As I watch the TV news or read the paper or read science or news magazines, I constantly encounter stories that scream OVERPOPULATION. Often these are about damage to the environment, but there are many others about hunger, desperate poverty, deaths from preventable diseases, war, strife and other calamities.The July issue of Discover Magazine contained two articles about the ocean that support my concerns.
In “Better Planet - Garbage Patch” (click here for the web version) author Thomas M. Kostigen describes a trip to the Great Pacific Garbage Patch. This is an area in the Pacific Ocean where circular ocean currents trap some of the floating refuse of humans.
“Around and around: bottles, plastic bags, fishnets, clothing, lighters, and myriad other man-made items, held until they disintegrate, make their way to distant seas, or merely bob among the waves before washing up on someone’s beach.”
The second article is Ocean Reflux by Kathleen McAuliffe (click here for the web version). It has long been known that the oceans can sequester carbon dioxide as they naturally absorb excess carbon dioxide from the atmosphere. In fact, the oceans were seen as such a good place to store carbon dioxide, there have been suggestions that we pump liquid CO2 into the deepest parts of the ocean rather than let it disburse in the atmosphere and contribute to global warming.
Now new research has found that increasing levels of carbon dioxide in ocean water increases its acidity which may have profound effects such as destroying coral and many of the marine creatures at the bottom of the food chain. Among other problems this might cause, the loss of reefs and small ocean creatures could eventually threaten the planet’s fisheries.
I can’t begin to relay all the scientific details from these two articles, but you can read them yourself if you want more details.
Some scientist or researcher or politician will eventually tell you what we might do to mitigate or reverse these threats, but what you won’t hear them offer is a plan to reduce the number of people on the planet as a way to reduce the damage we are inflicting. Why is that?
Over Populated – Are We There Yet?
