West Africa was one of the world's greatest producers of gold in the Middle Ages. Trade in the metal went back to antiquity but when the camel caravans of the Sahara linked North Africa to the savannah interior, the trade really took off. A succession of great African empires rose off the back of the gold trade as salt, ivory, and slaves were just some of the commodities exchanged for the precious metal that eventually found its way into most of southern Europe's gold coinage. Gold attracted unwanted attention and competition, too, with the Portuguese the first to exploit West Africa's coastal resources from the 15th century CE, and in their wake followed others. The discovery of the Americas and the gold of the Aztecs and Incas only gave West Africa a temporary respite as European colonial powers then returned to the continent as their chief source of slaves to work on the plantations of the New World. The trade of gold in West Africa goes back to antiquity with one of the earliest examples being the voyage of the Carthaginian explorer Hanno in the 5th century BCE. The celebrated mariner sailed out of the Mediterranean and, turning south, stopped off at the mouth of the Senegal River before sailing on and perhaps even reaching as far the Bay of Guinea. Hanno was followed by other countrymen, and commercial relations were established with the locals. Thus, West African gold found its way from the trading post/island of Cerne (unidentified but on the Atlantic coast) northwards to the ancient Mediterranean cultures for the first time.
The 5th-century BCE Greek historian Herodotus describes in his Histories that gold was traded on the West African coast using a silent and cautious method of barter - perhaps understandable given the language barrier and mutual fear between unfamiliar peoples. Hope this helps! Mark brainly please!
Answer:
A. have negative effects on the environment
Explanation:
Although mining is important for the country's economy, the environmental impacts of mining are diverse, ranging from specific local problems to large biological, geomorphological, water and atmospheric changes. Therefore, to know these caused problems and the minimization of their effects is of great necessity to guarantee the preservation of the natural environments.
Extraction of wood also has a negative impact on nature, with the greatest impact being deforestation. The first consequence of deforestation is the impairment of biodiversity, because of the decrease or even the extinction of plant and animal species. Tropical forests have enormous biodiversity and are therefore priceless. Many species, which are still unknown to the urban-industrial society, may be the cure for diseases and can be used in food or as raw materials. With deforestation, there is a risk that these species will be destroyed before being discovered and studied. In addition, the desmatamente destroys the home of many wild animals that end up going to the urban centers and could cause some inconvenience to the population.
<span>The person who most strongly influenced humane reforms for the mentally ill in the United States was Dorothea Dix, who lived from 1802 until 1887. Dorothea Dix was a school teacher from Maine who struggled at times with her own physical and mental health. This may have contributed to her becoming compassionate towards others who struggled with mental illness. In her lifetime, she founded over 30 hospitals dedicated to the treatment of mentally ill patients. She challenged a prevailing mindset of her day that people with mental illness could not be helped or improved. She was an advocate for the humane treatment of those in mental hospitals. At the time, common practices towards mentally ill patients included neglect, malnutrition, caging them like animals, and physically restraining them in such a way as to cause pain. Overall, Dorothea Dix spent 40 years lobbying the United States Congress to establish state hospitals for the mentally ill. She worked tirelessly to change how society views the mentally ill and to advocate for laws providing proper treatment for these individuals.</span>
