Answer:
advantage
principles that have been practiced for generations.
Humans have been manipulating plant and animal life since the beginning of our history. That is how we have so many different types of dogs, for example, or have access to different types of crops. Genetic engineering just increases the speed at which this progress can occur. Selective cross-breeding, based on specific traits, that work with similar traits in other species, is how we’ve achieved results. DNA insertion allows us to take this concept to new levels.
2. It makes agricultural practices much safer.
Before genetic engineering, farmers would often use heavy amounts of herbicides or pesticides to maximize their yields. Before herbicides and pesticides were invented, workers spent countless hours in the fields, often without skin protection, removing threats by hand. With modern scientific practices, we can reduce, if not eliminate, the need for anything to be applied to crops. That makes the work safer, creates healthier soils, and reduces the risks of groundwater contamination all at the same time.
3. It creates greater yields.
Workers have used pesticides and herbicides to maximize yields. We can also use genetic engineering to create larger yields from our crops. We can manipulate the DNA of plants to create more fruits per tree or more vegetables per fine. A larger yield means more profits for the agricultural worker, which means more innovation in this sector can be funded. Greater yields also create the potential for new products, such as ethanol from sugarcane or corn, because we’ve created enough food for society and still have leftover products.
disadvantage
1. It is a technology that can be easily abused.
We currently have laws and treaties in place to prevent genetic engineering abuse. That doesn’t mean it won’t ever happen. The reality of genetic engineering is that DNA insertion could be used to create severe problems for certain groups of people. Imagine that someone is allergic to shellfish. Someone could insert shellfish DNA into a regular crop, like corn. The person with the allergy would eat the corn and potentially have an allergic reaction trigger because of it. Over time, we could also take the approach we have to altering plants and animals to altering humans. If done, the consequences to our society would be numerous and unpredictable.
2. It is a process that can be copyrighted in the United States.
The judiciary in the United States has ruled that genetically engineered DNA sequences can be patented. That makes it more profitable for organizations to study DNA manipulation instead of working for the general good of humanity. Although this makes new plants or animals possible with self-sustaining revenues, it also means fewer people are studying human DNA sequences to seek out health benefits simply because there isn’t as much profit to the practice.
3. It creates difficult legal liabilities with unintended consequences.
It isn’t just DNA sequences that can be patented through genetic engineering practices. Seeds and crops can also be patented. That has caused issues for farmers who live near fields where genetically modified crops have been grown. The crops which have been genetically engineered have had their seeds spread to other fields, causing unintended growth where they land. Numerous property owners have been ordered to pay royalties and compensation for product loss because of this issue in Europe and North America because of the patenting process. Because of this liability threat, fewer farmers want to work their fields because it could cost them more than they might make.
