Science Lesson For Congressional Climate Change Deniers

With Senator James Inhofe set to be the chair of the Environment and Public Works Committee, now is the time for Americans to deliver a lesson to congressional climate change deniers. After all, Senator Inhoffe infamously stated climate change is ““the greatest hoax ever perpetrated on the American people.”

Amateurs are Key to Gathering and Interpreting Scientific Data

The greatest contributions to science are made by every day people who gather data. Without the data and observations made by amateurs, professional scientists are often left with insufficient data. Amateur contributions to scientific data are found in fields as varied as astronomy and the taxonomy of plants.

Keeping an eye on the sky requires millions of eyes. Amateur astronomers are thus vital, and their observations of phenomena such as exploding supernovas and meteorites are prime examples of their contributions. Volunteer astronomers even discovered a group of galaxies.

Taxonomy has a long tradition of laymen making crucial discoveries. In fact, a recent study shows that over 60 percent of new European species were found by amateurs. This number makes it difficult to underestimate the importance of public enthusiasts to the plant and animal sciences.

The list of important scientific knowledge gleaned from the work of non-scientists is long. After all, it does not take a PhD to observe, record, and relay data to fellow enthusiasts and professionals. Amateur storm spotters often save lives by giving timely information to emergency management officials. Moving forward, we must maintain cooperation between laymen and professionals for the betterment of science and the human race.

Some Pros and Cons of Genetically Modified Foods

Pros and Cons of Genetically Modified Crops

With a nickname like "Frankencrops", genetically modified (GM) foods may bring about images of B movies such as Attack of the Killer Tomatoes. After all, there couldn't be any good come from messing with the DNA of crops. The reality is not as clear as those on either side of the debate would have us believe.

About 75 percent of processed food produced in the U.S. has GM ingredients according to the University of Santa Clara's Dr. Margaret McLean, a former adviser to the California Senate Select Committee on Genetics.
What Are Genetically Modified Foods
Adding genes from another organism or rearranging them within a single organism results in GM plants. Hybridized crops are the result of cross-pollination, which happens in nature, or in controlled environments to yield an organism that has the best features of both parents. Hybridization is a form of genetic modification. However, when speaking of GM foods, agriculturalists generally mean genetically engineered (GE) or transgenic modified organisms.
GE organisms are those with genes rearranged within a single species, while transgenic are modified by taking a gene from one species and adding it to another.
Pros of GM Foods
Purposes of GM crops are things such as making them less attractive to damaging insects, increasing tolerance to herbicides---or "Round-Up ready"--, increasing nutrients, disease tolerance and producing crops better suited to converting to bio-fuels. There is evidence that conventionally produced GM crops are more resistant to certain harmful fungus than organically farmed produce.
A commonly used GE corn seed-known as Bt corn- was made to produce its' own pesticide that's affective against the European corn borer and other insects. Corn borer larvae can destroy entire fields.
The bananas, strawberries, green peppers, and other produce are grown from seeds that take longer to ripen, effectively increasing their shelf life. This reduces food waste.
Golden Rice increases the amount of vitamin A in the human body. This is particularly good for those who lack these vitamins in their diet.
Perhaps the most controversial forms of GM crops are "pharma-crops"-or crops grown to produce pharmaceuticals. Grown on smaller test plots for over a decade, agri-businesses want to produce these crops on a commercial scale. A USDA document states that from 1988 to 2005 their Biotechnology regulatory Service (BRS) approved 1,855 field tests for pharma-crops in Hawaii.
The Con's of GM Foods
The first attempt to make GM crops with an increased shelf life was a failure. These were tomatoes, put on the market in 1994. They had genes that increased resistance to antibiotics. Transference of this resistance to people, who consume the tomatoes, was a real concern, forcing the tomatoes off the market.
Dr. Margaret McLean in "The Future of Food..." points out the potential for introducing allergy-producing genes into unrelated foods is real and Syngenta has already lost a settlement for accidentally selling unapproved corn seeds to farmers. There's no telling what is in an unapproved seed.
Environmental cons of GM crops are not certain. Verlyn Klinkenborg, in a Yaleenvironment360 piece, states he is against them in part because "there is plenty of evidence to show that genetically modified fragments are turning up in places they're not wanted." Introducing these fragments into the environment may indeed produce malformations worthy of the "Frankencrop" label.
Negative Socioeconomic effects of patented, modified seeds are another con. The Food and Agricultural Organization (FAO) nicely lays out a particular concern:
Farmers fear that they might even have to pay for crop varieties bred from genetic material that originally came from their own fields when they buy seeds from companies holding patents on specific genetic modification "events".
Patented seeds are more expensive and GM seeds often are effective for only one season, making it so farmers must buy seed every year. This could further contribute to consolidation and the worldwide economic disparity.
My take
The problem with genetically modified food is not necessarily inherent in the technology but the political forces that allow for it to be used in culturally, economically, and environmentally damaging ways. The same structure that allows monopolistic corporations to own the world and skirt regulations until a disaster such as the BP gulf spill happens will facilitate environmental destruction from GM crops, even if it is preventable.

