Genetic Greatness

The sciences behind genetic engineering can be exceedingly complex, but the benefits we can pull from studying our DNA are definitely worth the effort.  When we look at how evolution works, we see that a species can develop specific changes over several generations if the changes made are beneficial to the species, but if we were to find out how our own genome works we could supercharge our evolutionary speed, developing resistance or driving out genetic diseases.  Alternatively we could also focus on external forces, and while we would develop resistance to disease through years of exposure, we could combat entire strains with new medicine tailor made to fight them.  

Another use for gene manipulation is in food, and although we already do we could be expand on what we do in that field, and lower the potential negative consequences of manipulating our food on a genetic level.  We can create new vegetables able to survive in harsher climates, opening up possibilities for increased production or distribution of food around the world.  All of these things may happen, if given enough time for the natural processes to kick in, but if we can create all of these amazing things, why would we not try to do it as fast as possible?
