As human populations have changed over the years, people have altered the course of rivers and other waterways to better suit their needs. One approach has been through the damming of certain rivers. Over time, many people question whether this effort has been beneficial. What are the negative impacts of damming a river that are being assessed? Dams allow more water to flow into nearby reservoirs, increasing the chances of disease transmission.
Dams cause increases in salmon populations because more water is available for them to live in.
Dams reduce salmon stocks, which reduces revenue and overall whale populations.
Dams allow for invasive species to move around more easily, which reduces biodiversity.

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.
