Answer:
Humans cause change in the environment as there is overwhelming evidence that human activities, especially burning fossil fuels, are leading to increased levels of carbon dioxide and other greenhouse gases in the atmosphere, which in turn amplify the natural greenhouse effect, causing the temperature of the Earth's atmosphere, ocean, and land surface to increase. That greenhouse gases "trap" infrared heat is well established through laboratory experiments going back to 1856 when Eunice Foote first measured the effect.The well-documented trend of increasing of CO2 in the atmosphere is caused by the burning of fossil fuels and massive land cover changes. The "smoking gun" that shows clearly that human activities are responsible for recent increases in carbon dioxide in the atmosphere is provided by carbon isotopes (carbon atoms of different atomic weight). These isotopes allow scientists to "fingerprint" the source of the carbon dioxide molecules, which reveal that the increased CO2 in the atmosphere is caused by fossil fuel burning also.
One could make the argument for any one of the aforementioned events. However, I would have to argue that the Louisiana Purchase was the most significant for a few different reasons:
1) Jefferson used the concept of implied powers in order to buy this land from France. Nowhere in the US Constitution does it say that presidents can buy land from foreign countries. However, Jefferson argues that this power can be implied. Due to Jefferson's actions, several presidents after him will follow suit and buy territories from other countries.
2) It doubled the size of the United States.
3) It initiated the US's policy of Manifest Destiny. This concept that America should control all land from the Atlantic to Pacific Ocean was one that was introduced in the early 19th century. The first big land annexation of this time was the Louisiana territory (1803). After this purchase, the US would continue to grow in size thanks to buying land from other countries and war.
Answer:The goal of the United States was to stop the spread of communism while the Soviet Union wanted to spread communism in order to increase their own sphere of influence. Throughout the more than 4 decades of the Cold War there were numerous proxy wars, some of which continue to this day and all of which have lasting repercussions.

Here is some information to help you answer this question:
Reasons to vote for a 3rd party candidate
1) The person represents your views on society.
2) Show your displeasure with the two-party system. This is a powerful message to political officials. If thousands of individuals who feel left out of both the Democratic and Republican party vote for a third party candidate, it will shift the way politicians approach third-party candidates.
Reason why it would be considered a "waste"
If a third-party candidate has no chance of winning, some would consider it a waste. This is due to the fact that your vote could have been used to support a candidate with somewhat similar views who actually had a chance at winning.
