Decline of Marine Ecosystems
There is a new study reporting that marine ecosystems can take thousands instead of hundreds of years to recover from climate change. Studies of invertebrate fossils show that recovery from climate change and seawater deoxygenation might take place on a millennial scale. Scientists studied a thirty-foot-long core sample of Pacific Ocean Seafloor coming from 3,400 to 16,100 years ago. It depicts what happened in the last major deglaciation, or climate warming. They focused on the study of complex organisms which provides a better understanding of how climate changes affects marine ecosystems. They found that during periods of below average oxygen levels fossils are nearly non-existent, and that it takes thousands of years for these ecosystems to recover from climate change. In the future scientists expect to see more of these low oxygen sea areas or dead zones with little to no life.
The ethical issue this article brings about is continuation of our rapidly changing climate. With the climate temperatures continuing to increase, there are more species and ecosystems that are disappearing. Taking to steps to prevent the decline of the world environments is crucial for not just marine life but all life on Earth. We will need to focus even more on preserving and reclaiming the environments we have otherwise our future generations will be unable to stop the rapidly increasing climate temperature.
Should we provide an even greater focus on the environment or should we continue with the way we are now?
