RE-DESIGNING LIFE!
THE PROMISE AND PERILS OF SYNTHETIC BIOLOGY
For the past four billion years [THAT’S EVOLUTION TALK - Keith Hunt] or so the only way for life on Earth to produce a sequence of DNA—a gene—was by copying a sequence it already had to hand. Sometimes the gene would be damaged or scrambled, the copying imperfect or undertaken repeatedly. From that raw material arose the glories of natural selection. But beneath it all, gene begat gene.
That is no longer true. Now genes can be written from scratch and edited repeatedly, like text in a word processor. The ability to engineer living things which this provides represents a fundamental change in the way humans interact with the planet's life. It permits the manufacture of all manner of things which used to be hard, even impossible, to make: pharmaceuticals, fuels, fabrics, foods and fragrances can all be built molecule by molecule. What cells do and what they can become is engineerable, too. Immune cells can be told to follow doctors' orders; stem cells better coaxed to turn into new tissues; fertilised eggs programmed to grow into creatures quite unlike their parents.
The earliest stages of such "synthetic biology" are already changing many industrial processes, transforming medicine and beginning to reach into the consumer world. Progress may be slow, but with the help of new tools and a big dollop of machine learning, biological manufacturing could eventually yield truly cornucopian technologies. Buildings may be grown from synthetic wood or coral. Mammoths produced from engineered elephant cells may yet stride across Siberia.
The scale of the potential changes seems hard to imagine. But look back through history, and humanity's relations with the living world have seen three great transformations:
1. the exploitation of fossil fuels, t
2. The globalisation of the world's ecosystems after the European conquest of the Americas;
3. and the domestication of crops and animals at the dawn of agriculture.
All brought prosperity and progress, but with damaging side-effects. Synthetic biology promises similar transformation. To harness the promise and minimise the peril, it pays to learn the lessons of the past.
The new biology calls all in doubt
Start with the most recent of these previous shifts.
Fossil fuels have enabled humans to drive remarkable economic expansion in the present using biological productivity from ages past, stored away in coal and oil. But much wilderness has been lost, and carbon atoms which last saw the atmosphere hundreds of millions of years ago have strengthened the planet's greenhouse effect to a degree that may prove catastrophic.
Here, synthetic biology can do good. It is already being used to replace some products made from petrochemicals; in time it could replace some fuels, too.
This week Burger King introduced into some of its restaurants a beefless Whopper that gets its meatiness from an engineered plant protein; such innovations could greatly ease a shift to less environmentally taxing diets. They could also be used to do more with less. Plants and their soil microbes could produce their own fertilisers and pesticides, ruminants less greenhouse gas—though to ensure that synthetic biology yields such laudable environmental goals will take public policy as well as the cues of the market.
The second example of biological change sweeping the world is the Columbian exchange, in which the 16th century's newly global network of trade shuffled together the creatures of the New World and the Old. Horses, cattle and cotton were introduced to the Americas; maize, potatoes, chilli and tobacco to Europe, Africa and Asia. The ecosystems in which humans live became globalised as never before, providing more productive agriculture all round, richer diets for many. But there were also disastrous consequences. Measles, smallpox and other pathogens ran through the New World like a forest fire, claiming tens of millions of lives. The Europeans weaponised this catastrophe, conquering lands depleted and disordered by disease.
Synthetic biology could create such weapons by design:
pathogens designed to weaken, to incapacitate or to kill, and perhaps also to limit themselves to particular types of target. There is real cause for concern here—but not for immediate alarm. For such weaponisation would, like the rest of cutting-edge synthetic biology, take highly skilled teams with significant resources. And armies already have lots of ways to flatten cities and kill people in large numbers. When it comes to mass destruction, a disease is a poor substitute for a nuke. What's more, today's synthetic-biology community lives up to ideals of openness and public service better than many older fields. Maintained and nurtured, that culture should serve as a powerful immune system against rogue elements.
[THE BOOK OF REVELATION, CHAPTER 9, TALKS ABOUT SPACE-AGE TECHNOLOGY WILL KINDA PARALYZE PEOPLE BUT NOT KILL, THOUGH THOSE UNDER ITS SPELL WILL WISH THEY WERE DEAD - Keith Hunt]
The earliest biological transformation—domestication—produced what was hitherto the biggest change in how humans lived their lives. Haphazardly, then purposefully, humans bred cereals to be more bountiful, livestock to be more docile, dogs more obedient and cats more companionable (the last a partial success, at best). This allowed new densities of settlement and new forms of social organisation: the market, the city, the state. Humans domesticated themselves as well as their crops and animals, creating space for the drudgery of subsistence agriculture and oppressive political hierarchies.
