It is said that the overall population of the monarch butterfly had already declined about 80 percent over the last two decades, which means that there may not be that many butterflies left. This is a problem because it could lead to them becoming extinct -- soon.
According to Nathan Donley, a Kansas City local who personally witnessed the migration of monarch butterflies as a child and now sees the disastrous effects of pesticide use on their population, things aren't looking great for the insect species. "The ongoing decline foreshadows an ever-darkening picture for monarchs heading into a growing season where farmers are projected to use tens of millions of additional pounds of the drift-prone pesticide dicamba," he explained. "In 2017 alone, dicamba sprayed on crops genetically altered to resist it spurred thousands of reports of drift damage to more than 3 millions acres of nearby crops and untold stretches of forests and natural areas."
The pesticide makers themselves have made some projections, and they see that the potential for dicamba damage is about to increase even further – by about 100-fold -- thanks to U.S. farmers using it over the next two years alone on up to 60 million acres of farmland. That's an area that's larger than the state of Minnesota, which should help put things into perspective as to how the use of the pesticide can be so devastating.
Clearly, there needs to be a regulation on the use of these types of pesticides. Otherwise, it will ultimately lead to the untimely demise of monarch butterflies as well as other insects and animal species. (Related: Monarch butterfly decline being caused by GMO agriculture.)
In one analysis, it was shown that peer-reviewed research supported the idea that even just one percent of the so-called minimum dicamba application rate would be effective in reducing the size of milkweed as well as wither the leaves which caterpillars rely on for food. Dicamba is simply far too strong in its current state, and some experts say it could cause even more harm to milkweed than glyphosate, another form of pesticide.
Meanwhile, the Center for Biological Diversity's website shows an interactive mapping tool which illustrates that the actual timing and geographical distribution of dicamba has a coincidental link with the presence of monarch butterfly eggs and larva on milkweed.
Additionally, dicamba is also known as capable of harming other flowering plants which can provide nectar to adult butterflies during their travels to the South for the winter. In short, a check needs to be placed on its use, or else the world might end up seeing what kind of disastrous effects that losing the likes of monarch butterflies would have on the overall ecosystem.
