1. Explore - Understanding GMOs and Their Impact
In this section, students develop a foundational understanding of genetically modified organisms (GMOs), how they are created, and why their impact can be complex. The Explore phase introduces key biological and biotechnological concepts needed to understand genetic modification before engaging in modelling, AR-based analysis, and creative activities later in the unit.
1.5 Potential Risks and Concerns
GMOs also raise valid concerns requiring careful evaluation, supported by ongoing ecological and social research:
- Effects on biodiversity (e.g., gene flow to wild relatives, herbicide-resistant "superweeds" documented since 2000s; non-target insect impacts under investigation) (source: https://www.science.org/doi/10.1126/science.ado9340).
- Potential gene transfer to non-target organisms (horizontal gene transfer; rare but documented in laboratory conditions).
- Long-term environmental impacts (soil microbial communities, effects on non-target insects such as monarch butterflies—debated since 1999 study, reassessed 2010–2020) (source: https://ecoservantsproject.org/genetically-modified-organisms-gmos-and-the-environment-impacts-benefits-and-concerns/).
- Ethical, social, and economic considerations:
- Farmer dependency on proprietary seeds and licensing agreements.
- Labeling regulations and consumer acceptance (varies by region).
- Equitable access to GM technologies in developing countries.
- Patent ownership and intellectual property concerns.
Understanding GMOs therefore requires systems thinking, where biological, environmental, and societal factors are considered together rather than in isolation.
Watch the video
To encourage critical thinking and discussion, students are invited to watch a short video presenting different perspectives on genetically modified organisms. The video highlights why the impact of GMOs can be complex and context-dependent, supporting informed analysis rather than simple “for or against” positions. This resource prepares learners for AR-based scenario analysis and decision-making activities in the following phases.
