Changes in the ecosystem can occur at any time and can have many different outcomes. In paragraph 17, Darwin tells us about one of his explorations to find the meaning of the struggle for existence he came across something that could serve as great example.

Darwin uses another example from paragraph 20, talking about one of his experiments, that he had observed, finding that bees benefit plants in an area that they are located in. Without the bees species, in this case, the humble-bees, the heartsease, and red clover would sooner or later disappear. Field-mice holds …show more content…

Since the rise of Christianity, the concept of dominion has remained a constant staple in Western society. From the earliest passage in the biblical book of Genesis, God calls for man to “be fruitful and multiply, and fill the earth and subdue it: and have dominion over the fish of the sea and over the birds of the air and over every living thing that moves upon the earth” (1:28). This passage is the most referenced passage in arguing positions of contemporary domination of nature. The literal interpretation and implication of such a historical work has partly contributed to our current ecologic state. Alongside this, early scientific philosophies have greatly influenced the path in which we traverse today.

The reintroduction of grey wolves in 1995 into Yellowstone National Park had an incredible ripple effect that had an impact on multiple species of animals and plants. This reintroduction is a fantastic example of interrelatedness between multiple factors. Prior to the wolves returning to Yellowstone, the large population of elk was having a negative impact on other species around them. Without their main predator, the elk population in Yellowstone was able to not only increase but they were also able to remain in one area during the winter. The elk had no main predator to run from, therefore they would stay in one general area and use up the food sources around them, in this case being willow and aspen plants.

Introduction: This research proposal will focus on the important ecological topic of colony collapse disorder in bees. Colony collapse disorder is identified by rapid loss of worker bees that died away from the hive, leaving the young bees, or brood, and the queen bee. The disorder is said to be caused by several different factors, including, but not limited to, pesticides, diseases, pathogens, mites, commercial transportation and climate change. Without the worker bees, the rest of the hive would not be able to sustain itself and most of the bees would eventually die. This is an important issue in ecology because bees are crucial to many ecosystems as pollinators.

Bees are major factor in our environment. But recent studies show that we are to blame for the decline in the Bee populations.
