How The Environment Is Focused The First Video Essay

3. (a) A dark brown mice on dark colored soil is more likely able to escape under a full moon, which makes it easier for the mouse to blend in. (b) A light brown mice is more likely to escape on light colored soil during a night with no moonlight. This is because the

According to Darwin and his theory on evolution, organisms are presented with nature’s challenge of environmental change. Those that possess the characteristics of adapting to such challenges are successful in leaving their genes behind and ensuring that their lineage will continue. It is natural selection, where nature can perform tiny to mass sporadic experiments on its organisms, and the results can be interesting from extinction to significant changes within a species.

Chimpanzees have what is called melanin, which is a dark brown pigment that protects them from UV radiation. Melanin is a natural sunscreen, which filters out UV radiation. It is been proven that people with high concentration of melanin in their skin heading to come from tropical areas and it has protected them from skin cancer. After all of this research, Jablonski and Chaplin then ask, “what role melanin might play in human evolution?” (170).

Environmental scanning can be viewed as a way of acquiring information about outside events that can aid organizations in first identifying potential trends, then interpreting them

Majority of mice in New Mexico’s Valley of Fire have dark color. The population increase of dark-colored mice in Valley of Fire happened because of natural selection. Mice that do not suit the environment, which are light-colored mice, cannot survive in Valley of Fire because they are easily noticed on dark soil by the predators. On the other hand, dark-colored mice can hide easily on dark soil, which made them survive. Whereas the mice near the desert are mutated, those near the lava are not mutated. Each mouse from different lava found to have a different gene. Whereas the mice near the desert’s color change was from a random mutation, that of the mice near the lavas was not random. Because, each dark-colored mouse from two different lavas

The supply and demand are the main driving forces within this market, it can cause a change instantaneously overnight, and these cost issues are immediate to the consumer. There could be a fire in one of the local refineries causing product shut down, this can create a panic at the pump as well. There are many reasons why this product is so volatile, it cost too much money to refine and thereby is restricted in the method of refining. Supply means that there is a large supply available for product usage, pricing goes down, too much product, if the Demand is exact opposite occurs and there is short supply and the pricing is extremely quick to be changed at the pump. The markets can be also affected; they can be changed no matter how far the original production occurs, economics are disturbed, countries global markets respond to higher cost factors to operate business development causing inflation to jump to higher records slowing down global progress.

I grew up in a fairly average Los Angeles suburb, so I don’t have the tight knit connection with nature that some from more rural locations might have. My interaction with nature in my early years was quite limited. I went on a few hikes with my family and occasionally went to the beach. But the one aspect of nature I’ve always been fascinated with is space. While this may not be what most of us think of the “environment”, it has deeply impacted the way I see the world.

The Rock Pocket Mouses’ coat color is extremely important because the mice use it as a mean of camouflage if the mice are a different color of fur than its environment, their overall fitness, how well an organism can survive and reproduce in its environment, decreases. Due to a volcanic eruption, most of the environment has turned from a sandy-colored soil to black soil; therefore making it very difficult for the unmutated, pale mice to survive. The dark fur color of the Rock Pocket’s population occurred due to a random mutation, a mistake made in the DNA whether it is good or bad, known as the MC1R gene. Because of this, variation among the mice was created, making some mice dark-colored and others to stay light-colored. Dark-colored mice

Environmental Impact of Personal Lifestyle: Behavior # 1 A major lifestyle behavior of mine that effects the environment is the over usage of water. Water waste is a problem for many people in their households. We can start conserving in our homes which most of our water is wasted daily and we do not pay attention to it. Water is used for daily activities such as taking a shower, brushing teeth, washing the dishes, etc. My personal problem is over usage in the shower, I like to take at least a 30 minute shower. Another major problem is when I let the water run when I am brushing my teeth.

In this chapter, the topics of natural selection and the struggle for existence. He makes the important point that these two concepts are intertwined, especially because the struggle for existence will eventually ‘weed out’ some organisms while those who have variations which are favorable for the environment will survive, adapt and pass on their genes to the next generation. He also highlights the role that the environment plays in the struggle for existence; a particular variation might let a species thrive in one environment but might be disadvantageous in another environment. In this way, the most useful adaptations for success in a particular environment is inherited by offspring and the less advantageous characteristic die out as organisms that possess them do. He also talks about the role of nature in the struggle for existence by citing the fact that events like natural disasters and even predator-prey relationships allow for the survival of some organisms,

"Climate is the product of two factors: the long-term patterns in the circulation of the atmosphere and oceans, and topography, the very slowly changing shape of the land surface" (Lee et. al, 2013, p. 101). The topography of the earth has changed due to human actions which has resulted in an increase in erosion. "The process of natural selection: a population is selected by natural forces such as the ability to elude predators, survive drought, or reproduce" (Lee et. al, 2013, p.113). The use of the phrase "elude" suggest that animals settle in place where they are not hunted or displaced. We as a civilization have begin to take over their land or area. The outpouring of of biological diversity calls us to marvel at its fecundity. It also

Environmental worldviews are how people think the world works, where they fit, and how they think ethically and morally. These views can be human centred, earth-centered or a combination of the two(Tucker and Grim, 1994).