Synthetic biology will have a similar cascading effect, transforming human relationships with each other and, potentially, their own biological nature.
The ability to reprogram the embryo is, rightly, the site of most of today's ethical concerns.
In future, they may extend further; what should one make of people with the upper-body strength of gorillas, or minds impervious to sorrow?
How humans may choose to change themselves biologically is hard to say; that some choices will be controversial is not.
Which leads to the main way in which this transformation differs from the three that came before. Their significance was discovered only in retrospect. This time, there will be foresight. It will not be perfect: there will certainly be unanticipated effects. But synthetic biology will be driven by the pursuit of goals, both anticipated and desired. It will challenge the human capacity for wisdom and foresight. It might defeat it. But carefully nurtured, it might also help expand it. ■
THERE WAS AN AGE IN MAN’S HISTORY ON EARTH THAT REACHED THE SAME LEVEL OF ANTICIPATION.
THE BIBLE GIVES ONLY A VERY SMALL AMOUNT OF DETAIL ABOUT THAT AGE.
IT WAS AN AGE AFTER THE TIME OF NOAH AND THE FLOOD OF HIS DAY.
THERE ARE TWO BOOKS ON THIS WEBSITE THAT MAY HELP EXPOUND THAT AGE, TO SHOW US THE GREAT ADVANCEMENTS MADE. THOSE TWO BOOKS ARE UPLOADED FOR YOU AT THE BOTTOM OF MY “HISTORY” SECTION—— SECRETS OF LOST RACES AND TREASURES OF LOST RACES.
ALL THAT THE BIBLE GIVES US IS:
“AND THE LORD SAID, BEHOLD, THE PEOPLE IS ONE, AND THEY HAVE ALL ONE LANGUAGE: AND THIS THEY BEGIN TO DO; NOW NOTHING WILL BE RESTRAINED FROM THEM, WHICH THEY HAVE IMAGINED TO DO. GO TO, LET US GO DOWN, AND THERE CONFOUND THEIR LANGUAGE, THAT THEY MAY NOT UNDERSTAND ONE ANOTHER’S SPEECH. SO THE LORD SCATTERED THEM……” [GENESIS 11: 6-8].
ARE YOU SEEING THE SIGNIFICANCE OF THE WORDS YOU HAVE READ?
THEY WERE AT THE POINT OF NOTHING WILL BE RESTRAINED FROM THEM WHICH THEY IMAGINED TO DO!
THEY WERE SCATTERED, THEY HAD DIFFERENT LANGUAGES!
IT HAS TAKEN TENS OF THOUSANDS OF YEARS [YES THE IDEA OF MAN BEING ONLY 6,000 YEARS ON EARTH IS A THEOLOGY FROM PLANET PLUTO] TO GET THE NATIONS INTO HAVING ONE LANGUAGE AGAIN—— THE ENGLISH LANGUAGE IS NOW SPOKEN BY ALL THE IMPORTANT NATIONS OF THE EARTH.
THE AGE GONE BY HERE SPOKEN ABOUT IN GENESIS 11, WAS MOVING WAY WAY TOO FAST FOR THE LORD TO WORK HIS WORK FOR HUMAN KIND; IT NEEDED TO BE SLOWED DOWN DRASTICALLY. AND SO GOD DID SLOW IT DOWN, BY DIFFERENT LANGUAGES AND SCATTERING THE PEOPLE.
WE ARE ON THE DOORSTEP ONCE MORE OF THAT IN GENESIS 11.
WE ARE ONLY JUST STARTING TO STEP ON THAT DOOR STEP, OUR FEET ARE ONLY JUST COMING DOWN ON THAT DOOR STEP, THAT WILL LEAD INTO THE HOUSE OF NOTHING BEING RESTRAINED THAT THEY HAVE IMAGINED TO DO.
IT WILL PROBABLY BE ANOTHER 10 YEARS BEFORE WE ARE OVER THE DOOR STEP AND BEGINNING TO MOVE INTO THAT HOUSE.
BUT IT IS A SIGN, ONE MORE SIGN TO WATCH, TOWARDS THE TIME WHEN ALL PROPHECIES OF THE BIBLE MUST COME TO PASS [LUKE 21: 22].
THERE ARE OTHER SIGNS TO WATCH FOR, AS I HAVE MADE CLEAR FOR YOU, IN EXPOUNDING ALL THE PROPHETIC BOOKS OF THE BIBLE UNDER “PROPHECY” ON THIS WEBSITE.
