Build A Kinder Earth

Do you often wonder why more effort hasn’t been made towards restoring damaged ecosystems? Could it perhaps be because many feel the act is impossible to complete? Though you may have heard otherwise, restoration is a very plausible feat.

A recent analysis of 240 independent studies by researchers at the Yale School of Forestry and Environmental Sciences contains good news.  According to the researchers, most polluted or damaged ecosystems worldwide can recover within a lifetime if societies commit to their restoration.

Yale researchers have found that forest ecosystems recovered in 42 years on average, while ocean bottoms recovered in less than 10 years.  Ecosystems affected by damages such as invasive species  such as kudzu, mining, oil spills recovered dramatically with time frames as little as five years.  Typically ecosystems took a longer amount of time to recover from man-made disruptions than natural disturbances such as hurricanes, or tornados.

The Yale analysis focused on seven different ecosystem types, including marine, forest, terrestrial, freshwater and brackish in recovery from disturbances including agriculture, deforestation, eutrophication, invasive species, logging, mining, oil spills, overfishing, power plants and trawling and from the interactions of those disturbances. Major natural disturbances, including hurricanes and cyclones were also explored.

The researchers defined the recovery of each of the variables in terms of the time it took for them to return to their pre-disturbance state.

Naysayers may persist that it will take centuries for an ecosystem to be restored, however, this anaylsis asserts otherwise.  Though the study may not be entirely accurate in it’s determining of an ecosystem’s pre-disturbance state, we can still conclude from it that a very noticable difference can be achieved by major efforts towards restoration. So, as of now there remains no excuse for not actively persuing restoration. Rebuilding ecosystems is a plausible feat that will be achieved with the efforts and support of a society.
