What is a key application of genetic engineering in agriculture?

Improving environmental stress resistance is a key application of genetic engineering in agriculture because it directly addresses challenges that plants face in varying climates and conditions. By modifying the genetic makeup of crops, scientists can enhance their ability to withstand drought, salinity, extreme temperatures, and pests. This capability is crucial as it allows for the cultivation of crops in areas previously unsuitable for agriculture, improving food security and agricultural productivity in the face of changing global climates.

The emphasis on environmental resilience also means that genetically engineered plants can maintain yields despite adverse conditions, ultimately leading to more sustainable farming practices. By ensuring that crops can resist biotic and abiotic stresses, genetic engineering helps to reduce losses caused by environmental factors, which can be significant in agriculture. This is particularly relevant as climate change continues to pose risks to agricultural systems worldwide.

Other options, while they may be beneficial or relevant to advancements in agricultural practices, do not encapsulate the primary focus and utility of genetic engineering in contexts of pressing environmental issues.
