Pros And Cons Of Geoengineering

Good Essays
As climate change becomes an increasingly pressing issue, humanity is finding new ways to combat this problem. Geoengineering is growing in popularity as a solution to slowing and preventing future global warming. By manipulating the existing processes in the environment, geoengineering. In the case of iron fertilisation, large quantities of iron are deposited in oceans in order to stimulate a bloom in phytoplankton populations; for photosynthesis to occur, iron is needed. An increase in phytoplankton populations would greatly aid the marine food chain and be successful in removing carbon dioxide from the atmosphere.
However, there is much debate whether geoengineering should be implemented. Although there is evidence to support its benefits, none of this evidence was taken from a large-scale experiment. There are many different factors that influence the controversy surrounding geoengineering. Nonetheless, due to the proven benefits of iron fertilisation, it is being seriously considered by many experts in the field. Iron fertilisation has been shown to boost

This argument is used to oppose the assertion that they have been greatly reduced over the last century. These studies, taking place around 2000, found up to a four percent increase in phytoplankton, especially in coastal areas (Siegel).
Another argument that is frequently made when discussing iron fertilisation is that of interference and potential complete disruption of ecosystems. This could easily violate the existing environmental laws surrounding the subject of iron fertilisation in general (Parthasarathy). By fertilizing iron-deficient areas of oceans, humans would voluntarily change an ecosystem. This sudden change could favour certain species and therefore cause a species imbalance that is the cause of extinction of several

    However, because of the cost and the reduction rate is very little when looked at other factors. The second article offers us another solution by artificially enhancing the growth of phytoplankton, which play a role in carbon dioxide just as land plants do. Researchers and government officials would have to adding nutrients, such as iron, to the oceans for this to be accomplished. However, critics argue that while this may seem greatly beneficial, the lack of knowledge about the consequences it can have worries them. They don’t want the oceans stability to change and can potentially lead to a disturbance in the world’s homeostasis.…

    Although we are unsure if acidification can lead to coral bleaching at this time, it is obvious to see the negative effects it is having on our reefs (Ware). The Ocean Portal Team at the Smithsonian dig deeper into the acidification process and allow for a better understanding of the progression. The article describes the activity of acidification as the abundance of carbon emissions expelled by humans and the ocean’s organisms’ inability to break it all down. With our heavy reliance on greenhouse gases, we have now pumped more carbon into the atmosphere than it can naturally handle. As a result, ocean organisms are intaking a lot of this carbon, which has led to a reduction in pH of the waters.…

    The increase of food crops can lead to deforestation, alteration of the biodiversity, inappropriate use of land, contamination of the water supplies and the excessive use of fertilizer and pesticides. I also think that USA as one of the major leaders in the world should be the one to produce biofuels and with this the idea for other countries to join in the future. There are different reasons for biofuels to be important in many nations but the major one is to save our planet for future generations. The environmental reasons and the emission of green-house gases are at the top of the list as the more relevant. Just as in the discussion, I found myself in the position to start on the pro side of the subject, but the more I read the more I moved to be neutral for the many big issues and barriers that appear in…

    Andrea A. Lunsford claims, “the opportune moment; in arguments, the timeliness of an argument and the most opportune ways to make it”(E.A.A). Kairos helps me appeal to environmentalists about how the environment is currently being affected by global warming. Having temperature rise due to global warming is affecting the ecosystems. The author of “Climate Change” points out, “rising temperatures are depressing some plants and animals populations, driving species toward the poles , shifting migrations and behavior”. This article is important because it allows me to talk about the problems that global warming is causing towards the marine ecosystem.…

    In order to maintain a healthy green planet; firstly, “planting more trees will absorb more carbon from the atmosphere” (Mackey 19). Secondly, the idea of geoengineering could be implied to stave off the issue of global warming. The global climate change is an incalculable issue today. You would rarely find a person not au fait with this issue. Melting glaciers, ocean acidification, rising sea levels, and increasing concentration of carbon dioxide in the atmosphere are all consequences of global warming.…

    The lives of not only humans are at stake when experimenting with the planet, every living organism and ecosystem will have to deal with the possible irreversible consequences of these experiments. One of the biggest fears about the idea of geo-engineering is the fear that by talking about this technology or researching it and popularizing it will lessen the strength of the companies’ commitment to cut carbon emissions (Izrael). There are many other options instead of this technology; many scientists are working hard to provide the planet with a reasonable cure. A promising one is to engineer cyanobacteria for the consumption of CO2 and in the process produce useful organic acids and fuels. This type of technology would not interfere with ecosystems and natural…

    The rise in sea level will also pollute the fresh ground water supply with salty water. According to the article “Global Warming Fast Facts,” the National Geographic News published news in June 2007 claiming that, “Coral reefs are highly sensitive to small changes in water temperature and they suffered the worst depletion ever recorded. Some areas seeing bleach rates of even 70 percent. Experts expect these sorts of events to increase in frequency and intensity in the next 50 years as the sea temperatures rise.” Reservoirs and water sources may dry up if temperatures increase drastically, particularly if rainfall also decreases. Global warming also has a striking effect on human health.…

    After exposing the crawfish to water tanks, then increasing the temperature, aggressiveness and activity increased tenfold with a minimal amount of temperature change (Dapeng & Peishan 968). Eventually, invasive aquatic species will overtake the environment and native species will become scarce, and possibly die out, which is just another piece of evidence relaying the connection between climate change and the extinction of animal species. Global warming impacts all aquatic ecosystems, such as plants, fish, and coral reefs (Beckrich…
