During the period of frequent tectonic activity of the earth, the new ocean basins around Africa, South America and Europe began to expand, creating new spaces. A large amount of carbon dioxide in the atmosphere reacted with photosynthetic organisms, and the dead organisms were then buried in seafloor sediments to form carbon-rich shales, and the carbon in the atmosphere was fixed, resulting in a decrease in the level of carbon dioxide in the atmosphere. Reducing Greenhouse Effect and lowering global temperatures have very serious consequences for marine life
Global warming can lead to an ecological crisis of marine life. Scientists have found that a similar crisis occurred in marine life during the period of global cooling 260000 years ago
scientists believe that the consequences of global cooling or warming are equally serious.