There may be no stopping agri-business from pursuing these technologies. The Union of Concerned Scientists has publicly denounced the coming "pharma-crop" revolution, with little effect on test plot approval. Organizations that care about the environment and social justice must not allow innate biases to get in the way of potentially sustainable technologies. At the same time, we must not be victims to a stacked deck and should pressure those who control these technologies to use them responsibly. This is a difficult task in any political environment.

Understand Sustainable Packaging Materials

When considering sustainable packaging materials, it is important to know the terminology. Advertising "green" products is big business. Consumers may get lost in catch phrases, and not understand what makes packaging environmentally friendly. The ability of packaging to be recycled is an essential element of eco friendly design. A good understanding of industry terms helps to avoid being misled. Read my latest about sustainable packaging to avoid being greenwashed.

Real Environmentalists Should Shut Up About Climate Change

Everyone knows Americans are skeptical of experts including scientists--and with good reason. While the basic physics of climate change is difficult to argue, the climate prediction models, even for most reasonably unbiased scientists, are closer to educated guesses than hard evidence. This is not disparaging the intelligence or competance of scientists employed by organizations such as NOAA, it's just a simple fact that the complexities of climate make any concrete predictions unreasonable. Scientists can't even agree on proper methods for obtaining the current avergage temperature of the Earth, let alone the temperature 50 years from now.

How do we--or do we--incorporate and interpolate ocean temperatures?
What about climate stations that have no universal standards throughout the world?
How about the climate station that just had a parking lot built next to it after 30 years of operation and is still taking readings from the same, now slightly heated, spot?

Hmmm...no wonder so much skepticism. The problem is scientists should not even make these predictions. As I said, the evidence behind the simple physics of greenhouse gasses is difficult to argue against,(though a few die-hards will contest even this) We should focus on the what carbon dioxide, methane and other greenhouse gasses do, not specific temperature predictions. And I'll say it again, those concerned about the environment should be shouting the seemingly endless string of negative environmental consequences of fossil fuels that are easily seen by everyone. The gulf oil spill is just one big example of this.

Local Ecological Knowledge Key to Sustainable Ecosystems

Combining local ecological knowledge with sound scientific method is the key to managing sustainable ecosystems. Scientists should not only make token gestures of obtaining this knowledge but use locals as part of a bottom up approach to their applicable research. Local ecological knowledge often saves researchers time and money through offering solid evidence of ecological functions that lead to better management strategies. Read more

Illegal Immigrants Say Take Our Jobs!

This is slightly off topic but the way I see it this is a sustainability issue. Illegal Mexican immgrants are saying legal United States residents would not do the agricultural jobs that they do. Uh...what! As kids almost all of us worked in the corn fields. Many of my relatives worked these jobs for long periods until...um they were no longer availaible due to a workforce arriving that is more easily taken advantage of. In case anyone reading did not know, a peso is still worth far less than a dollar. This means illegals can come to the States and work for a few months and live the majority of the rest of the year in Mexico on what they made.

I'm a college euducated American, doing OK financially, yet I took this challenge. I have no problem with legal immigrants in the U.S. but this is an insult to ALL legal residents, no matter their heritage. Americans need to be self sustainable and take back our lives from corporations, and big business who are willling to hire illegals and do anything they can to keep us busy so they can further entrench us into wave slave status!

I say take the challenge Americans and contribute to a really sustainable U.S. Let's just see if they hold up their end and contact me now.

See More discussion about this illegal immgrant innitiative.
UPDATE:

I got an email with a link to a website where I was told to put in Farmworker in the type of employemt field and do a search for every state in the U.S. Nothing available in my state. I guess no illegals are willing to give up their jobs in Indiana! I know there are plenty here.
