1. Marine Science – The affirmative argues that current investments in ocean research are inadequate and will continue to decline into the future. Because of funding issues, the world lacks proper information about the effects of global warming on marine ecosystems globally which prevents effective solutions. That ensures inevitable biodiversity loss which results in the human population exceeding the Earth’s carrying capacity, causing extinction.…
For Activity A, we first tested enzyme activity. First, we used an H2O2 syringe to transfer 10 mL of H2O2 into an unlabeled 60-mL cup. Then, we used a transfer pipet to add one mL of catalase solution into the unlabeled 60-mL cup that we put H2O2 in. After that, we observed the solution for one minute. Then we tested the effect of boiling on enzyme activity. First we used a transfer pipet to transfer 4 mL of catalase into a test tube. After that, we placed the test tube filled with catalase in a boiling water bath for five minutes. While we were waiting, we rinsed the unlabeled cup we used earlier when we tested enzyme activity. Then we used a H2O2 syringe to transfer 10 mL of H2O2 into the rinsed unlabeled cup. After five minutes, we transferred 1 mL of the boiling catalase into the unlabeled cup with H2O2 in it with an unused transfer pipet and observed the results. After testing the effect of boiling on enzyme activity, we tested for catalase in living tissue. First, we rinsed the unlabeled 60 mL cup we used earlier. Then, we used a scalpel to cut a small piece of liver. After that, we macerated the piece of liver with a glass rod. When the liver was macerated enough, we put it in a cup with 10 mL of H2O2, which was transferred into the cup with a H2O2 syringe. Lastly, we observed the cup.…
In The Truth about Ocean “Acidification”, by Patrick Moore, the term “ocean acidification” has been fabricated, and people do not see the positive effects it has on marine life. In 2003, many articles on ocean acidification were published. Moore challenges one of the article’s hypothesis that corals will cease to grow by mid-century, and ocean acidification will impact fisheries worldwide. Moore emphasizes that there are five key reasons why the ocean acidification narrative is a fabrication. First, the concentration of Co2 was much higher in the earth’s atmosphere during the Cambrian period. Next, most of the invertebrates with the ability to produce calcium carbonate armor are capable of rapid adaptation. Third, there are two distinct physiological…
Climate change’s equally evil twin seems to be ocean acidification. 25 percent of the CO2 dissolves into the ocean instead of being in the air. When the industrial era started over 525 billion tons of CO2 were absorbed (22 million tons per day). Scientists at first thought that we were good because it warms the planet, but that’s not the case. The ocean is becoming more acidic than ever because of the CO2. 200 years later the water temperature increased by 30 percent. Rivers usually keep the ocean stable because they have to carry all of the chemicals, but they haven’t been able to keep up with all of this CO2. As a matter of fact some of these animals’ shells dissolve in this acidic seawater which doesn’t help at all. With…
Some issues that are known to cause ongoing problems are air quality, climate change, habitat and wildlife, pollution and waste, water, and weather.…
This sea is predicted as how the oceans of the planet will look like within the next century. The acidification that might happen throughout the oceans of the world is mostly caused by the carbon dioxide emitted from smokestacks and tailpipes. (527) Thirty percent of the carbon dioxide released by man has been soaked in the oceans. Many marine organisms cannot survive in these high carbon dioxide concentrated conditions. The evidence from Castello Aragonese proves that this polluted sea is missing thirty-three percent of marine organisms that live outside the vent system. Another significant organism of the chemistry of the ocean is the coral reef. Coral reefs are essential for the ecosystem of the ocean. Ocean acidification is a threat to their existence. According to Jane Lubchenco, ocean acidification is global warming’s “equally evil twin.” (qtd. in…
This proposition can divide into a multitude of different topics. There are three very important claims that have to components to global warming? What are the challenges we confront when we are dealing with the issue? What are the effects resulting from unresolved issue and finally what solutions can be proposed to solve the problem.…
The issue I chose to write about is health and the significant impact that it has on millions across the world in our society. In relation to the environment, there are certain types of health risks that can play a major part such as: cancer, mortality, certain disabilities, and how all of these things are managed on a consistent basis. These environmental issues affect everyone, not just one particular person or type of group amongst us all. For this reason alone, it is imperative to bring light to each individual situation and develop some sort of change to create a basic balance throughout the world. There are many causes that make these issues prevalent such as toxins that pollute…
Ocean acidification is caused by CO2 in the atmosphere when it reacts with water it creates carbonic acid. It's a significant and harmful consequence of excess carbon dioxide in the atmosphere that we don't see or feel because its effects are happening underwater. When carbon dioxide is absorbed by seawater a chemical reaction occurs that reduces the seawaters pH, carbonate ion concentration, and saturation states of biologically significant calcium carbonate minerals. It decreases the pH of seawater, meaning it increases the seawater’s acidity. Over the past 250 years, ocean acidity has increased by 30 percent. At least one-quarter of the carbon dioxide CO2 released by burning coal, oil and gas doesn't stay in the air, but instead dissolves…
Unless you live under a rock, you will have noticed what’s happening around the human race due to global warming and climate modification. It is not only affecting us humans, it is also affecting our vegetation, our animals, and our oceans. I recently watched a video by National Geographic about the precious coral reefs in the Florida Keys and it talked about how the coral reefs cannot keep up with the rising sea level, so eventually they will all just die (“Fighting to Save Coral in the Florida Keys”). Additionally this will lead to habitat loss and then species dying off. If this scenario belonged to one area it would be tragic but climate change is disrupting habitats and killing off dependent mintage humanity worldwide.…

This research project investigates how the pH of ocean water affects the mass of the shells of sea organisms. People who might benefit from this project are Oceanographers and Fisheries. The resources used included an article from the website Smithsonian National Museum of Natural History, called “Ocean Acidification” by Jennifer Bennett, an interview with Dr. Andrew Dickson, a professor of marine chemistry at the Scripps Institution of Oceanography, University of California, San Diego, and an article from the website PBS News Hour, called “Coral Reefs and Shellfish Battle Acidifying Oceans”, by Saskia de Melker. From this research, one can conclude that rising acidity and decreasing pH have had and will continue to have a huge impact…
Global warming is currently the most controversial issue.The debate over global warming has been going all around the world and it seems endless. Depending on one's political view, whether a person is a liberal or a conservative may consider global warming as the biggest challenge facing humanity or one may dismiss, saying it is not real or may simply claims global warming is a hoax. However, there are strong, credible evidences that indicate the extreme and unpredictable weather pattern we have been witnessing like extreme heat, drought, storm , retreating glaciers and the melting of the arctic sea ice, and rising sea level due to climate change caused by human activities. Governments and people around the world should hold hand in hand…
Oceans, lakes and rivers absorb 30 to 40% of the carbon dioxide produced by the human population. Ocean acidification has been a rising issue for the last three decades, and oceanographers have been studying the carbon dioxide effects on the ocean throughout that time. It is becoming increasingly problematic because the levels of carbon dioxide being emitted into the environment are greater. In the last 200 years, the ocean has become 30% more acidic because as more carbon dioxide is dissolved into the water, the more acidic the water gets. This is destroying the marine life that has had a stable pH level of ocean water for thousands of years. The oysters have been highly affected by the ocean acidification.…
The earth's climate is dynamic and always changing through a natural cycle. What the world is more worried about is that the changes that are occurring today have been speeded up because of man's activities. These changes are being studied by scientists all over the world who are finding evidence from tree rings, pollen samples, ice cores, and sea sediments. The causes of climate change can be divided into two categories - those that are due to natural causes and those that are created by man.…
