Genetic engineering - Don't Memorise

Here are the biggest key points to consider. 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. DNA insertion allows us to take this concept to new levels. 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. 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. Genetic engineering allows us to create food products that have a better nutritional profile.

That means we can get what we need nutritionally from fewer food products. In return, more food can be shipped to areas of the world where food insecurity is a major problem. Not only do we all get to eat healthier foods, but more people get to benefit from nutritionally dense foods when they are properly engineered. We can even use genetic engineering to extend the lifespan of foods, allowing them to be shipped further because they can survive longer and in harsher conditions.

Genetic engineering can also increase the rate of maturity that can be achieved for products within our food chain. This applies to plants and animals. We can see this practice working when looking at the history of broiler chickens. In the United States, the average slaughter age today is 47 days. In the European Union, the average slaughter age is 42 days. In , the average slaughter age was days. In , the average slaughter age was 85 days. At the same time, the average market weight has increased from just over 1 kg to 2. Genetic engineering does more than create healthier and faster products for our food chain. It can also create specific traits that make food products become more attractive.

Scientists can use DNA manipulation to create different food colors. A wider range of produce can be created by combining different items, like tomatoes and blueberries. Cows can be developed to produce more milk. Poultry can grow more muscle tissue at a faster rate. Even sheep can be manipulated to improve the quality of their coat for sheering. Genetic engineering can preserve crops as well. Bananas are constantly threatened by different types of disease.

Fungal diseases, Panama disease, and other influences have negatively affected banana crops over the last century. Most bananas at the grocery store come from one developed species, called Cavendish, because it was immune to the devastating diseases that affected other bananas. By engineering new types of bananas, additional disease resistance can be added to a species or crop and help it stay within the human food chain. Genetic engineering makes it possible for plants to grow outside of their normal growing seasons. They can also be modified to grow in harsher climates compared to plants without genetic engineering.

An example of this is plant gene At-DBF2. When this gene is inserted into a tomato plant, it increases the plants endurance in difficult climate conditions. It can even support growth in low-nutrient soil conditions. At the same time, the fruits or vegetables produced with this gene have a longer shelf life. This provides more profit potential while being able to feed more people. Genetic engineering could open a new field of medicine for humanity. We already have genetic testing in place to test for certain cancers.

We could use DNA manipulation to help treat or cure people who are born with genetic disorders. Even some cancers are considered hereditary and could be identified, even treated, through genetic engineering technologies. Over time, this could mean longer lifespans, a better quality of life, and faster disease treatment. Genetic engineering is already used in medicine to create a variety of treatments. We have vaccines, insulin, and even hormone treatments available because of genetic engineering.

As this science progresses, we can create more treatments that allow us to be proactive more often against pathogens that can have life-threatening characteristics. We currently have laws and treaties in place to prevent genetic engineering abuse. 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.

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. 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.

Although genetic engineering seems like it would increase diversity, it actually decreases it. That is because one preferred product becomes the focus of the industry when it performs well. This has been seen numerous times. There are hundreds of banana types, but only Cavendish bananas tend to be shipped to global markets. As a result, it takes hundreds of attempts to achieve just a few transgenic organisms.

So genetic engineering does not eliminate the need for traditional breeding. It is simply a way to add new traits to the pool. How does genetic engineering compare to traditional breeding? While genetic engineering manually moves genes from one organism to another, traditional breeding moves genes through mating, or crossing, the organisms in hopes of obtaining offspring with the desired combination of traits. Using the recipe analogy, traditional breeding is like taking two cookbooks and combining every other recipe from each into one cookbook. The product is a new cookbook with half of the recipes from each original book. Therefore, half of the genes in the offspring of a cross come from each parent. Traditional breeding is effective in improving traits, however, when compared with genetic engineering, it does have disadvantages.

Since breeding relies on the ability to mate two organisms to move genes, trait improvement is basically limited to those traits that already exist within that species. Genetic engineering, on the other hand, physically removes the genes from one organism and places them into the other. This eliminates the need for mating and allows the movement of genes between organisms of any species. Therefore, the potential traits that can be used are virtually unlimited.
