How humans Impact marine ecosystems
How Humans Impact Marine Ecosystems

Earth consists of many complex organisms that share and benefit from all of what the world has to offer. Conservation and protection of marine life is becoming more significant as humans better understand the importance of the oceans and how people have an affect on them. Just as people treasure and protect areas of land it is just important to treasure and keep the oceans safe. Marine life is becoming increasingly damaged because of threats from human activity throughout waterways. Through John C. Brigg’s article, and further research, I have discovered that the best way to conserve marine ecosystems is by better understanding people’s negative impact on the oceans, what exactly humans are impacting, and the oceans importance to life and survival.
In Marine Biology, John C. Briggs talks about the biggest threats to the oceans, which include, overfishing, habitat destruction, pollution, global warming, and costal expansion. These activities are wiping the ocean of marine life. Humans must make better choices so people can continue to support the oceans.
Briggs opens by describing how habitat destruction can be a substantial stress on marine life. Human activities have a major role in the destruction of habitats as people move closer to the coast. Boaters and builders tear through ecosystems that inhabit marshlands and grasses along the shoreline. He states in Marine Biology, “many species that are typical of costal and estuarine waters have been reduced by habitat destruction in bays and along coast lines” (Briggs 486). In making this comment, Briggs argues that ruining these habitations causes a reduction to those who reside there. The damage done to these territories makes it impossible for marine life to continue living in these same areas.
As Briggs explains habitat destruction, he talks about things such as pollution and waste being a great danger. A main pollutant in waterways is fertilizers and pesticides

    Marine habitats are in grave danger due to humans and Mother Nature. Hurricanes, typhoons, storm surges, and tsunamis are factors in which contributes to the destruction of marine habitats and are caused by Mother Nature. Human’s destruction to these habitats is much worse due to the fact that Mother Nature’s destruction is mostly temporary, while humans leave more of a lasting footprint on the habitats because of our persistence. (National Geographic, n.d.). Marine habitat destruction caused by humans are wetlands being filled for further development, runoff water which carries chemicals, pollutants, and wastes are pumped back into the water without…

    Next, it’s difficult to protect and conserve fish and other ocean creatures (compared to land animals) because unnoticed killings and or ways of bypassing protections. So, unnoticed killings happen because the earth is made up of more than 80% of water, which allows a lot of people to be able to boat out in the ocean and fish, kill fish, fin sharks and whales and so much more. People lie and hide what they are doing to coast guards and other police departments to stay out of jail or get their boat token and more. People bypass or go around protections like underwater nets or wall and or water barriers by cutting mainly to get in and get the precious endangered species. Also it’s hard to protect marine species because there are fishing competitions and millions of local fishers which are very difficult to stop because it such a large industry.…

    Mankind is poisoning the planet. Today, enough fossil fuels have been burned and enough forests have been chopped down to increase the highest concentration of carbon dioxide than any point in the past eight hundred millenniums. (528) In the article “The Acid Sea,” Elizabeth Kolbert wrote about how the polluted sea around Castello Aragonese provides us with a glimpse of our future oceans and how it interferes with the chemistry of the ocean. In the article “Our Oceans are Turning into Plastic … are You?,” Susan Casey discusses the negative effects plastic has on the environment. “The Acid Sea” and “Our Oceans are Turning into Plastic … are You?” did an excellent job with providing strong arguments and appeals to inform and persuade the reader that the world is deteriorating and reform is compulsory for the health of the planet.…

    The ocean is a great natural resource that must be protected from waste and pollution. Even though there have been great strides over the past several decades to reduce the amount of ocean pollution, more can and should be done. So as a team, we decided to tackle this ongoing issue and concern, in an effort to provide maybe a slightly different insight into a solution space. Our thought process centered around leveraging existing ideas/solutions, better and well informed education, and stricter government and federal…

    The relationship between humans and their environment is a topic that engenders much debate. Humans are intellectual. They can think, reason, feel and make deductions or hypothesis and seek to solve or prove their deductions or theories. The environment on the other hand is inanimate and exists by means of natural laws and principles that govern the universe. It cannot prevent man’s exploitations; it cannot take up arms and fight. However, in its own way, by natural laws, it makes efforts to purge and renew itself from the effects of man’s endeavors. Mangor (2002) argues that like the ocean that shapes coastal landforms, the coasts are dynamic aspects of the environment that are in constant change. Thus, by means of its natural processes such as sea level rise, waves and various phenomenon, erosion, accretion and reshaping of coasts, flooding and the creation of continental shelves it defends itself against man. A specific aspect of the environment that engenders conversation is the coastal landscape: its beauty, its purpose, its abuse, and its future.…

    American scientist Philippe Cousteau said, “Our oceans are facing innumerable threats from overfishing and pollution to ocean acidification and invasive/extinction of species.” This quote rings to our lives today in California because having over 50 beaches locally, we have seen most if not all of them in some manner polluted and mistreated. Simply, we love to visit our local beaches for the cool breeze and the overall view. The sense of “vacation” that draws us after a hard day’s work. We as humans however haven’t done our part to protect and keep our oceans clean, but instead to pollute and make our beaches endangered. Oceans are essential to life because it provides us with food, water and oxygen. Furthermore, it's a home for many species…

    Pollution of the world's oceans is quickly becoming a major problem on Earth. We know very little about the effect that pollution has on the oceans, but we continue to dispose off chemicals, sewage and garbage into it at an unprecedented rate. Most people likely do not even know what types of pollutants reach the oceans. There may be billions of people unconcerned about ocean pollution and hence this problem. Truly, the fish catch from the sea will tend to bio concentrate the pollutants to finally reach the humans.…
