By the end of the day, the answer is simple.
Weed kills horses.
In a study published in the journal of the American Veterinary Medical Association, researchers showed that the herbicide Roundup can kill horses when they are exposed to Roundup.
In fact, the herbicides Roundup and 2,4-D (found in Agent Orange) are responsible for more deaths than car accidents, according to the study.
According to the scientists, horses exposed to 2,3-T, a form of glyphosate used in many herbicides, experienced increased mortality.
This is because the animals metabolize 2,5-D, which is much more toxic than glyphosate.
“The effects of the 2,2-T are so much more dangerous than glyphosate because it can damage the liver and kidneys, which causes death,” said Dr. David Kohn, an associate professor of veterinary medicine at the University of Minnesota, who was not involved in the study, in an interview with the Huffington Post.
Kohn and his colleagues at the U of M are the first to study glyphosate’s effects on horses.
They were able to identify glyphosate’s active ingredient, glyphosate-1, which has been found to be the main ingredient in glyphosate-resistant GMO corn, soybeans, cotton, and cottonseed.
They then used a system that measures the chemical’s effects in the animal’s system to determine the most likely cause of death.
The researchers found that glyphosate-2,4, or 2,6-D was the most dangerous of the active ingredients in the herbicidal.
The team said it was the main reason horses were dying, with the second-highest rates of liver and kidney damage.
According the researchers, these results suggest that horses exposed in this way may be more susceptible to liver and renal damage, and thus, die faster than those who do not.
They added that these effects may be particularly relevant to horses living in urban areas.
While the researchers did not have data on how many horses died from exposure to 2-4-d, they concluded that it could have been as high as 10 percent of the population.
The average life expectancy for a horse is about 30 to 40 years.
Kenneth Stolz, the lead author of the study and an associate veterinarian at the Minneapolis Veterinary Hospital, told the Huffington post that his team was not surprised by the results.
He said that horses were often exposed to glyphosate, and the herbivores’ immune systems were not equipped to handle it.
The U.S. Environmental Protection Agency (EPA) did not immediately respond to a request for comment.
The Environmental Working Group (EWG) also did not respond to requests for comment from The Huffington Post, and a spokesman for Monsanto did not return a request to comment.
According a statement on the organization’s website, glyphosate is a highly toxic substance.
Its chemical structure resembles a combination of acetylene and isopropanol.
The chemicals have been found in some chemicals used in cosmetics, like the synthetic surfactant and perfumes used by beauty salons.
The EPA does not regulate glyphosate, but glyphosate has been linked to a range of health problems in humans.
The herbicide has been shown to be a human carcinogen and has been banned in many countries.
