What have scientists concluded about the levels of plant and animal biodiversity on easter island in the past?

Scientists have determined that Easter Island used to be enormously diverse in biodiversity. Scientists examined the number of bones and pollens that were buried, to support their assumptions. The biodiversity in the past was extremely high in comparison to the biodiversity of Eastern Islands at present.

It now comprises only a few insects and very slight vegetation, however, it is used to be a sub-tropical rain forest. Though, the present levels of biodiversity cannot be illustrated in terms of complexity but instead in the disturbance.

Due to the past populations of the Easter Island, their disturbance on the once paradise is now barren of shrubs and sand, leaving less complexity.

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.
