Ethical Issues
Associated with
GMOs
ETHICAL
ISSUES
GEC108
9.5
not for circulation
1. Safety
The safety of GMOs has been under much debate and
concern. It is a common fear that genetic modification
may result in unintended consequences, such as the
creation of new allergens or toxins, the spread of
modified genes to wid relatives, or the deveopment of
antibiotic- resistant bacteria.
ETHICAL
ISSUES
GEC108
9.5

2. Health
There exists concerns about potential health risks
associated with it. Some studies suggested that GMOs
may cause allergies or other health effects, although
there’s a lack of concrete evidence to support these.
Additionally, concerns that GMOs msy contribute to
the development of new diseases or the spread of any
existing diseases.
ETHICAL
ISSUES
GEC108
9.5
not for circulation
3. Environment
The release of GMOs into the environment has the
potentialto cause ecological damage. For example, a
common fear is that genetically modified crops may
cross-breed with any wild relatives, which results in
the spread of modified genes and the creation of
invasive species. Additionally, concern that GMOs
negatively impact ecosystems by reducing biodiversity
and disrupting food webs.
ETHICAL
ISSUES
GEC108

not for circulation
4. Patents and Access to
Seeds
The issue of patents and access to seeds is another
ethical issues associated with GMOs. Many
corporations hold patents on genetically modified
seeds, which can make it difficult for farmers to access
the seeds they need to grow crops. This has led to
cerns about corporate control of the food supply and
the impact this may have on farmers and consumers.
ETHICAL
ISSUES
GEC108

5. Ownership of Life
The idea of manipulating the genetic makeup of living
organisms raises ethical questiond about the ownership
of life. Some argue that it is unethical to manipulate
the genetic material of living organisms for
commercial purposes, while others believe that genetic
modification is a necessary tool for improving the
quality of life for people around the world.

ISSUES

6. Public Perception
Despite the fact that there are many potential benefits
of GMOs, many of us wary of them due to concerns
about their safety and potential impact on the
environment and our own health. So, there’s an
absolute need for public education and awareness
about the benefits and risks of GMOs to help mitigate
these concerns.

INTER-
RELATION
Interrelatedness of Society,
Environment, and Health
Health of individuals and communities is directly impacted by the
environmental conditions in which they live. This include factors such as
access to clean water, air, and foods. So, if biodiversity will be lost or
destroyed it will cause widespread of diseases which will be a threat to
human health.
On the other hand, societies have the capability to create and follow rules
and policies to protect and conserve the nature. If nature is being
conserved, humans will benefit to it, most especially in terms of health, in
a way that humans can acquire clean sources of living. Also, richness in
biodiversity will promote economic development.

10.1
What is Climate Change?
⚫ It refers to the long- term shifts of temperature and
weather patterns in a given region. These shifts result from
various natural processes, but this term is used associated
with human-induced climate change.
⚫ Also used interchangeably with the term global
warming.

DEFINITION
GEC108
10.2
It refers to the rise of the
average temperature of the
Earth which persists over a
decade or longer.
The main cause of climate
change or global warming
is the high concentration of
greenhouse gases which
leads to the what we call
greenhouse effect.

Greenhouse Gases
⚫These are the gases in the atmosphere that traps
heat.
⚫They naturally occur in the world but just
enhanced by human activities.
⚫If there’s high concentration these gases in the
atmosphere, it leads to increased temperature of
the Earth, which will be the reason of having
climate change.

  • 50. ETHICAL ISSUES GEC108 9.5 not for circulation 1. Safety The safety of GMOs has been under much debate and concern. It is a common fear that genetic modification may result in unintended consequences, such as the creation of new allergens or toxins, the spread of modified genes to wid relatives, or the deveopment of antibiotic- resistant bacteria.
  • 51. ETHICAL ISSUES GEC108 9.5 not for circulation 2. Health There exists concerns about potential health risks associated with it. Some studies suggested that GMOs may cause allergies or other health effects, although there’s a lack of concrete evidence to support these. Additionally, concerns that GMOs msy contribute to the development of new diseases or the spread of any existing diseases.
  • 52. ETHICAL ISSUES GEC108 9.5 not for circulation 3. Environment The release of GMOs into the environment has the potentialto cause ecological damage. For example, a common fear is that genetically modified crops may cross-breed with any wild relatives, which results in the spread of modified genes and the creation of invasive species. Additionally, concern that GMOs negatively impact ecosystems by reducing biodiversity and disrupting food webs.
  • 53. ETHICAL ISSUES GEC108 9.5 not for circulation 4. Patents and Access to Seeds The issue of patents and access to seeds is another ethical issues associated with GMOs. Many corporations hold patents on genetically modified seeds, which can make it difficult for farmers to access the seeds they need to grow crops. This has led to cerns about corporate control of the food supply and the impact this may have on farmers and consumers.
  • 54. ETHICAL ISSUES GEC108 9.5 not for circulation 5. Ownership of Life The idea of manipulating the genetic makeup of living organisms raises ethical questiond about the ownership of life. Some argue that it is unethical to manipulate the genetic material of living organisms for commercial purposes, while others believe that genetic modification is a necessary tool for improving the quality of life for people around the world.
  • 55. ETHICAL ISSUES GEC108 9.5 not for circulation 6. Public Perception Despite the fact that there are many potential benefits of GMOs, many of us wary of them due to concerns about their safety and potential impact on the environment and our own health. So, there’s an absolute need for public education and awareness about the benefits and risks of GMOs to help mitigate these concerns.

This include factors such as access to clean water, air, and foods. So, if biodiversity will be lost or destroyed it will cause widespread of diseases which will be a threat to human health. On the other hand, societies have the capability to create and follow rules and policies to protect and conserve the nature. If nature is being conserved, humans will benefit to it, most especially in terms of health, in a way that humans can acquire clean sources of living.
