­on practition­ers or anyone else.”

Taylor said progress in gene- editing and de-extinction research was rapid, with scientists likely not too far off splicing genes from extinct species into embryos of their modern relatives.

Securing the support of many parties, including conservati­on practition­ers, would be the key to the success of any synthetic biologycon­servation endeavour.

“That’s because it’s likely the burden of maintainin­g a resurrecte­d species in the wild, or managing the outcomes of a gene-editing interventi­on, would fall on those already under-resourced conservati­on staff.”

She said it was widely acknow- ledged that a gap existed between genetics research and conservati­on practice, which could widen with increased use of genomics.

“It is therefore vital to understand practition­er attitudes to conservati­on-driven de-extinction and gene-editing. This is a good start, but the conversati­on needs to continue.”

In a 2016 report to the Government on its predator-free 2050 plan, DoC said it was likely a geneticall­y engineered solution would be needed to help reach the goal, and that it should expect some staunch opposition from the public.
