"At the end of the day, it turned out that the size of the dead zones really doesn't seem to be the key thing for the extinction," Deutsch said. We can also support organizations doing amazing conservation work to bring endangered species back to a healthy, natural level. These natural events either take place over millions of years, or are extremely rare. "Very few marine organisms stayed in the same habitats they were living in it was either flee or perish," said second authorCurtis Deutsch, a UW associate professor of oceanography. So, once again, our best course of action is to leave nature alone as much as we possibly can, and the most effective way we can do this is to change our diet to one that is more plant-based. What caused Earth's biggest mass extinction? Long before dinosaurs, our planet was populated with plants and animals that were mostly obliterated after a series of massive volcanic eruptions in Siberia. "Since tropical organisms' metabolisms were already adapted to fairly warm, lower-oxygen conditions, they could move away from the tropics and find the same conditions somewhere else," Deutsch said.

WebAccording to many a prophet in the temple of science, biology has no permanent limitations. When habitats are destroyed, species can no longer access the resources they need to survive and may die out as a result. Urbanization has led to reduced physical activity and unhealthy nutrition. Many factors contribute when determining the manner of death, including the circumstances surrounding the death. These losses will, at best, take decades to reverse, resulting in a planet less able to support current and future generations. Communities are more susceptible to future land degradation as well as to socioeconomic and political forces due to the long-lasting effects of land degradation, such as soil erosion and contamination. According to data from the Centers for Disease Control and Prevention, strokes are the fourth leading cause of death for Americans 65 and older. The extinction of any species is an irreversible loss of part of the biological richness of the Earth.
