Humans and the Chlorophyll who Support Us

Look a bit familiar?

That’s because the top map is the same view of August’s chlorophyll concentrations in blue gradients from my last post. The new map shows the estimated population of people per country, with countries of larger populations showing red while countries of smaller populations are yellow. The correlation between the two might not seem apparent, until you realize that some of the center dark regions of the oceans that are lacking chlorophyll are located near areas with high populations. As suggested by my professor, the runoff or water pollution for these areas may be contributing to the lower levels of chlorophyll, but more information is needed. One thing is for sure, this correlation is more easily observed with colorful maps.
