Answer: B. logging and clear-cutting.

Air pollution is a problem in most major cities, and this pollution has several causes. Factory and vehicle emissions are two of the most important ones, while industrial pollution also contributes significantly. Logging and clear-cutting are the least important factors out of the options, as they do not directly contribute to pollution. However, abundant trees reduce the impact of pollution on the ecosystem, so logging and clear-cutting are still to be controlled or discouraged.

Explain the contributing factors to the patterns of the global silver trade between 1550 and 1800
Inga [223]

The increase in the trade of silver during the period between 1550 and 1800 is due to the fact that silver was started to be used as a standard currency for trade purposes. Even though it was not considered as "legal tender", as it would later be used for this purpose with the introduction "Bimetallism" in the 19th century, it was widely adopted as a tool for trade among the civilizations that existed at the time.
