An artificial reef is a human-made structure that is designed to mimic a natural coral reef. Artificial reefs may be created by sinking structures such as ships and oil rigs. Algae and corals attach to the sunken surfaces, forming the artificial reef. These reefs provide habitats for marine life and can also be beneficial in preventing beach erosion. Artificial reefs provide economic benefits by attracting divers and tourists. Some scientists worry that artificial reefs can damage the natural ecosystem if the sites and materials are not chosen carefully and monitored closely.

americans began to notice growing differences between the northern and southern sections of the country. there were more people living in cities in the north, which made it more urban. more people lived on farms in the south, which made it more rural. while many people were farmers in the northern states, there were now other ways to make a living, such as working in mechanical cotton gins factories manufacturing cloth, tools and other goods. people in the north supported high tariffs on goods imported from europe because the extra cost encouraged people to “buy american” instead. in the southern states, planters did not like tariffs because they sold most of their production to europe and bought their tools from there as well. southerners believed the protective tariff was something that only northern factory owners keep their profits high. so the southern politicians came up with an idea. they would opt out. they would simply ignore the protective tariff. it was ‘null and void’ in south carolina. the state would not collect the taxes on goods imported into south carolina, no matter what the president said they had to do. this decision led to the nullification crisis.
