2-Minute Revision

Ethical issues in biotechnology are critical as they address the moral, social, and legal implications of manipulating life. Bioethics provides a framework for responsible innovation, guided by principles like autonomy, beneficence, non-maleficence, and justice.

Key concerns include the safety of genetically modified organisms (GMOs) for the environment and human health, and the profound ethical dilemmas surrounding human genetic engineering, especially germline therapy which involves heritable changes.

In India, the Genetic Engineering Approval Committee (GEAC) regulates genetically engineered organisms, ensuring safety and ethical compliance before their release. Intellectual property issues are also central, with biopatents granting exclusive rights over biological inventions, and biopiracy representing the unethical appropriation of traditional knowledge and biological resources without fair compensation, as seen in cases like Neem and Basmati rice.

Understanding these concepts is vital for NEET.

Biotechnology's power to alter life necessitates careful ethical consideration, a field known as bioethics. This discipline helps navigate the moral landscape, ensuring scientific progress is responsible. Core ethical principles include autonomy (respecting individual choice), beneficence (doing good), non-maleficence (avoiding harm), and justice (fairness).

Major ethical dilemmas arise from:

1
Genetic Engineering — Somatic gene therapy (non-heritable changes) is generally accepted, but germline gene therapy (heritable changes affecting future generations) is highly controversial due to concerns about altering the human gene pool and 'designer babies'.
2
GMOs — Concerns include environmental impact (cross-pollination, biodiversity loss), food safety (long-term effects), and socio-economic issues (corporate control, farmer dependency).
3
Cloning — Therapeutic cloning (for stem cells) is debated due to embryo destruction, while reproductive cloning (creating a genetic copy) is widely condemned.

India's regulatory body, the Genetic Engineering Approval Committee (GEAC), under the Ministry of Environment, Forest and Climate Change, plays a crucial role. It approves large-scale field trials and commercial release of genetically engineered organisms (GEOs), assessing their environmental and health safety.

Intellectual property is another key area:

Biopatents — grant exclusive rights over biological inventions (e.g., genes, GM crops). While incentivizing innovation, they raise ethical questions about 'owning' life and restricting access.
Biopiracy — is the unethical appropriation of traditional knowledge and biological resources without consent or compensation. Classic examples include the patenting attempts on Neem's fungicidal properties, Turmeric's wound-healing properties, and Basmati rice, all of which were traditionally known and used in India. These cases highlight the need for equitable benefit sharing and protection of indigenous knowledge.

Example: Biopiracy of Turmeric

Traditional knowledge in India recognized turmeric's wound-healing properties. A US university patented this use. India successfully challenged the patent, demonstrating prior art through ancient texts, leading to its revocation. This exemplifies how traditional knowledge can be exploited without proper recognition, underscoring the importance of international agreements like the Convention on Biological Diversity (CBD) and the Nagoya Protocol.

Prelims Revision Notes

Ethical Issues in Biotechnology: NEET Revision Notes

1. Bioethics:

Definition: — The study of ethical, social, and legal issues arising from advances in biology and medicine.
Purpose: — To guide responsible scientific practice, ensuring human dignity, environmental protection, and social justice.
Core Principles:

* Autonomy: Respecting individual's right to make informed decisions. * Beneficence: Acting to benefit others. * Non-maleficence: Avoiding harm. * Justice: Fair distribution of benefits and burdens.

2. Genetic Engineering & Gene Therapy:

Somatic Gene Therapy: — Alters genes in non-reproductive (somatic) cells. Changes are *not heritable*. Generally less controversial.
Germline Gene Therapy: — Alters genes in reproductive (germ) cells or early embryos. Changes *are heritable* and passed to future generations. Highly controversial due to permanent alteration of human gene pool, 'designer baby' concerns, and unforeseen long-term effects.
CRISPR-Cas9: — A powerful gene-editing tool, intensifying debates on germline editing due to its precision and ease of use.

3. Genetically Modified Organisms (GMOs) & Agriculture:

Concerns:

* Environmental: Cross-pollination with wild relatives ('superweeds'), impact on biodiversity, harm to non-target organisms. * Food Safety: Potential allergenicity, toxicity, long-term health effects (though approved GM foods are generally considered safe). * Socio-economic: Farmer dependency on multinational corporations, seed monopolies, impact on traditional farming.

4. Regulatory Body in India: Genetic Engineering Approval Committee (GEAC)

Ministry: — Under the Ministry of Environment, Forest and Climate Change.
Role: — Apex body for approval of activities involving genetically engineered organisms (GEOs) and products.
Functions:

* Approves large-scale field trials of GM crops. * Approves commercial release of GM crops/products. * Assesses environmental risks of GEOs. * Evaluates safety for human and animal consumption. * Monitors environmental impact.

5. Intellectual Property Rights:

Biopatent:

* Definition: Patent granted for biological entities (genes, proteins, microorganisms, GM organisms) or biotechnological processes. * Ethical Issues: Ownership of life, restricted access to essential technologies, potential for patenting traditional knowledge.

Biopiracy:

* Definition: Unauthorized appropriation and commercial exploitation of traditional knowledge and biological resources without fair compensation or prior informed consent. * Examples: * Neem: Fungicidal properties traditionally known in India; patent challenged and revoked.

* Turmeric: Wound-healing properties traditionally known in India; patent challenged and revoked. * Basmati Rice: Traditional Indian aromatic rice; US company attempted to patent, leading to partial revocation.

* International Efforts: Convention on Biological Diversity (CBD) and Nagoya Protocol aim to ensure equitable benefit sharing.
