Whales are the largest marine mammal in the world‚ living in all of the major oceans from the Arctic and Antarctic oceans to the tropical waters around the world. Human whaling is to hunt and kill whales for the use of their meat‚ oil and blubber. It is estimated that three million whales were killed in the twentieth century alone. According to the survey‚ there are only 10‚000 - 20‚000 whales surviving in the oceans today. Rapidly decreasing number of whales has affected the ocean’s ecosystem.

Ocean OverfishingNicole HarrisENV/320June 23‚ 2014Frederick GrossOcean Overfishing Overfishing is a problem that occurs when fish are caught faster than they can reproduce. This is a problem that has been occurring for centuries and continues to be a problem today. Commercial fishing has driven many fish species to the brink of extinction. A scientific report done in 2003 estimates that industrial fishing “has reduced the number of large ocean fish to just 10-percent of their pre-industrial

wonderful is it to stand on pearly sands watching the pure blue sky‚ so lonely without a cloud or a plane or even a bird fluttering across it and as you admire it‚ the sun’s ray’s beams down at you. But at the same time you hear the wave’s chants on the ocean. A visit to the beach is one of life’s greatest pleasures. I always‚ always look forward to summer‚ it is my favorite season and it’s the perfect time to have serious fun. What I love most about summer is its weather. It‘s always hot‚ which allows

Conclusion The chemical changes in ocean acidification is known to be caused by an increase in the concentration of carbon dioxide (CO2) in the atmosphere‚ resulting in the lowering of the pH making water more acidic‚ an increase in dissolved carbon dioxide (CO2)‚ a reduction in the concentration of carbonate ions and an increase in bicarbonate ions. The oceans are currently taking up about one ton of carbon dioxide (CO2) associated with human activities per year. Almost half of the carbon dioxide

dumping trash in our ocean. Is not only going to affect us but also can kill animals and rare species that live in the sea. Without a clean ocean‚ our life’s can be in danger since we need water. The ocean is the most important thing in this planet so let’s keep it clean and alive. The Ocean is the most beautiful thing on this planet which hold many animals and creatures. But in this world‚ the ocean is disrespected in so many ways which are also killing animals in the ocean. In this Ad‚ it shows

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

Effects of Ocean Warming Around the World Global warming has become a very hot topic in recent years with the increasing global climate and amount of greenhouse gasses. A little known fact‚ however‚ is that about 84% of the total heating of the Earth over the last 40 years has gone into warming the oceans. This warming of the ocean is having widespread effects from loss of biodiversity to the increasing number of tropical cyclones. Even changes of less than 5°C are having effects seen around the

Ocean Acidification The main theme of the 3 articles is that the ocean is becoming more acidic due to fossil-fuel emission of CO2. The ocean has absorbed about 525 billion tons of carbon dioxide from the atmosphere‚ this reduces the amount of greenhouse gas in the atmosphere (1). ). It is lowering the pH by .1 units changing it from 8.2 to 8.1… it is becoming more acidic. (2). It happens when the CO2 from the air mixes with the sea water‚ it produces a bicarbonate ion. This bicarbonate ion then

Introduction The ocean has the oldest‚ most diverse‚ most numerous and least studied organisms on earth. It covers almost three fourths of our planet and has the potential to feed the world and supply cures for many diseases. Studying sea plants and animals is a challenge that is becoming easier due to advanced technologies such as deep-sea submersibles‚ sonar‚ lasers‚ videos‚ and satellites. In many cases‚ it ’s simply too hard to make a drug from scratch. The chemistry is too complicated. So
