GLOBAL CLIMATE CHANGE & ITS LINK TO SOIL ORGANISMS
When people think of the consequences of global warming, most jump to the melting ice caps and death of beloved polar bears. We know that as our Earth undergoes climate change, it’s adversely affecting the ecological balance in complex ways. For the first time, however, a study done at the University of California Berkley, has linked climate change to the downfall of microbial species that are considered essential to ecological systems. Previous studies have identified the use of chemicals as harmful for soil organisms, insects, and birds, but never has climate change been pinpointed as a threat to these species.
The study states that “models predict that up to 30% of parasitic worms are committed to extinction, driven by a combination of direct and indirect pressures.” With this, species that are adapting to the climate change will allow them to “invade and replace” native organisms resulting in unpredictable, but most likely negative consequences.
Dr. Colin Carlson is the lead author of the study and estimates that we will see a huge extinction rate within the soil organisms as time and climate change continues. He blames this effect on the loss of habitat and the implications of trying to coexist. The end result of this could be detrimental to the human species, requiring lively soil to live.
Carlson explains that the effect of climate change on soil organisms has gone unnoticed for so long because our research focuses on the impact of the change on animals like vertebrates. Most people see microbial organisms as pests, rather than a crucial part of the ecological system. Since the modernization of agriculture, we have seen soil as a medium for holding plants, as Jenny Hopkins, author of “Can American Soil Be Brought Back To Life”, likes to put it.
