Overall Observations

Throughout the graphing of these data sets, I realized just how easily a species can change over just a handful of years. In the data sets given there were very few that ended even close to the levels they started off at. This proves that things can dramatically change depending on various factors that take place in their environment. The most influential example of this, for me, was seeing how the density of Krill in the Southern Ocean went from 91 Krill/ square M to just 3 Krill/ square M. This example shows how we have to be careful of all species in the world to ensure that we don't lose any because each species is important in their very own way and if depleted, could have a tremendous impact on the health of other environments and food chains.
