Synthetic biology and the conservation of biodiversity

Kent H. Redford March, 2016

First Seminar on Synthetic Biology to Regulatory Decision Takers from Latin

America

I was raised to think that Nature was something obvious and entrancing

Courtesy: P. Coppolillo

It was different from us – the natural world that wasn’t human.

We wanted to conserve it from destruction …

…. by people

Because humans were bad for nature

So to save nature remove humans

Nature would thrive without human interference

Management of nature meant no management

Then the way I understood the world changed dramatically…

Habitat Destruction Invasive Species Climate Change Economic Exploitation

Human Impact is Pervasive

COMMUNITY / ECOSYSTEM

POPULATION/SPECIES

GENES

Affecting all biodiversity Components

Human impact so pervasive that we are now in a new geological epoch

Biodiversity will need to be managed to be saved.

Active Management Work in Latin America 1. Reintroduction of injured giant anteaters:

Argentina 2. Increasing number of eggs w/ macaws:

Guatemala 3. Captive breeding of endangered frogs:

Panama 4. Raising turtle hatchlings: Peru

Informed management decisions made more complicated by climate change

In lieu of the simple dichotomy with which I had been raised …

People bad! Nature good!

We found out we live in a hybrid world

Major Lesson: Saving nature requires management

Conservation Action – in the Past

Conservation Action in the Future

What will happen in this novel operating space?

Genome Editing – CRISPR Technologies

a novel technique of gene editing (silencing, enhancing or changing specific genes)

SPECIES TRAIT TARGETED w/ SYNBIO TECHNOLOGIES Pigs swine flu; fattened w/ less food; miniaturized (pets) suitable for xenotransplants*; resist flu* Chickens produce only females* Dogs more muscles Goats more meat; longer hair Cattle expression of horns; only males*; resist sleeping sickness* Mice sickle-cell anemia; muscular dystrophy; cystic fibrosis; cataracts; receptors that H.I.V. uses to access human cells Mosquitos malaria transmission Diamondback Moths only females Wheat powdery mildew Rice more starch & less methane *In progress

(Harmon 2015 NYT; Specter 2015 New Yorker)

Things are happening across a broad – and rapidly changing front:

Very little consideration in synthetic biology of the issues of importance to conservation or of the impact on the natural world

How will synthetic biology and conservationshape the future of nature?

Enhance capacity to restore degraded ecosystems

Land degradation costs an estimated US$40 billion annually worldwide, without taking into account hidden costs of increased fertilizer use, loss of biodiversity and loss of unique landscapes (http://www.fao.org/nr/land/degradation/en/)

Significant Concerns

Synthetic life will evolve

http://www.economist.com/images/20060902/D3506SB1.jpg

CRISPR-Cas-9 modified animals vs

Animals altered with other Genetically modified technologies

Altering of native genome with itself vs

Altering native genome with genome of other species

So what might this mean for conservation?

We should envision a new field: “Synthetic biology conservation stewardship” that might engage in:

Synthetic biology is inevitable:

IRRI working to transform rice from inefficient C3 photosynthesis to C4 photosynthesis (as in corn, sugarcane, and sorghum). That switch has been made in plants 60 independent times by evolution. Three billion people depend on rice for survival. A change from C3 to C4 would: 1) generate a 50% greater yield, 2) use half the water, 3) need far less fertilizer, 4) greater resilience to climate change?

Big changes coming in Agriculture too

If this happened, how many other things would change?

To respond to such major changes conservation needs to engage with the Synthetic Biology community across the full range of things they are doing that influence the natural world

What will conservation want in a world of synthetic biology?

• Persistence of evolution – autonomous in some form

• More, better managed, “wild” areas and species • An elevated sense of the long-term and of

precaution in interventions and risk management

• A sense of humility in management • Our diverse perspectives consulted and

incorporated • As much of “nature” saved as possible

Frame message with Counterfactuals The difference between what we can observe and what we would have observed had we done conservation differently.

In the new poll, 71 percent of Americans said that they're excited about the possibility that DNA research could bring major scientific and medical breakthroughs. But 44 percent said they worry that DNA research involves unforeseen dangers. Thirty-three percent of Americans said they were both excited and worried.

Poll Shows We Want Those DNA Breakthroughs But Worry Scientists May

Engaging the Public Early and Often …

The advantage of leading with conservation applications: Members of the public show enthusiasm for synthetic biology applications when those applications are developed to address societal, medical, and sustainability needs, whereas engineering biology is seen as a potential concern if this research is done without investigations of its potential risks and long-term implications. Members of the public also support funding for research that leads to applications that actually meet social and sustainability goals. Pauwels (2013) BioScience

Humans and nature have become co-mingled

Making it hard to know what conservation is about

Unfortunately, current conservation debates are important but limited by being:

circumscribed by the past not informed by the novelty of the emerging future not alert to the perils and possibilities of this future not fit for purpose – our responsibility to the natural world.
