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.
Definitely not A or D. Both B and C could be applicable

Answer:
We can think about the outcomes of this voyage in both the short and the long term.In the short term, the voyages led to the destruction of the natives of the lands that Columbus found. Some of them were killed outright. Others were enslaved. Many died of diseases brought by the Europeans. This was the main impact of these voyages in the very short term.Later, Columbus’s voyages led to the domination of the area from Mexico south to Peru by the Spanish. This resulted in the destruction of the major native civilizations like the Incas and the Aztecs. It also resulted in the enrichment and empowerment of Spain.
