By now,
Everyone's seen the Info graphic about the destruction resulting from the
battle in Metropolis
You know
Now that is pretty staggering, but as an alternative perspective
what about THIS :
Superman fails to stop Zod and Kryptonians from terraforming Earth
(or Superman destroys world engine but fails to defeat Zod , who
then exterminates humanity)
confirmed dead : 7,000,000,000 + (entire human population, and probably
entire animal/plant population)
impact comparable to : Global Thermonuclear war
economic cost: $195 quadrillion US dollars.
( $ 195, 000,000,000,000,000, look it up on Wikipedia)
overall impact: Total destruction of absolutely everthing.
What's the point ? Lesser of two evils baby !
