Oceans and Fisheries and the effect of climate change

According to the article “Future fisheries can expect $10 billion revenue loss due to climate change” climate change has an influence on many high points. Global fisheries stand to lose approximately $10 billion of their annual revenue by 2050 if climate change continues unchecked, and countries that are most dependent on fisheries for food will be the hardest hit, finds new UBC research. A vast percentage of the globe is consuming fish everyday. Once again, if we will not control our consumption, with the help of the climate change, there are major chances more species will be instinct. As provided from UBC research, “climate change impacts such as rising temperatures and changes in ocean salinity, acidity and oxygen levels are expected to result in decreased catches.” Additionally, this will influence fish farming, as a result of climate change.



In my opinion, not only there will be damage in the ecosystem and the food chain, but this phenomenon will affect the economy of all countries at once. Moreover, it may all end up with a crisis that people from the 21st century are not ready for.

I chose to comment on your summary because I am very sensitive to climate change causing so many damages to the oceans and the fisheries. Fisheries are affected by ocean acidification, plastic and toxic pollution, overfishing. Climate change affects all of us, as occupants of the planet Earth. Flooding and storms show us just exactly how much weather and climate can affect our lives. We have nowhere to go for now and we have no choice than to preserve what we still have in order to survive. There is a reason to believe that some unknown amount of warming could cause a catastrophic release of methane currently locked in methane clathrates on the ocean bottom, greatly accelerating warming. The Oceans are slowly dying which in itself is a life ending event. Scientists have recently calculated that global warming has a significant probability of causing the mass extinction of the phytoplankton in the ocean that provides about 70% of the oxygen on earth. If this happens, it will lead to the extinction of all animal life on Earth, including humans. I am outraged that state fisheries management of basic human pollution of marine inshore habitat and loss of this habitat has been ignored in order to protect special fisheries interests. General overfishing of depleted fish stocks and shrimping bycatch are blatant abuses happening on fisheries.
