EARTH AND LIFE SCIENCE Quarter 2 - BENEFITS AND RISKS OF USING GMOs

Summary

This lesson on genetic engineering explores its definition and applications, particularly in the context of genetically modified organisms (GMOs). It highlights the benefits, such as increased crop yields, reduced pesticide use, and advancements in medical treatments like vaccines and insulin production. However, it also addresses significant risks, including reduced genetic diversity, potential technological abuse, and complex legal issues arising from patenting. The importance of responsible use and ongoing research is emphasized to balance the advantages with the inherent risks, fostering a thoughtful discussion about the impact of genetic engineering on agriculture and health.

Q & A

What is genetic engineering?

Genetic engineering is the process of changing the DNA in living organisms to create something new through artificial manipulation, modification, and recombination of DNA or other nucleic acids.

What are GMOs?

Genetically Modified Organisms (GMOs) are organisms whose genetic material has been altered using genetic engineering techniques, resulting in traits that differ from those found in natural organisms.

What are some common crops that are genetically modified?

Common genetically modified crops include soybean, maize, cotton, canola, papaya, eggplant, potato, apple, soft flour, pineapple, and sugar cane.

What are the main benefits of using GMOs in agriculture?

The main benefits of GMOs include increased agricultural productivity, reduced use of pesticides, improved disease resistance in crops, and the ability to create crops that are better suited to survive harsh environmental conditions.

How does genetic engineering contribute to human health?

Genetic engineering contributes to human health by developing new medical treatments, such as vaccines, insulin, and hormone therapies, and by potentially curing genetic disorders through DNA manipulation.

What are some risks associated with GMOs?

Risks associated with GMOs include limited genetic diversity, potential technological abuse, legal issues related to patenting DNA, and the ongoing need for modifications as pathogens evolve.

What is recombinant DNA technology?

Recombinant DNA technology involves combining DNA from different sources, which can be used to improve crop varieties and produce medical treatments.

How do GMOs improve food safety?

GMOs improve food safety by reducing or eliminating the need for chemical pesticides, which can lead to safer agricultural practices and higher-quality food products.

What legal challenges do farmers face with GMOs?

Farmers face legal challenges related to patenting, especially if GMO seeds unintentionally spread to their land, leading to potential lawsuits and liabilities.

What is the significance of genetic diversity in relation to GMOs?

Genetic diversity is significant because a lack of diversity can make crops more susceptible to disease and pests, highlighting the importance of maintaining a wide variety of genetic traits in agriculture.
