Under the sea

far more resistant to changes than we think. There have been many studies concerning the state of wildlife underwater after being subjects to change. Some of them reveal the destructions that happened under surface while a fair load also reports about how resistant the aquatic ecosystem can be. On top of this, a marine biologist, Jennifer O’Leary, reveals that many of the so called “bright spots” of the sea, the most sensitive beings, can persist through disturbances. One research the article mentions is on where it consisted of surveying 97 researchers on the conclusion of experiments they had done in on marine biology. In this group of individuals, 80% claimed to have witnessed organism resisting the changes. For example, we can observe how underwater corals, such as the ones from the coral reefs, have recovered up by 44% after having lost 90% in the past 12 years. It’s a great observation of the behaviour of the ecosystem because it allows us to study specific cases of resilience. Further analysis reports resilience is greatly impacted by removing “stress” out of the way of the organism, such as pollution. This paper puts emphasis in knowing that climate change is still significant, but proper care of the ecosystem can do good. (Balarama, 2017)

After reading the article, I think that the reason we are experiencing so much ecological issues globally is because we cannot seem to have the means to fix our mistakes (like pollutions). We saw that by removing pollution from the ocean we can make organism incredibly resilient to changed environment. So, if only we could be doing better work at taking care of the planet, maybe we could help nature become more resilient. It’s a pretty good idea considering it’s also for our own good.

I read this article because I am always curious to find out what kind of changes the underwater environment goes through in this era of human-created disturbances, in the forms of pollution, contamination, etc. I was surprised to find out that some marine ecosystems are very strong and have the capacity to withstand the effects of industrial human life and climate change. In a paper published in 2006 by Springer Science & Business Media, the author recognizes “that corals and coral communities possess effective mechanisms of adaptation and acclimation”, but remains skeptical of how coral populations can successfully continue to resist the increasing effects of climate change. (Nyström, 2006). No matter how strong and resistant an ecosystem is, its abilities are not limitless. It is unfortunately necessary and inevitable that we intervene, since we cannot rely on ecosystems to protect themselves as efficiently as they used to. In 2017, a paper was published detailing concrete plans of action that are being taken by the US Coral Reef Task Force to counteract the negative effects of climate change on the coral populations. (West, J. M. et Al, 2017) Scientists and experts from all over the US are working on a “climate-smart approach”, which are being adopted through the “Corals and Climate Adaptation Planning (CCAP) project”. (West, J. M. et Al, 2017) Hopefully, even in today’s climate change-denying US political administration, scientists and environmental activists will continue to fight for issues such as these and succeed in preserving the environment and minimizing the impact of poor government policies.
