Answer:
slavery
Explanation:
the North wanted freedom and the south wanted slavery.
Confederate general Robert E. Lee hoped for the destruction of the Union Army and subsequently Lincoln's surrender.
Lee knew he was a superior field commander and had greatly superior team of generals working for him at Gettysburg. He also knew that the greatest part of the Union army was in the North so he wanted to destroy it and then head towards the capital for Lincoln's surrender.
Why, The Wilmot Proviso amendment would have closed California and New
Mexico to slavery in 1846 as a requirement for their annexation,
but Congress did not pass the proviso.
We can only theorize about how the life would be if the humans appeared earlier on the Earth, as we can not create a perfect and accurate picture of how would the things have been.
If the humans were developing in the same manner as we had, than we can say that the humans would have been much more advanced. The technology would have much better, probably missions to the other planets would have been regular. The population would probably be higher, with most of the population being concentrated in highly advanced megalopolises.
The environment though would probably be in a terrible condition, with enormous loss in biodiversity across the globe, decline in the forests, and much emptier (with life) oceans. On the other hand, there's every chance that with the more advanced technology multiple animals and plants would have been resurrected, even some extinct very long time ago.
