A while ago I thought about some concept, which should which should allow us, to get rid of all unwanted life.
This is – by becoming incompatible.
Previously I thought that we could do it by changing the language which encodes nucleotide triples into amino acids (be replacing eg tRNA), but it could result in enormous number of problems with gene regulation.
I’ve just found the “safe” way – take mirror reflection!
If we replace left-handed amino acids with right-handed, we would get mirror reflections of natural proteins. Analogically we could get chiral DNA, sugars, etc. on which new enzymes would work perfectly. Finally we would get normally functioning mirror reflection of natural organism, on which natural viruses couldn’t interact. We know, that there is a small violation of such symmetry (P), but it shouldn’t change the biochemistry.
Such organism would have to be feed with reflected food, produced eg by reflected plants, which use to production symmetric (not chiral) molecules and unpolarized light.
In such world natural hostile organisms, if wouldn’t be translated by a terrorist organization, wouldn’t have chance to transform into chiral versions. They could evolve from zero, but we would have many thousands years of peace.
How to make it? We can imagine synthesis of every molecule, such reflected zygote is made of. The problem is to create the correct structure of membranes with specific concentrations … fill it with life… What with actual trends in nano-engineering should become possible in at most 50 years, I think. Then we could slowly transform our ecosystems.
In that way we could get rid of any plagues. But if in such sterile environment, we would have perfect health? Maybe stresses created by small infections can, like small amounts of radiation, have positive long term influence…?
What do You think about this concept?
