Haiti suffers a very high degree of deforestation. This is because charcoal is intensively used for cooking; people in need of money cuts down trees because of this.

European colonization had both positive and negative impacts on Native Americans.
Positive
One of the positive elements of European colonization was the introduction of new crops from Europe to Native American tribes. Thanks to the Columbian Exchange, Native Americans had the ability to gain resources such as pig, sheep, cows, and bananas.
Negative
One of the negative elements of European colonization was the decimation of the Native American population. When Europeans came to North America, they brought over diseases that Native American tribes had never encountered. This negatively effected them, as they had no immunity to these diseases. This resulted in the deaths of millions of Native Americans throughout the 16th and 17th centuries.
Three factors fueled American Imperialism.
