Preventing Soil Erosion, but at what cost?

Genetically modified crops are being planted in farmlands at an accelerated rate. This is due to all of the supposed benefits associated with them. For example:

• Lower costs of production


• Fewer weeds


• More abundance and sustainable


• Less Soil erosion


• Cleaner Water


• Less carbon being emitted into the atmosphere

While all of these benefits are amazing in creating a lower polluted, more sustainable planet, we have to ask ourselves "what are we paying for this trade off?" There have been no conclusive studies as to the long term effects of consuming genetically modified foods. There need to be more tests conducted and more reports issued.
The population has been consuming genetically modified foods, sometimes without their knowledge, so we need to start the conversation of "is there a long term effect on humans who eat this food and if there is, is the trade off small enough to justify the continuation of planting these crops?"
Do you know how much of your food consumption contains genetically modified foods? I would love your opinion on this topic and potential ways to create more awareness in order to have a healthy life as well as a healthy planet.
