As we all know Scar overthrew his brother in a coup and implemented immense social changes. For the first time the hyenas were given equal rights to the lions. However at the end of the movie we saw Scar's regime in ruins with a famine looming.
A few reasons for this could be either that the famine was totally unrelated to Scar's reforms and was simply a natural disaster. More likely however is that his reforms led directly to the subsequent famine. He promised the hyenas the same amount of food as the lions received under the old regime. However supplies were not increased, only demand. That is the most obvious reason for the looming famine. Another possibility is that the lions purposely over-hunted in an attempt to sabotage Scar's regime or just as an act of protest against the reforms.
Could this have been avoided? I say yes. With a strict regiment of rationing for both lions and hyenas the food supplies could have been sustained. Population controls would have had to be put in place as well to prevent an explosion of predators that would unbalance the ecosystem.
What do you all think was the reason for Scar's reforms failing? Was the famine avoidable or unavoidable? Do you think his ideas may have worked if implemented by somebody more sincere?
