Background:

Genetically engineered crops are increasingly adopted in the US.
Bacillus thuringiensis (Bt) produces an endotoxin that acts as a natural pesticide.
Traditional chemical pesticides pose environmental and economic challenges.

Purpose of the Study:

To highlight the role of transgenic pest-resistant crops in modern agriculture.
To present Bt crops as a sustainable alternative to chemical pesticides.
To discuss the potential of these crops in addressing global food security.

Main Methods:

Cultivation of genetically modified corn, cotton, and potatoes engineered to produce Bt endotoxin.
Monitoring of pest resistance and crop yield.

Economic and environmental impact assessment compared to conventional methods.

Main Results:

Approximately 30 million acres of US farmland are planted with Bt crops.
Bt crops provide targeted pest control, reducing the need for chemical insecticides.
These crops offer a cost-effective solution for farmers.

Conclusions:

Transgenic Bt crops represent a significant advancement in pest management.
They offer a sustainable and economically viable strategy for increasing crop yields.
Bt technology contributes to feeding a growing global population with reduced environmental impact.
