Non-renewable resources are resources for which there is a limited supply. The supply comes from the Earth itself and, as it typically takes millions of years to develop, is finite. Non-renewable resources can generally be separated into two main categories; fossil fuels and nuclear fuels.
But there were pockets of the North on the eve of the Revolution where slaves played key roles in the economic and social order: New York City and northern New Jersey, rural Pennsylvania, and the shipping towns of Connecticut and Rhode Island.
A ship going to Africa to buy slaves carried a large cargo of mixed goods, such as cotton, brass pans and guns. These were exchanged for enslaved Africans, who were shipped across the Atlantic Ocean to north and south America and the Caribbean. Here they were set to work on the plantations (large areas of land owned by Europeans where crops were grown). The shipsâ captains would buy goods to take back to Europe. These would be goods produced by slave labour on the plantations. They were tobacco, sugar, indigo (a plant used for dye), rice, rum and cotton. The trade goods used for buying enslaved Africans were often produced and sold locally around Bristol.
