Genetically Modified Corn Disadvantages

Improved Essays
Genetically Modified Corn
Genetically modified corn has many disadvantages and advantages. One advantage is that corn is being genetically modified to be herbicide resistant and to produce its own pesticide. Another advantage is that crop yields are being increased through genetic modification. The disadvantages are environmental issues such as, the decrease of insect populations due to the growth of corn that produces its own pesticide. Also, Genetic Modification is a growing field and the health concerns associated with eating genetically modified foods are unknown. Another disadvantage is that corn is often grown using monoculture. This means that all individuals are clones of each other, so all of them are susceptible to the same diseases.

Fish eggs are more sensitive to pH changes than fish adults, and thus the population numbers may dwindle if this impact is significant.
Ocean Acidification has also been shown to reduce the ability of fish larvae to find suitable habitat and find their way home.
Lots of species of fish live in and around coral reefs, and most feed on the microbes in the water, which provide fish with their carbon requirements. In general, the overarching effects of ocean acidification on coral formation and the abundance of carbon in the food chain will impact fish species through habitat and food availability.
Sea level rise
The projections for sea level rise in and around the Great Barrier Reef suggest much of the coast line will be inundated with water, resulting in major changes to mangrove and seagrass beds in these areas. These habitats provide protection and food resources for juvenile fish.
There are also species of fish on the Great Barrier Reef that live in both freshwater and saltwater habitats and changes to the pathways between these two habitats will make moving between them difficult for those species, including

    The world is being overtaken by corn, which is not a huge surprise if one looks on that back of almost all grocery items. But this creates a problem that is known as monoculture, which means the world is becoming too dependant on corn. There are risks that come with monoculture, such as bug infestation and plant disease. Companies avoid these problems by spraying crops with large amounts of pesticides and similar chemicals. The chemicals can enter runoff and eventually end up in bodies of water ranging from oceans to our drinking supply.…

    The acidification of our oceans increases the likelihood of coral reefs to be destroyed or broken down due to erosion. These nearly extinct ecosystems that are either becoming unstable or are being destroyed forces species to find another environment to make their home or to adapt in. The low survival rate of coral reefs under such harsh conditions makes the survival rate of other organisms detrimental as well because it leaves them vulnerable with the reduced amount of living spaces for fish. Leaving fish open to predators, it also has a harmful effects on a fish’s organs. Even though fish do not have shells, they are still affected by the changes that ocean acidification can cause.…

    A study found that the squid are vulnerable to the acidic conditions, and may face greater challenges to survival if this condition continues to amplify (Lacoue-Labarthe). The question is that how ocean acidification affects on the squid population. However, the answer might not be easy since there is a limited number of studies that have investigated squid response to the level of pH in ocean. There are many studies have shown that the most effect species are calcifying organisms at the bottom of the food chain are prey for marine organisms in higher trophic levels. Reducing the pH level in ocean also decrease the availability of dissolved carbonate ion necessary for shell formation.…

    Thousands of species live on coral, and if more corals are dying, these species will suffer as well (Fujita). Krill populations have dropped by 80% because they like to breed in colder waters (“What is Happening in the Ocean?”). They are an important link at the base of the food chain, and they reproduce in notably smaller numbers when temperatures rise. This disrupts the life cycle of organisms that eat krill, which causes food shortages for higher predators (“Sea Temperature Rise”). Algae are also affected by warmer ocean temperatures because they cannot complete photosynthesis if the water is too warm.…

    When coral reefs disappear it will cause a chain reaction affecting people all over the world. "We are seeing an overall negative impact from ocean acidification directly on organisms and on some key ecosystems that help provide food for billions. We need to start thinking about the risk to food security" (CNN World). People don’t understand the severity of what we are doing to the ocean and the world. If no action is taken and we continue on with our daily lives not caring about the long term effects of our actions then it could wipe out entire ecosystems or entire populations of sea…

    Another reason why I thought corn should be considered safe was because it’s protected from any deadly insects that are harmful to the environment.

    (“Playing Ecological Roulette with Mother Nature’s Designs”). One major risk that genetic engineered plants can cause is not having the ability to become weeds or pests themselves and the crops that are genetically engineered can lack vitamins, proteins, and other necessary things that are needed for human being who consumes the product and it can also affect the human body as well because genetic material can enter the human body through food, bacteria, viruses, vaccines, medications. (“Redesigning the World – Ethical Questions About Genetic Engineering”). Another risks is that if animals are constantly modified there is a risk of biodiversity thus leading to the worst thing of all the extinction of the certain animal. Besides extinction it could also cause a disruption in the environment since it was created on that certain “balance” that keeps everything in place.…

    Acid Rain is best described as any form of precipitation with high levels of nitric and sulfuric acid. Acid rain or acid deposition is the result of burning of fossil fuels. About two-thirds of SO2 and one-fourth of NOx are released into the air; it comes from electric power generators. These chemicals react would react with water, oxygen, and other substances to form delicate solution of sulfuric and nitric acid to form acidic pollutants. The source of sulphur dioxide comes from volcanoes, biological decay, forest fires; nitrogen oxides also comes from volcanoes and biological decay.…

    A few examples of these organisms include phytoplankton, coral as well as sponges. Acidification would cause a domino effect, for example, if the organisms such as phytoplankton and coral that depended on calcium carbonate would die, then the other species that depended on those organisms for a food source would also die. (eaq.org) Conversely, acidification is not the only harmful aftermath of humans. Acidification can cause the ocean to absorb greenhouse gases, which warms the ocean, and this is disturbing because it can generate formidable storms such as hurricanes.…

    Advantages: • GM crops are resistant to pests which mean that a gene is transferred to the plant which makes it resistant to pests and kills the pests instead. This will result in the growth of a larger crop, increased yield and also a financial gain as less pesticide is being used. May improve farmer or farm workers health. • GM crops can be seen as a benefit to underdeveloped countries as it is providing more crops for less money. • GM foods are more nutritious as more nutritional substances can be introduced into the transgenic variety meaning that more nutritional genes can be transferred into the crops or food.…
