Pluto Change Society

Decent Essays

Have you ever thought about how Pluto was a planet and the next day it wasn’t? Well, this isn’t uncommon; scientific knowledge changes again and again. Things that we think are facts could actually just be scientific theories and could have easily been changed. We should acknowledge the change and see things that have changed like the food scale and the organization of organisms. Scientist fine new evidence every day and it has a big impact on our society.

To start off, we should acknowledge the change in scientific evidence. You could be a quick google search away from seeing what has changed and how it impacted our society. For example, it shows in recent studies that dinosaurs have feathers. According to “The Half-Life of facts”, “Scientist …show more content…

The scale has changed from a pyramid to a plate. The old pyramid was deeply flawed for many reasons, one being it was hard to distinguish between healthy and unhealthy foods. For example, consumers couldn’t didn’t know how to identify between healthy choices whole grains and fish to unhealthy goodies like whole bread and bacon. According to Neuman, the pyramid was currently appearing on boxes of foods and was so streamlined of information no one had an idea of what it meant. Many nutritionists will mourn the loss of the food pyramid because the new scale will easily show consumers the basics of a healthy diet. The new scale will have a plate shaped symbol which will be sliced into 4 wedges, with a circle right next to the plate. Neuman says in his article “The Food Pyramid and Why It Changed”, “it consists of four colored sections, for fruits, vegetables, grains, and protein…Besides the plate a smaller circle for dairy.” It will be difficult to do better than the new food plate Walter Willett (chairman of nutrition department at the Harvard School of Public Health) says, but who knows what new information will come …show more content…

Scientist believe that there are still 85% of organisms undiscovered. Many of these species live in places that are unexplored. Recently scientist have explored the floors of the oceans, eyelids of humans, hot springs, and even stomachs of humans. Before the 18th century, organisms were classified into three groups. These groups were those that live on land, those that live in water, and those that live in the air. Also plants and animals were called by their common names, which lead to much confusion. According to “The Explosion in What We Know About Life Forms”, many confusions arose from organizing organisms this way, such as, scientist could not be sure whether two similar organisms that lived in different parts of the world were actually the same creature called by two separate names. Later in the 18th century, a botanist name Carl Linnaeus created a new, complex system of taxonomy. In this system, it grouped organisms (from largest to smallest) into kingdoms, phyla, classes, orders, families, genera, and species. Also in the new complex system they took the genus and the species of each type of organism to create its name. As scientists learn more about the animals and plants on earth they have improved the taxonomy system. In the essay “The Explosion in What We Know About Life Forms” it talks about how scientist have added three new kingdoms, subspecies/varieties (smaller than
