High CO2 creates 'hollow' plants; extra growth is in sugars/starches

To The Daily Sun,

One of the most popular claims of climate change deniers is "CO2 is plant food". Attached to this will always be claims about how greenhouses grow bigger plants so more CO2 must be good for humans. This is an argument from ignorance (or deceit) because bigger plants isn't all you get. Worldwide field studies and controlled climate experiments have turned up some compelling data that can't be ignored.

High levels of CO2 create hollow plants.[1] By hollow I mean the extra growth is in sugars and starches, but there is a significant loss in the content of proteins and important minerals such as iron and zinc. Almost 3 billion people rely on a variety of crops for their nutrition and some of these such as wheat are hit by significant losses in vital nutrients. Studies have even shown that our present crops have less nutrition than crops grown in pre-industrial times. According to the National Institute of Health, "Iron deficiency ranked ninth among 26 risk factors included in the global burden of disease study, and accounted for 841,000 deaths and 35,057,000 disability adjusted life years lost. Large sections of populations in Africa and Asia are at risk of dietary zinc deficiency and resulting high rates of stunting."[2] Since 2 billion people are deficient in zinc and 1 billion have iron-deficiency anemia, why on Earth would anyone favor hollow food with less iron and zinc?[3]

On top of this is the problem of soil moisture evaporation which will increase in a warmer world. Drier soil due to higher evaporation rates will also create growing problems. While growing may improve in far northern latitudes, heat-related soil evaporation will not only stress plants, but whatever you get will have less nutritional value. High levels of CO2 also favors weeds over crops and trees.

Another growing problem presently is the increased range of insect pests and plant diseases. Warming has already caused important changes in species diversity and distribution.[4] One example is the destruction wrought on forests in North America by the Pine Bore Beetle which has significantly extended its range northward in the last century. With a changed environment, natural selection may also favor bigger more voracious insects. Insect borne diseases such as Malaria and Dengue are also likely to increase.

N.H. population under 18 declined 5% last year. Want to know why?

To The Daily Sun,

The United States used to be the home of manufacturing, innovation and technology. The best universities were here, the most patents, trademarks and copyrights came from America. Attainments in university education, basic research and intellectual property in America are now slightly less than on par with those of the EU ... and China is gaining ground. Something has changed and it is time to wake up and smell the coffee.

America has driven much manufacturing from our shores. We were sold the idea that the next thing coming was intellectual property, where we would lead the way ... so we did not need all that dirty manufacturing. Well, intellectual property does drive economic growth. But it drives economic growth only to the extent that business can use it to create value-added products. That means being brilliant is wonderful, but if you don't build something others will buy because it saves them time, makes life easier or better, or allows them to make more money ... you are brilliant but you are also very, very hungry.

One factor that is important to business's ability to drive productivity through innovation is a low corporate tax rate. In Europe the corporate tax rate is about 21 percent compared to about 40 percent in the United States. And then there's New Hampshire, where the governor has vetoed the state budget because even though the corporate tax burden is well in excess of the national average, she believes it is only fair to have that much or more taxation on business because ...

Want to know why the population of those under 18 in New Hampshire declined 5 percent last year? Want to know why the working age population in New Hampshire declined 1 percent last year? Here's a clue. If there aren't enough good-paying jobs to attract and retain people good people ... the population is going to go down. It is a basic rule of economies everywhere. People like to eat, they like nice homes, vacations, benefits and comfortable thoughts about their children's futures.

You know what happens when the population goes down? There is less spending, and tax revenues go down. If you just keep raising the tax rate to keep government revenues level or rising what happens is you continue driving away more businesses and you prevent new businesses from starting or coming here ... which continues the downward population spiral. And we elected this economic Bozo to be the chief executive of the state. Maggie Hassan a the perfect illustration of the Peter Principle.
