Final answer:
Increased use of glyphosate with glyphosate-resistant crops may lead to the development of herbicide-resistant 'superweeds', alter ecosystems, and have implications for human health.
Step-by-step explanation:
A potential problem from the increased planting of genetically modified glyphosate-resistant crops alongside heightened glyphosate use is the emergence of herbicide-resistant 'superweeds'. These are weeds that evolve resistance to glyphosate much like bacteria develop antibiotic resistance. This can result in a greater need for alternative weed control methods or stronger herbicides, potentially leading to unintended environmental impacts and human health concerns. Furthermore, the genetic engineering of crops can impact other organisms and ecosystems.
While genetically engineered (GE) crops such as 'Roundup Ready' have been beneficial in reducing agricultural loss and pesticide use, they have not significantly advanced crop yields compared to non-GE crops. Heavy reliance on a single herbicide can lead to biodiversity loss and affect the ecological balance. Concerns also remain about potential risks associated with consuming GM foods, such as the creation of novel allergens and unknown long-term effects. The use of glyphosate and glyphosate-resistant crops also poses ecological implications by potentially harming non-target species and affecting soil health.
