What is a potential disadvantage of agricultural biotechnology?

The potential disadvantage of agricultural biotechnology highlighted here is the reduced biodiversity due to the dominance of modified crops. When genetically modified (GM) crops are adopted widely, there is often a shift away from traditional varieties. This can lead to monoculture practices, where a single crop species or variety is cultivated over a large area. Monocultures can diminish genetic diversity in agriculture, making ecosystems more vulnerable to pests, diseases, and environmental changes.

Furthermore, the reliance on a few GM crops can put pressure on local agricultural systems and eliminate the variety of plants that are crucial for maintaining ecological balance and resilience. This reduction in biodiversity can have far-reaching effects on food systems, ecosystem services, and the ability of the environment to respond to challenges, such as climate change.

On the other hand, the other options do not accurately represent disadvantages of agricultural biotechnology. Increased food security, while a potential advantage, is not a disadvantage. The complete eradication of pests is not a guarantee of biotechnology, as complete eradication can disrupt ecosystems. Lastly, biotechnology often aims to develop more efficient farming practices, which may actually reduce the labor required rather than increase it.
