Climate Change And Its Impact On The Environment Essay

Everyone talks about climate change and how the Earth is slowly deteriorating, but no one seems to have specific examples. In Linnea Saukko’s “How to Poison the Earth,” she does use specific examples of what is causing climate change. She uses satire with a hint of sarcasm in her essay. She gives the reader specific examples of how to poison the Earth, but not really wanting to poison the Earth. Gretel Ehrlich writes her essay, “Chronicles of Ice,” a little differently. She uses personal experiences of visiting a glacier and the way that it is falling apart to explain climate change. She uses detailed, sensory description to explain

We performed an experiment on crayfish focusing on their metabolic rates, via oxygen consumption, at two acclimated temperatures. Crayfish were either acclimated to a warm temperature (20 to 25C) or to a

In this experiment, an oxygen-measuring probe was attached to an oxygen chamber in order to quantify oxygen consumption rate, which served as a substitute measure for metabolic rate. The oxygen-measuring probe provided real-time measurements of dissolved oxygen (DO) concentration present in the chamber water. The oxygen chamber was sealed to create a closed system so that over time, the oxygen levels would decrease as the goldfish respired and consumed the oxygen present in the water. The software LoggerLite was used to record real-time DO concentration measurements.

For the first trial, the joint mass of the two goldfishes was 9.32g. Figures 1 and 2 were graphical representations of the oxygen concentration within the chamber over a period of ten minutes for the first trial. Since the decrease of the oxygen concentration is inversely proportional to the increase of oxygen consumption, the following data will report negative rates in oxygen concentration as positive oxygen consumption rates. Figure 1 depicted the data of the controlled run and reported a negative slope, indicating an oxygen consumption rate of 0.0007 mgO2L-1s-1. Figure 2 depicted the data from the experimental run, in which the goldfishes were subjected 100mL of the nicotine-treated fish water. This data from the run revealed a positive slope, which indicated an increase in oxygen concentration; therefore the oxygen consumption rate is a negative value of 0.0001

The purpose of this lab report is to determine the effects of a different environment condition such as temperature on the consumption of oxygen and ventilation in goldfishes (Carassius auratus). The consumption of oxygen and ventilation rate was measured in goldfishes at different treatment levels inside the tanks; ~ 25°C and ~15°C in a 15 minute time interval for one hour. At ~ 25°C, the ventilation rates in the goldfishes were higher than at ~ 15°C and there was more oxygen consumption at ~ 15°C than at ~ 25°C. The results suggest that the ventilation rate is greater in high temperature than low temperature. Also, there is more oxygen consumption at lower temperature than at higher temperatures. This experiment shows that temperature is

Both temperature and chemical changes to the environment were observed to effect the daphnia’s heart rate. Increasing water temperature

In general, the rate of physiological processes increase as the temperature and oxygen concentration increase (Buentello et al., 2000). The main controlling factor for fish or shrimp feeding, metabolism, and growth is temperature. The growth rate is reduced if the energy demand of increased metabolic rate exceeds the gain from increased food consumption (Brett, 1979). When the food supply is not limiting, the specific growth rate of most aquatic species increases with rising temperature (Talbot,

Climate change is a rising issue of importance in our day and age, and one that is threatening our global society on many levels. In the past few decades, scientists have discovered that our planet’s climate has been changing at an alarming rate. The way in which we have changed the land to

In our study, we had two separate experiments to test whether the water temperature impacts the locomotive activity of Hemigrapsus oregonensis. We modified our second trial by using water of higher temperature variations (more severe environment), removing the sand from the bottom of the tub, and introducing 5 seconds acclimation period before we started the three-minute-timer. With modifications, we recorded two absolutely opposite results from two trials: in the first trial, the data illustrated that the crabs moved a longer distance as temperature increased, but in trial two, crabs appeared to be less active and moved less as we raised the temperature. A study by Gillooly (2001) proposed that higher temperature, which is the result of higher kinetic energy of cellular components, is linked to resting metabolic rate being higher. Species with higher metabolism synthesize more ATP in their bodies, and consume more oxygen to move around. Furthermore, scientist Burggren (1997) claimed that almost all poikilothermic animals follow a similar pattern: a decrease in body temperature will result in decreasing cardiac activities. Since body temperature changes along surrounding temperature, a change in water temperature in our case will also indirectly affect the cardiac activity of H. oregonensis. The main function of cardiovascular system is oxygen and nutrient transportation. The central cardiovascular system may slow down because of a decline in temperature increase the

From a sample size of eight measurements taken from eight different gold fish population, a two-tailed, paired t-test was conducted to determine the relationship between the metabolic rate of gold fish before and after the increase of environmental temperature. As shown in table 1, for the control group, or the population before the increase of environmental temperature, the mean amount of oxygen consumed per hour per kilogram of fish was 267 delta[O2]/(hour*kg), with a

Climate is inherently variable. Climate changes from place to place and it varies with time. The world now faces one of the complex and important issue it has ever had to deal with: climate change. Climate change today is one of the biggest concerns of human beings on the planet and the effects of climate change are undeniable and it may cause environmental, social, and economic threats to the planet. We already know and easily can highlight several signs of climate change. They are: rising global sea level, widespread melting of snow and ice, rapidly changing ocean and global temperatures, and other signs. So, what are the causes of climate change? Is it natural or do human beings cause it? Well, in both cases we would be right. The climate change can be affected by natural factors, such as solar output, volcanic eruptions, and the Earth’s orbit around the Sun. Also, climate change can be affected by human activities such as, deforestation, burning fossil fuels, causing ozone hole, and building mass destructive weapons and using them on earth that causes a huge radioactivity on earth. Currently, the threat of global climate change does not threaten some nations to the extent of others. Compare the United States with the rest of African countries. We live in prosperity and in much easier time than the rest African countries. Most African countries cannot grow anything on their lands because of climate change. At the end, climate change might affect everyone on

“Our generation has inherited an incredibly beautiful world from our parents and they from their parents. It is in our hands whether our children and their children inherit the same world” (Richard Branson). This quote is a brief rewording of the issue we have today with global warming. For those who are not aware of what global warming is, it is when too much carbon dioxide is added into the atmosphere. Global warming can cause sever hurricanes, intense weather, and many other natural disasters. For example, the lack of protection to our species and natural resources has led to many conflicts around the world. The lack of conservation of natural resources and need for habitat protection has had a major impact on the environment also.

Global climate change is real, it has noticeable effects on the environment. Climate change in the earth is caused by numerous activities. When climate change happens; temperatures can rise tremendously. Rapid warming notice nowadays is uncommon in the history of our planet. The rising temperatures will have great effects on the plant’s climate patterns and on all living things. When temperatures increase, different adjustments can occur on earth. For example, it can cause droughts, floods, air pollution, as well as extreme heat waves. Oceans are also experiencing changes: oceans are warming and becoming more acidic, glaciers are melting, and sea levels are rising. As these adjustments will occur in the future, it will cause challenges to our society and environment.

Climate change could be described as any process that causes adjustment to climate system be it a volcanic eruption to a change in the solar activity. Today, however, the phrase is most often used as climate change caused by humans. Climate change is also used commonly with another phrase – "global warming" – reflecting scientific observations of strong warming trends over the past century or so. Indicators like rising sea levels, retreating snow cover and glaciers, longer growing seasons and shifting wildlife has alarmed scientific community unanimously agreeing that the earth has warmed in the last century. Experts however are of the opinion that climate change is a more accurate phrase than global warming as the latter is just one component affecting the larger climate systems of the earth.

Some people say global warming is caused by human activity, others say global warming doesn’t even exist.
