Clonning is not good....
Takes away natural variation...
So if a virus is able to kill one cow... it will kill the whole lot...
Nil would be immune caz they are copies of each other.....
the "immune" system will still exit
. Each animal under different environment like Sun, Cold, Hot, etc, shows different genetic traits as these animals are kept on different diet and in different environments.
Plus, if you've ever studied Biology beyond basic college courses, you'l fund out that germs (Viruses, Bacteria, Amoeba, etc), mutate in different conditions and environments too. So humans, animals and germs, all evolve per their environment. Its not true that one germ can kill all animals, etc.
Here comes a virus world is not prepare for. Cloning leads to mutation of living cell. even poltary chicken is dangerous as it leads to number of diseases. Eating cloned animals will lead to mutate our body to a way we dont know. every mutated animal will have different disease which will lead to numerous new diseases in human body .
It takes time for scientist to find cure of new diseases and making mass production of that cure takes minimum 3-4 months ( after finding cure). this will lead to millions of deaths
Do you have background in Cloning? They aren't creating a "new" species altogether. They are just creating another set through Cloning. Like Test Tube babies if you will. Only, with a more mature scientific process involved.
I know two test tube girls that are now 17 and 16. Perfectly healthy and normal!! I am not saying clone humans too, but just giving out an example of a friend who couldn't have a baby for ten years, and they went to Test Tube. And today, they are glad they did!!
Cloning has serious benefits for humans if done correctly. This can cure Cancer, Heart Disease (scar tissue, etc), Brain Tumors, and missing or damaged organs. Call it a 3D printing of a live body overtime.
