6) A con of GMOs is that

they are creating herbicide tolerant crops.
there is higher crop production.
they require fewer materials to grow crops
there is inefficient research to know the long term impacts they have.

Potential environmental risks associated with GMOs include the development of herbicide-resistant weeds, the unintentional harm to non-target organisms, and the disruption of ecosystems. Additionally, the long-term health impacts of consuming GMOs are still not fully understood, and there is concern about the potential for allergenic reactions or other health issues. Overall, the lack of thorough research and understanding of the full effects of GMOs is a significant drawback.
