They worried that Lincoln would try to end slavery in the United States.
==========================================================
Explanation:
The issue of slavery was debated and fought over for many years before the election of 1860. It was only until Lincoln became president that sparked the southern states to secede, which led to the Civil War. Proof of this is found in the many Declaration of Secession documents produced by each state that left the union. This is basically a document explaining why they left the United States to form the Confederate States of America (CSA) aka the Confederacy.
In modern times, some people mistakenly claim that the Civil War wasn't over slavery but rather states' rights. This is simply false. The documents I mentioned prove that slavery was the core issue. More proof is the various states having issues with the fugitive slave act, in that the northern states didn't really adhere to the law to the level of the southern states' liking. I guess you could argue that states' rights were involved, but specifically the south fought to have the right to own slaves. In short, it's all about getting the correct context. Expanding that context, simply look at the decades preceding the war and notice all of the tension involving whether a new state was a free state vs a slave state.
The correct answer is - Large numbers of migratory birds;
The number of the migratory birds has always been pretty high and it hadn't resulted in the drying up of the Ogallala Aquifer, not to mention that those birds can not even reach that water because it is underground. Also, the number of the migratory birds have been steadily lowering, so even if they were using that water for drinking, it wouldn't have caused the drying out.
The Ogallala Aquifer has started to dry out because of numerous reasons, with the usage of its water for irrigation being the prime reason. The droughts have become longer, and the temperatures little higher, while the rainfall slightly smaller, so all of that affected the reserves of water in the aquifer negatively.
The industrial revolution made the world a positive some world meaning that was more resources to go around. But most of the resources were produced by the top 1% meaning that the richer got richer and the poor get poor.
