The problems the oceans are facing

The present article is exploring 7 issues that our oceans are facing. It is important to raise awareness about the destructive impacts humans have on them. It also states that we use all the good resources it gives us and we use it as a dump afterwards by dropping all our waste in it. The first problem humans cause is overfishing. We do not think about all the other species that are killed while fishing in the ocean with our big nets, causing troubles in the aquatic life. Furthermore, by taking huge amount of fishes, we are breaking the marine food chain and by consequent, starving other marine animals. The second problem is the killing of sharks. Indeed, many people catch sharks cut their fins and let them die in the ocean after releasing them. The fins are used for some kind of soups but it has important impacts on the population of sharks. Since they are high in the food chain, they do not reproduce easily, hence the population is decreasing. This practice is making the balance of our oceans in danger. The 3rd problem is ocean acidity. In fact, oceans absorbs Co2 but since we are producing way too much of it, the ocean absorbs it in too high quantity making the PH level dropping and causing troubles for the marine life to survive. The forth issue is the high number of dying corals reef. Because of global warming, many of them are bleaching making the habitat of many small species in danger. It is important to keep them healthy in order to assure a good food chain. The fifth concern is the growing rate of dead zones in the ocean. Indeed, dead zones are places in the ocean where there is no aquatic life because of the level of oxygen that is too low. This is in part caused by global warming and its growing fast pace is concerning many people because it is very bad for the health of the oceans. The sixth problem is the high level of mercury in the ocean. Ironically, we are causing this problem by polluting and it is coming back to us by the intermediate of eating aquatic animals. Actually, mercury infect the ocean due to the pollution and fishes get also infected and they finally end in our body when we eat them. This situation is supposed to rise because of the growth of even more coal plants. The last issue is the formation of the giant plastic patch on the ocean made out of pollution. Actually, it is visible from space and it concerns many ecologists. This ‘’island’’ proves that we must lower our pollution and be more careful with the maintain of water bodies. 

 

In my opinion, it is possible to slowdown all these issues and maintain the viability of our oceans. In fact, by lowering out emission of CO2, we would decrease our pollution and the level of acidity would be better in the oceans. This is probably a small step in the direction of the ‘’health’’ of our ocean but it would definitely make a difference. I also think it is important to raise awareness of what is happening to our water and aquatic life in order to make a difference.

Comments

I have chosen to comment on this summary; the problems the oceans are facing. When reading this, the first piece of information that shocked me was just how much fishing can affect other parts of the ocean. Fishing can actually affect the whole marine food chain. I find it heartbreaking that humans are hurting and killing such precious creatures. I was also affected when I read how we are creating huge issues in the oceans like ocean acidity, dead zones, and high levels of mercury. No one should have enough power to construct such problems.
After reading this very informative summary, I have come up with a theory. I believe that it is possible to start preventing these issues, and hopefully one day the oceans will start becoming healthy again. Humans have to work together, that is the only solution. We must stop polluting to prevent more ocean acidity, and we must put an end to global warming to stop ocean dead zones from being created. Although it is easier said than done, there are little steps to take to reach this goal (cutting down on meat, using electric cars, using public transportation, bicycling or walking, etc.). And the most obvious solution; stop fishing! The fish are not ours to take, especially if it means negatively affecting the whole marine food chain. In all, I truly hope humans will being working together to save our oceans and our sacred planet.

In the article "The problems the oceans are facing” by beatricegiguere, the author reviews and summarize an article about the destruction of the ocean ecosystem that are done mostly by human. Most of the damage listed in the article that Giguere wrote come from plastic pollution, overfishing and CO2 emissions. Furthermore, overfishing according to Giguere is causing many marine species to starve due to the fact that it breaks the food chain. In addition, she includes carbon dioxide emissions which slows down the oxidation of oceans thus stopping oxygen to get through the waters in so creating dead zones. Finally, there the mention of plastic that create more ocean acidity by increasing the level of mercury. Moreover, Giguere proposes a theory to reduce this impact by cutting down on meat, using electric cars, using public transportation, bicycling or walking, etc. The other the solution is to stop fishing. Although I find it interesting that carbon emission can cause damages and a way to reduce it is to use green incentives products to cut carbon emissions I agree. However, to stop fishing is a disagreement because, it is a market that feeds 1 billion people in the world in which some of these people don’t have easy access to other meat and perhaps vegetables and fruits. In so, to stop fishing would be harmful to 1 billion human.

Response 4(oceans and fisheries/agriculture)
I choose this particular summary to comment on because, I was drawn to the fact that you mention that there were 7 major issues that our oceans are facing, and was curious to find out what those 7 were as well as the effects they may have on climate change and possibly our food supply. Based on some of the information I found from another source, I agree with a few of your points. For example you mention how today’s oceans are heavily polluted with waste, according to my source it says “that despite recycling being the solution for disposables 90% of plastic globally isn’t recycled (Greenpeace,N.D,p.8)” most of which are ending up in our oceans, it continues to state how if we don’t change quickly, future generations are at risk of inheriting a dump rather than an ocean. You also covered the fact that we are overfishing is affecting the oceans food chain. The information I found agrees, it says how we have already removed the majority of large fish in the ocean, specifically a whooping 2/3rds and how “one in three fish populations have collapsed since 1950(Greenpeace,N.D,p.8)”. What I found interesting from doing research regarding your response is that I learned the economic effect and importance of the oceans being able to provide a food source for poorer countries. According to my article it says how “more than 3 billion people rely on our oceans and coastal ecosystems for their livelihood(Greenpeace,N.D,p.8)”. Due to the lack of fish in the ocean’s it has made it very difficult for many fisherman and companies to make a profit this creates a certain drive to overfish in hopes of being able to turn that profit which in turn threatens our oceans as a whole, all this to say I also agree with you on the fact that we need to raise more awareness on the matter if we are to make a difference before our oceans become barren.

I chose to respond to this summary because I find that it has a lot of interesting information concerning the problems oceans have to deal with nowadays. In an article that I found on ocean acidification, I learned that types of aquacultures such as oysters within Washington State were depleting, which gave that first signs of ocean acidification to the state (Craig, 2015, p.1629). Not only does it affect the life in the ocean, it also has repercussions for people because of its impact on the economy (decreases revenues from fisheries and oyster cultures) (Craig, 2015, p.1629). Most of the ocean acidification comes from sources such as emissions of carbon dioxide and nutrient pollution in the water, closely linked to human activities (Craig, 2015 p.1629). In the state of Washington, a council was made to discuss the issues and possible solutions of ocean acidification, which led to a report that illustrated what should be done (Craig, 2015, p. 1630). I think that more of those types of reports should have a significant impact and should be followed by our politicians if we wish to find a balance between our consumption of earth’s resources and what it is able to offer us.
