Earth is the composition of many different systems working together to create our biosphere and planet. These systems have an impact on humans, and humans have an impact on them. Because of this, it is important for us to understand these systems as well as their relationship with each other.
The following are some important Earth systems.
If these systems are not healthy and balanced, ecosystems cannot thrive, which will inevitably result in negative impacts to the quality of life of human beings.
As mentioned before, life on Earth depends on a specific balance in synergy between Earth systems. If one system or piece is affected, over time, it will impact the whole and possibly create significant challenges to life. Life on Earth could be significantly altered if the following are impacted:
IN CONTEXT
Consider what might happen if the balance in just one of these Earth systems tips. Suppose that the concentration of ozone in our atmosphere drops significantly, perhaps because of human air pollutants, such as aerosols, or simply because of natural causes. As the ozone layer thins, UV radiation reaching Earth's surface will increase. This could lead to genetic mutation, increased cancer levels, and even extinction of many species, including humans.
In addition, the increased radiation reaching Earth will tip the balance in Earth's temperature, causing it to heat up. Increased temperatures on Earth will make survival harder for species that have adapted to colder temperature ranges.
Then, as the average global temperature rises, other chain reactions will occur. Ice caps and glaciers will melt faster, reducing the availability of freshwater. Ocean temperatures will heat up and release more carbon dioxide into the atmosphere because oceans are carbon sinks, which will then lead to further rises in average global temperature. This process will continue setting off more and more chain reactions, which is why keeping the balance in our systems is so important.
