The most potent buzzwords in America today are "climate change," "green," and "sustainability."
They're all synonyms used by the left in order to gain more control over your life and tell you what to do and how to do it.
Now conservation is fine, and we are all pursuing good fishing practices, with a few examples from ignorant, selfish sportsmen. What I'm talking about is blatant misrepresentation or exaggeration of the facts.
Rip Cunningham wrote about the "higher acidity" in the ocean "as the atmosphere becomes more saturated with carbon dioxide." The concentration of atmospheric carbon dioxide is now around 390 parts per million.
This is 390/1,000,000 or 0.039%. It is entirely inappropriate to speak of "saturated" gas in our atmosphere except for water vapor. It is theoretically possible to have an atmosphere of 100% carbon dioxide.
Anthropogenic (manmade) carbon dioxide is estimated at a scant .05 parts per million annual increase. For comparison, carbon dioxide plus water vapor make up ~24,000 parts per million of the atmosphere. If you think that all your best efforts may, in 20 years, cut that annual increase from .05 ppm to .04 ppm and that will slow down "climate change" when the greenhouse gas mixture is ~26,000 parts (including methane, etc), then sell your car and don't go fishing ever again.
In the last 300 years, the pH of seawater has decreased from 8.05 to 8.025. As you probably know, pure water has a pH of 7.0 It will take 300 more years to reach a pH of 8.00.
I wouldn't worry too much about it. Clean up after yourself, help conserve our resources, and don't believe all the environmental hysteria. Al Gore, Prince Charles, and Barack Obama lecture to us little people while they fire up a whole lot more carbon dioxide than all of us on this forum combined.
... happens to match the 1000 year population increase graph.
But if that's too complicated, how about we put the whole thing in motion, go back 800,000 years, and include a few ice ages as well. We can even show the difference in fluctuations in the northern hemisphere where there are more people and landmass creating CO2, and less water to absorb the CO2
