This is going to be a tough one. What do i begin with? Well, they are quiet a bunch of inventions I personally wished were never created or even thought of to begin with. Just like someone stated below, the means of induced ''artificial miscarriage'' (abortion) shouldn't have seen the light of day, talk much of taking it's first victim down to hundreds of thousands we've lost to the process. Instead, we should have device more effective ways than what we have already,as well as adhere strictly to it through sustained maintenance. The human mind is surely capable of such a thing.
This might come through as weird and a lot of people am sure wouldn't agree with me as it doesn't quiet fall in the line of inventions, but it is of my personal opinion that governance shouldn't have been put in place...it is to me the mother of all deceitful inventions as many nations practice bad governance. Governance is meant to be a way of rule where norms and actions are structured, maintained, regulated and held accountable. Unfortunately, recent times seems to have deviate on those principles in almost every part of the continents today. Am stating this on behalf of some certain people, groups, in certain places, regions, countries which the system has comlpletely forgotten about and left totally in a miserable state to anguish in sorrows.
People who enjoy physical experiences on the scenery of Burj Al Arab, Eiffel tower, World trade center and some more developed nations might have little no idea where am coming from, but trust me when i say those who have endured the likes of boko haram, taliban and others, those underprivileged who starve on a daily basis as end results of wars and political manipulations, those ones will most definitely back me up on this.
