this slide is about the effects of genetic engineering in humans and crops

2. Genetic engineering………...
Genetic engineering is the process that
uses the techniques of molecular cloning and
transformation to alter the structure and
Characteristics of genes
Genetic engineering is
about scientists
altering the 'recipes' for
making life
WHAT?!

3. What is Genetic Engineering used for?
Scientists uses it to knock out certain
genes from an organism to observe the
effects caused by those genes.
Manipulate the genes of
other organisms in order
to produce beneficial
products for
humans.

4. Is
genetic
engineering beneficial
to
humans?

5. Improves the lifestyles of
humans
• Better yield and quality of crops
• Microorganisms as pollution cleaners
 Production of super-crops
 Bioremediation of the polluted
environment

6. Production of crops of better yield & quality
Genetic engineering has helped to increase crop
productivity by introducing qualities such as
disease resistance and increased drought
tolerance to the crops
Genes from
naturally
drought-resistant
plants are used
to increase
drought
tolerance in
crop varieties

8. Farmers have been producing foods that have been
genetically altered to be more nutritious, delicious,
resistant to harmful pesticides and have the ability to
repel pests.
Plant life is changed to be more resilient to
insect and disease as well as have the help
of the microorganisms helping support it
and bringing it protein.
Wieczorek, A. (2003) Department of Tropical
Plant and Soil Sciences, transgenic
organisms can offer a range of benefits
above and beyond those that emerged from
innovations in traditional agricultural
biotechnology.
Production of crops of better yield & quality

9. Hmm…..

10. There are possible risks associated with
using transgenic crops in agriculture.
• Inadequate effort has been made to understand the
dangers in the use of transgenic crops
• Genetic engineering technology has the risk of
introducing allergens and toxins into safe foods.
• Transgenic crops might cross-pollinate with
related weeds, possibly resulting in “super
weeds” that become more difficult to control.
• It goes against religious values &
ethics

11. Inadequate effort has been made to understand the
dangers in the use of transgenic crops
Transgenic crops and their product in the United States
are extensively researched and reviewed
U.S. Department of Agriculture :
Has primary responsibility for
determining if a new product is
safe to grow.
U.S. Environmental Protection
Agency : Reviews the product for
potential impact on the
environment
U.S. Food and Drug
Administration : Is
concerned with
protecting the
consumer and has
final authority to
declare if a product is
safe to eat.

12. Genetic engineering has the risk of
introducing allergens & toxins into safe foods.
The Food and Drug
Administration (FDA) checks
to ensure that the levels of
naturally occurring allergens
in foods made from
transgenic organisms have
not significantly increased
above the natural range
found in conventional foods.
Transgenic technology is
also being used to remove
the allergens from peanuts,
one of most serious causes
of food allergy.

13. Transgenic crops might produce uncontrollable
‘super weeds’
Resistance to a specific herbicide
does not mean that the plant is
resistant to other herbicides, so
affected weeds could still be
controlled with other products.
Most crop plants have
significant limitations in their
growth and seed dispersal
habits that prevent them from
surviving long without
constant nurture by
humans, and they are thus
unlikely to thrive in the wild
as weeds.

14. Religious values & ethics
“Nature makes nothing without some end
in view, nothing to no purpose, it must be
that nature has made for the sake of man"
Aristotle
Since animals and plants
exist for human beings, our
behaviour towards them is not
governed by moral considerations.
Gen 1: 26-28."Increase & multiply & dominate the Earth".
At the same time we can
say that high tech
medicines involves
playing with God and
agriculture was started
by disrupting nature.

15. Any new technology has its set of
advantages and disadvantages.
However you cannot condemn a
beneficial technology because of the
possible misuse. Saying no to genetic
engineering would be like refusing to log
on to the Internet because you are afraid
your email account might get hacked. The
simple solution is to use the technology
with great caution.
