Answer:
Crops are now immune to many diseases and insects.
Explanation:
The constant advancement of science and technology within agriculture has been very beneficial to the better use of crops and to stimulate a better food supply, which has a beneficial impact not only on the lives of consumers, but also on the economy. One of the greatest benefits presented by this advance in science and technology is the ability to give agricultural crops resistance to pests and diseases. This is possible thanks to genetic engineering and advances in the study of agricultural entomology and microbiology, which have allowed scientists to manipulate plants to resist attack by harmful insects and microorganisms in agriculture. This resistance allows the plants to develop well and to produce products suitable for sale.
