For example, gravity is not a fact. Newton’s “theory of gravitation” was altered by Einstein who redefined gravity from a “force” to the “curvature of space-time.” The theories we accept also change with time: A neurologist won a Nobel Prize for inventing the frontal lobotomy! Now we consider the idea barbaric. The physicist who proposed the theory of continental drift was laughed out of scientific circles. Fifty years later, we accepted the theory of plate tectonics.

I am a scientist, a veterinarian and I love science. It gives us everything from ink to IMAX, but anyone who sits in a tower of scientific righteousness better check the foundation because it will crumble. Not only does evidence constantly change, it is riddled with economic and political bias.

If a Monsanto scientist says it is safe for us to eat herbicide-covered GMO food, is it true? Because 46 percent of dogs over the age of 10 has cancer and their food is full of GMO corn, a good scientist must wonder. Use basic reasoning – herbicides are poison and not safe to eat.

Regarding vaccines; in 1998, The Lancet published research implicating a link between autism and a measles vaccine. In 2010, this major medical journal admitted it was wrong. How can we trust the fickle finger of facts?

Immunizations prevent disease and save lives, no doubt. However, vaccine safety must improve. Fortunately, some toxic chemicals in vaccines are being eliminated. The FDA wants the mercury-containing preservative thimerosal removed because mercury levels in infants may exceed EPA recommendations and possibly cause neurodevelopmental disorders. If thimerosal is not safe for infants, what about a kitten? Yet veterinarians still use rabies vaccines with thimerosal.

The general public is wise to mistrust science, GMO foods and vaccines. When the consumer balks, the manufacturers listen. People demand safe food and medicines. Tell the scientists from the Pew poll to work on that.
