Selective Breeding and Genetic Engineering Essay Example
Genetic engineering:
Positive aspects
• CROPS:
• •Enhanced tastes and quality
• •Reduced maturation time
• •Increased nutrients
• •Improved resistance to diseases pests and herbicides.
• •New products and growing techniques
• ANIMALS
• •Increased resistance productivity, hardiness and feed efficiency.
• •Better yields of meat, eggs and milk
• •Improved animal health
• SOCIETY
• • increased food security for growing populations
Negative aspects
• CROPS:
• •Overuse of genetic engineering can have a large and very bad impact on generations and extinction of different species
• •Not only we are worried about the plant being modified but also by the farmer as the big laboratories that work on this issue usually create crops so they can benefit as much as possible from them. This could mean that they create crops that only last for one season. Or only get protected if you use their herbicides. Or were addicted to these
• ANIMALS
• •Mainly the problem is that animals GM to make our human life easier, are unable to retreat to their normal habitat, examples of this is: chickens that are afraid of light, sheep's and goats with shrunk legs.
Selective breeding:
Positive aspects
With selective breeding, the whole story changes. Selective breeding has one big difference from genetic engineering, and this is, there is no need to change any genes therefore even though GE and SB go to the same way “creating the most suitable organism in different environments for humans”.
PLANTS:
• •The genetics of the plants remain the same
• •The plant have less risk to be dangerous in some way as it has been done using an organised mutation
• •Plants will be “improved” and will remain same test
• •Increased nutrients
• •Improved resistance to diseases pests and herbicides.
• •New products and growing techniques
• ANIMALS
• •Better yields of meat, eggs and milk
• •Improved animal health
Negative aspects
PLANTS
• •SB is not as accurate
