Question

Ecosystems overlap. Mainly because the "borders" of them are grey areas blending into the next type of habitat. One constant is the weather. Now, the weather is "local" and "climate" is global. (This is why it's called Global Climate Change.) The climate between ecosystems brings different weather patterns and thus change that can affect the organisms present.

We polluted our seed's water to model the effects of Acid Rain. Did you know that the acid rain that affects the Pacific Northwest, where you as an organism are now living, comes from air pollution produced in Asia?

1) Why is it important to think about biosphere change being "global" rather than ecologically "local"?

Explanation / Answer

   Ecological disturbances brings mortality to organisms and changes their spatial patterning in the ecosystems they inhabit. These disturbance plays a significant role in shaping the structure of individual populations and the character of the whole ecosystem. Localized ecological systems are known to shift abruptly and irreversibly from one state to another when they are forced across critical thresholds.
   Long-lasting ecological disturbances causes stress to the natural ecosystems on a global range rather than a local scale. Let's take the example of the global impact on marine ecosystems due to ocean acidification. This stems from the absorption of carbon dioxide by seawater and the rise in average global near-surface air temperature, namely "the global warming". This disturbance has been found to increase drought frequency and severity, leading to modified patterns of ecosystem productivity and the geographic ranges of many fish species.
   As a result of over-fishing in 2010, there was a persistent global problem that is approximately 53% of the world’s fish stocks were fully exploited and 17% were over-exploited. A documentation by marine ecologists suggested that there were changes in the structure of fish populations and that of their prey which changed the structure of the ecosystems they inhabited.
