Cloning doesn't work. It's lengthy, complicated and expensive. Not to mention the defects, the chances of miscarriage by the surrogate mother, stagnation of the gene pool. Sex is quite simply the best way to reproduce. It's slow enough to allow prepartaion for the child as well as maintain manageable population levels (in theory) and is easy enough so that if all but a few hundred people were wiped out, the world could be repopulated.
Human Race: This is put out by the church and is quite frankly racist. They say that tampering with the genome to improve people is immoral and the result is not a true human but a perversion of science. Bull****. Culture, ideology and fundamental ways of life are what make up the human race. Making people faster, stronger, smarter and more resistant to disease may be interfering with nature but it's no more interfering than spray crops and the results are far more beneficial to the survival of the human race. For it is not our genes that make us human but our beliefs and history, the church and activist groups either don't seem the picture, see inciting public outrage as a way to gain power or are simply so stupid that they do not understand a simple fact. The human genome changes naturally. You can wipe out all the genetically altered people and have a 'pure' human race but if that alteration is in our dna then eventually it will surface again. Eg, If there were super-smart chimp and you killed them, eventually more would be born and the smart ones would survive, but if you kill the normal chimps then the smart ones survive anyway. What I'm trying to say is that everything evolves, no matter how hard you fight it and the human race will not always be the same as we are now so speeding up nature is not wrong. But still, cloning is inefficient.
I seem to have lost my point somewhere along the way. Meh.
