Oxygen Depletion Zones In Tropical Oceans Expanding, Maybe Due To Global Warming
ScienceDaily (May 2, 2008) — Scientists confirm computer model predictions that oxygen-depleted zones in tropical oceans are expanding, possibly because of climate change. An international team of physical oceanographers including a researcher from Scripps Institution of Oceanography at UC San Diego has discovered that oxygen-poor regions of tropical oceans are expanding as the oceans warm, limiting the areas in which predatory fishes and other marine organisms can live or enter in search of food

The researchers found through analysis of a database of ocean oxygen measurements that levels in tropical oceans at a depth of 300 to 700 meters (985 to 2,300 feet) have declined during the past 50 years. The ecological impacts of this increase could have substantial biological and economical consequences.
Now, for your specific questions. First let me say that I wouldn't be too
worried yet, especially about the O2. The concentration of oxygen in the
atmosphere is greater than the human lung's capacity to remove it. When
you exhale, you release not only CO2 and N2 but a significant portion of
the O2 you just breathed in. Although the process is concentration driven
(ie the higher the O2 concentration, the more readily O2 is absorbed into
the blood stream) I don't believe that levels have gotten low
enough to cause difficulty breating. Secondly, O2 is a constantly
renewable resource. As long as there are plants living on this earth there
will be production of O2 - and by plants I mean not only trees and grass
and other terrestrial species, but also all the photosynthesizing aquatic
organisms. Often people don't realize what a HUGE part these creatures
play in the global cycling of all the most important elements. In fact,
some scientists believe that deforestation in certain areas of the world
and the resulting increases in CO2 will stimulate productivity in other
areas of the world including the oceans (note: this is one theory of many
and I want to be clear that I'm not trying to endorse one idea over
another - frankly, I'm not an expert on this topic and can't give you a
fair evaluation of all the current theories).

Well, you know, there are a lot of things that we wait until the last minute to do anything about. Look at the fuel problem now. We are just now coming o a common consensus that an alternative needs to be developed. It has been an issue for the last 30-40 years.

Oh.I agree. I just think tht it is unnecessary. I think that there are things we can do as inhabitants to prevent such measures being taken.
