Thirteen years ago, wolves were reintroduced to Yellowstone National Park. Of two potential locations considered (Snowflake Springs and Butte Rock) they were placed in the low-risk prey Butte Rock for the purpose of encouraging the wolves to spread out and create packs. Before and during the reintroduction project, Oregon State University researchers measured the rate of willow growth along 2.6 miles of the Gallatin River, which ran through Butte Rock and Snowflake Springs. During their study from 1998 to 2002, the researchers discovered that Snowflake Springs, where the elk were and no wolves lived, the willow growth dropped from 92% to nothing (“How Wolves Help Willows,” 4).
What was going on? Where there were no wolves and the elk had free reign of the land, they ate away the plants before said plants had a chance to mature and release more seeds to keep the cycle going. When extinction occurs, we’re not just losing the endangered species. We’re also potentially losing every species from animal to plant that is connected to it. This is what makes extinction the most pressing environmental issue that we face today.
Extinction itself has been going on since there were living things to go extinct; it has been part of Earth’s history from the very beginning, starting from the Cambrian extinction that extinguished 92% of all life on Earth, through the more recent Mesozoic extinction that wiped out the dinosaurs, and finally the pre-Cenozoic extinction that occurred at the end of the last Ice Age. Our planet has lost millions of unique species that will never be seen (outside of the imagination of artists and film special effects specialists) again. Extinction is a normal part of the natural world, and the Earth regularly purges pr...

...tes, a unique vegetable variety every six hours, and an entire language every two weeks. Pieces of our own culture, of the very essence of humanity, are disappearing along with the animals and plants that used to dominate this world. (Glavin 3)
Extinction is no longer just a natural process. It is an enemy, slowly changing our world into a barren wasteland where life is as rare as a flower in the Arctic Circle's winter. The wolf, the tiger, the caribou, the elephant, the bison, the cheetah, the sequoia cactus, the redwood tree – all of these and so many more things are on the verge of disappearing from our planet forever. Extinction is the most pressing environmental issue of our time, because if it continues the way it is going without anything being done to counteract its causes and consequences, there will soon be no environment left for there to be debates about.

Is Global Change Man Made? Essay

- Is Global Change Man Made. “The Earth 's climate has changed throughout history. Just in the last 650,000 years there have been seven cycles of glacial advance and retreat, with the abrupt end of the last ice age about 7,000 years ago marking the beginning of the modern climate era — and of human civilization. Most of these climate changes are attributed to very small variations in Earth’s orbit that change the amount of solar energy our planet receives,” says Nasa. This is leading into to the big debate....   [tags: Carbon dioxide, Climate change, Global warming]

The Current Extinction Rate Throughout the World: We Must Act Now Essay

- Human beings are heavily reliant on nature’s biodiversity. This biodiversity, however, is threatened by accelerating extinction rates which are approaching past mass extinction levels. Human activities are largely responsible for this trend, and, while there has been some success in preserving select species, the scale of the impending extinction will necessitate the conservation of existing ecosystems if biodiversity is to be preserved. Fortunately, the relative geographical concentration of most biodiversity makes such efforts both possible and economically feasible....   [tags: Environment]

Climate Change And The Global Warming Essay

- Climate change may be defined as a change in global or regional climate patterns. Jones (1986) first identified climate change in 1986. He confirmed that the climate has been changing since the early days of industrialisation. The issue of climate change is important due to the devastating effect it may have on people’s lives. Adaptation to climate change is highly crucial to survive therefore, its unpredictability is fatal. However, there are claims that climate change is a myth, which mostly is from multi-national companies that are highly dependent on fossil fuels, meaning that they are to blame for climate change....   [tags: Greenhouse gas, Carbon dioxide, Global warming]

Global Warming is Causing Climate Change Essay

- Global warming is the increase in the earth’s atmospheric temperature. Naturally occurring gases such as carbon dioxide, methane, nitrous oxide, ozone and water vapor trap heat from the sun, preventing it from leaving the atmosphere. These naturally occurring gases along with human made hydro fluorocarbons (HFCs), per fluorocarbons (PFCs), and sulfur hexafluoride (SF6) are collectively known as greenhouse gases. This essay will explain why global warming is fast becoming a cause for concern and why preventative measures are being taken....   [tags: Global Warming Essays]

Animal Extinction Of Endangered Animals Essay

- Wildlife has been living alongside man for as long as our species has been a part of this world, and the wildlife has even been here longer.

Many people, whether they’re aware or not, are slaughtering animals all the way to extinction, and there are definitely more ways than one that humans are partaking in the extinction of endangered animals.

Mass Extinction Essay

- ABSTRACT Several mass extinctions have occurred during the Earth’s history. The Cretaceous – Tertiary Boundary (K-T) Extinction caused the loss of at least three-quarters of all species known at that time including the dinosaurs. The cause of this mass extinction is a controversial subject among scientists but the fossil evidence of it’s occurrence is abundant. INTRODUCTION The K-T Extinction occurred 65 million years ago. Many species perished in that extinction. Today evidence for this extinction can be seen in the fossil record....   [tags: K-T Extinction]
