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.
Answer:
Many black men joined the Seminole Indians as warriors when their land or freedom was threatened.

Opium Wars, two armed conflicts in China in the mid-19th century between the forces of Western countries and of the Qing dynasty, which ruled China from 1644 to 1911/12. The first Opium War (1839–42) was fought between China and Britain, and the second Opium War (1856–60), also known as the Arrow War or the Anglo-French War in China, was fought by Britain and France against China. In each case the foreign powers were victorious and gained commercial privileges and legal and territorial concessions in China. The conflicts marked the start of the era of unequal treaties and other inroads on Qing sovereignty that helped weaken and ultimately topple the dynasty in favour of republican China in the early 20th century.
