Biotechnology
GMO's
Pros
In some cases, crops don't have enough strength to adapt to resist against powerful viruses, such as the ring spot virus that plagued Hawaii in the late 20th century. Through the use of Genetic Modification, scientists were able to create a new generation of papaya that were immune to the virus, and the production of the fruit finally returned to normal.
GMO's can increase the shelf life of certain foods. This means that they could last longer and feed more people, including those who may not have a lot of access to healthy food.
Cons
GMO's used in crops increase the amount of herbicide usage, which most of the time have carcinogens in them. This poses a serious threat to the lives of farmers who don't wear any mask or equipment while using herbicides.
GMO's are relatively recent technology and their safety is currently unknown, meaning they could potentially have dangerous side-effects. This is the main reason why most people are against them, and don't want to risk their health for potentially better food.
Cloning :beer_mugs:
Pros
Cloning could potentially be used to replace organs. This could be very helpful when there aren't any donors, or if the organs are vital and can't be donated by a living person.
Cloning could potentially be very useful to genetic research. It could offer a lot of insight to scientist, such as the composition of genes and the effects of genetic constituents on human characteristics and traits.
Cons
If they started cloning humans, the cells of the human likely would be taken from an adult. This could cause the clone to age at a faster rate than a normal human, and clone's lifespan could be significantly shorter.
If cloning humans really does become a reality, all that scientists would need to clone you is one of your dead skin cells. If this is the case, people's privacy and security could be stolen by a cloned human, and many are worried about their rights that might be threatened by cloning humans.
Artificial Selection
Pros
Artificial Selection can be used to make plants and crops produce more during harvest. If they produce more food, more can be donated to those in need.
Artificial Selection could also provide crops with resistance to sever conditions. This would prove helpful during droughts and when large groups of pests and insects invade.
Cons
Crops might accidentally be susceptible to a certain disease, and could cause an entire species to be wiped out.
Could also cause deformations in new animals. This means they would have a smaller chance of long-term survival and a clear disadvantage in their ecosystem.
Bioremediation
Pros
Bio-remediation is very efficient in quickly cleaning up large amounts of pollution in both water and soil. This was demonstrated in London's Olympic Park, which was heavily polluted after years and years of industrial pollution and chemical runoff. After the use of bio-remediation in the soil, the area went from brown to green, and supported a large variety of wildlife, making the 2012 London Olympics the "greenest" in history.
Without bio-remediation, sewage treatment plants wouldn't be able to clean the large amounts of water that it does. This is because the main way they filter the water is with Microbes that eat away at all the waste.
Cons
Bio-remediation can be cheaper than other filtering systems, although it still has drawbacks. For one, the process can take longer than other alternatives and this could mean that not enough pollution is being filtered out of the sewage treatment plants in time for it to be cycled back through the community when they need it.
Even though the microbes are there to help the environment , they can actually end up hurting it also. They are still an invasive species, which means they always pose the threat of killing off the native species that are in the soil and water already.
