Reading Passage
Genetic modification (GM) of food has been a subject of intense debate since its introduction in the 1990s. While proponents argue that GM crops can help address global food security issues, critics raise concerns about potential risks to human health and the environment. This controversy has sparked a wide-ranging discussion on the ethical implications of altering the genetic makeup of our food sources.
One of the primary ethical concerns surrounding GM food is the potential impact on human health. Although numerous studies have found no evidence of harm from consuming GM crops, some scientists and consumers remain skeptical. They argue that long-term effects are still unknown and that more research is needed to ensure the safety of these products. This uncertainty raises questions about the ethical responsibility of governments and corporations in introducing GM foods to the market.
Environmental impact is another significant ethical consideration. Proponents of GM crops claim that they can reduce the use of pesticides and increase crop yields, potentially reducing the environmental footprint of agriculture. However, critics worry about the potential for GM crops to cross-pollinate with non-GM plants, leading to unintended consequences in ecosystems. The loss of biodiversity is a particular concern, as GM crops could potentially outcompete native species.
The issue of food labeling also presents ethical challenges. Many consumers argue that they have a right to know whether the food they purchase contains GM ingredients. This has led to debates about transparency in the food industry and the extent to which companies should be required to disclose information about their products. Some countries have implemented mandatory labeling laws for GM foods, while others have resisted such measures.
The economic implications of GM food technology raise additional ethical questions. While GM crops may offer benefits such as increased yields and resistance to pests, there are concerns about the concentration of power in the hands of a few large biotechnology companies. Critics argue that this could lead to the exploitation of farmers and reduce food sovereignty, particularly in developing countries.
Animal welfare is another ethical consideration in the GM food debate. Some GM animals have been developed for increased productivity or disease resistance, but this raises questions about the moral status of these creatures and whether such modifications compromise their well-being. The potential for reducing animal suffering through genetic modification must be weighed against concerns about treating animals as mere commodities.
The precautionary principle is often invoked in discussions about GM food ethics. This principle suggests that when an action or policy has the potential to cause harm to human health or the environment, precautionary measures should be taken even if some cause-and-effect relationships are not fully established scientifically. Applying this principle to GM foods has led to calls for more rigorous testing and regulation before widespread adoption.
Religious and cultural perspectives add another layer to the ethical debate. Some religious groups object to genetic modification on the grounds that it interferes with divine creation. Cultural attitudes towards food and agriculture also play a role in shaping public opinion on GM foods, with some societies placing a high value on traditional farming methods and “natural” foods.
As the technology continues to advance, new ethical questions emerge. The development of gene-editing techniques like CRISPR has opened up new possibilities for precise genetic modifications, but also raises concerns about the potential for creating “designer foods” and the implications this might have for social equity and human identity.
In conclusion, the ethical implications of genetic modification in food are complex and multifaceted. They touch on fundamental issues of human health, environmental stewardship, economic justice, and the relationship between science and society. As we continue to grapple with these challenges, it is clear that ongoing dialogue and careful consideration of diverse perspectives will be essential in navigating the future of our food systems.

- What specific gene-editing technique is mentioned as opening up new possibilities for genetic modifications?
- According to the passage, what do some religious groups believe genetic modification interferes with?
Answer Key and Explanations
-
False
Explanation: The passage states that “numerous studies have found no evidence of harm,” but it does not claim that all studies have concluded GM foods are completely safe. -
True
Explanation: The passage explicitly mentions that “Some countries have implemented mandatory labeling laws for GM foods.” -
True
Explanation: The text directly states that the precautionary principle suggests taking precautionary measures “even if some cause-and-effect relationships are not fully established scientifically.” -
False
Explanation: The passage indicates that while CRISPR has opened new possibilities, it also “raises concerns about the potential for creating ‘designer foods'” and other implications. -
Not Given
Explanation: The passage mentions religious objections but does not specify whether these are based solely on scientific arguments or other factors. -
D
Explanation: The passage discusses health, environmental, and economic implications of GM foods, but does not mention effects on space exploration. -

Misinterpreting “Not Given”: Remember that “Not Given” means the information is neither confirmed nor denied in the passage. Don’t rely on outside knowledge or assumptions.
-
Overlooking qualifiers: Pay attention to words like “some,” “may,” and “could,” which indicate possibilities rather than certainties.
-
Mismatching headings: Ensure you understand the main idea of each paragraph before matching it with a heading.
-
Exceeding word limits: In short answer questions, stick strictly to the word limit given and use words directly from the passage.

Grammar Spotlight
Pay attention to the use of conditional structures in the passage, such as:
“GM crops could potentially outcompete native species.”
This type of conditional (using “could” + infinitive) is used to express possibility or potential outcomes. It’s common in academic writing when discussing hypothetical situations or potential consequences.
