Greenhouse gas emissions from Daihai Lake, China: Should eutrophication and salinity promote carbon emission dynamics?

PubMed. (2024, January 1). Greenhouse gas emissions from Daihai Lake, China: Should eutrophication and salinity promote carbon emission dynamics?

https://pubmed.ncbi.nlm.nih.gov/37778815/

 

This article provides a little bit more information regarding the correlation between algal blooms on greenhouse gasses. Lakes have always played an important role in absorbing and emitting greenhouse gasses, but it seems like eutrophication and nitrogen compound runoff is disturbing how lakes interact with methane and carbon dioxide. There still isn’t much known about eutrophic lakes and what it will mean for the future of climate change, but this study illuminates how there could be potentially dangerous effects from lake emissions.

 

This article is important because it gives context to the difficulties environmental scientists experience when doing research. Few studies have been done on this topic, and it prevents us from having a comprehensive look on interactions between greenhouse gasses and greenhouse gas sinks. Additionally, with how much lakes vary across the world, it makes it even more difficult to get a comprehensive understanding and then find a solution. But it still is incredibly important for us to understand, mostly because of how potent methane is as a greenhouse gas, and how if we have more than we expected then we need the flexibility to adapt to it. We need to tackle eutrophication, the main root cause of this, before it begins to exacerbate climate change as well.

Wetlands as a potential multi functioning tool to mitigate eutrophication and brownification

PubMed. (2024, January 29). Wetlands as a potential multi functioning tool to mitigate eutrophication and brownification.

https://pubmed.ncbi.nlm.nih.gov/38286682/

 

This article takes a look at the potential benefits of wetland restoration, and how it could mitigate the effects of eutrophication. The wetlands have the ability to capture and sequester nitrogen compounds, and microbes living in the soil can change those compounds into less damaging forms. However, there is a difference between generalist and specialist wetlands, and their efficiency in reducing nitrogen compounds, so much more research is required so we can effectively utilize restored wetlands.

 

This article is important for environmental science, because it shines a bit of hope on a situation that is looking a little grim. If wetland restoration truly has the potential to mitigate eutrophication, then it is incredibly good news because it means that we can help solve several problems at once. Wetland restoration is great for helping mitigate rising oceans, and provides valuable ecosystems for many different species. If restoring wetlands means that we can also reduce the effects of eutrophication, then that puts less stress on both aquatic ecosystems and environmental scientists as more permanent solutions are found.

Mariculture may intensify eutrophication but could lower Nitrogen/Phosphorus ratios.

Mariculture is a form of marine farming, or cultivating marine organisms in enclosed spaces for food or other animal products. Mariculture plays an important role in meeting growing food demands, as well as being effective in aiding carbon sequestration. However, it threatens local ecosystems by throwing nutrient levels out of balance, causing eutrophication. This article examines how different types of mariculture have different impacts in the Sansha Bay in southeastern China, which raises both shellfish and grows seaweed. One method, called fed culture, (cages and ponds) utilizes nitrogen compounds to feed cultured organisms. The study shows that there is quite a bit of nitrogen and phosphorus compounds that are not utilized in the process of cultivation, which does lead to higher rates of coastal eutrophication. However, there is a second, more environmentally-friendly version of mariculture. This method involves seaweed cultivation, which acts as a nutrient sink and can offset the effects of fed culture and eutrophication.

 

The article is related to environmental science because it shows the dangers of mariculture and how our consumption can lead to more problems down the line. The increase in demand for seafood has led to an increase in mariculture, and that has led to dangerous algal blooms further down the line. However, there is a silver-lining. We can move towards other things to cultivate, such as seaweed. This will help combat the nutrient runoff, and seaweed is also a great source of food and can be turned into biofuels. Additionally, increased amounts of seaweed will help aid the ocean in removing excess CO2, helping with carbon neutrality. This is significant because if we adopt more sustainable mariculture models, then better ocean health will be promoted. Ocean acidification (which does affect mariculture of shellfish) will slow down, less coastal areas will become dead zones from eutrophication, and we could still meet growing food demands.

Researchers Warn on Eutrophication Potential of Ammonia

MarineLink. (2024, February 5). Researchers Warn on Eutrophication Potential of Ammonia.

https://www.marinelink.com/news/researchers-warn-eutrophication-potential-511321

 

A push towards alternative fuels could potentially create even larger environmental impacts, in the form of eutrophication. Ammonia has its advantages as an alternative fuel, namely its low cost and being a mostly clean fuel. Unfortunately, it seems to be limited by it not being green enough. Studies show that it is related to releasing nitrogen compounds, which is very dangerous for sensitive ecosystems that are already being threatened by eutrophication.

 

This article highlights an important problem in environmental science. We are looking for alternatives, but it is hard finding solutions to our problems that don’t immediately create new ones. In this case, finding alternative solutions to fossil fuels is very important, but creates algal blooms that end up releasing CO2 anyways as well as destroying the oceans effectiveness as a carbon sink.

Pollution/eutrophication risks worsening global water scarcity

Phys.org (2024, February 6). Pollution risks worsening global water scarcity: Study.

https://phys.org/news/2024-02-pollution-worsening-global-scarcity.html

This article is about how eutrophication can affect water scarcity. A recent study shows how 3 billion more people than expected could be at risk of facing water scarcity by 2050, and the cause is increased pollution rendering river sources unsafe for people and wildlife alike. Combined with chemical and plastic pollution, eutrophication can compromise water quality. As seen in previous articles, the algae blooms can choke ecosystems and release dangerous products (such as neurotoxins) into our limited water sources.

 

This article is related to Environmental Science because it shows a more global scale of cascading effects from nitrogen fertilizers and eutrophication. When I did the original California one, I focused on the effects of cyanobacteria and algal blooms in the Bay Area. This article confirms that the same things we see here will potentially threaten much of the world if things do not change. The article mentioned how around half the world’s population is at risk of water scarcity, without factoring in the effects of eutrophication. If this study is right, then more people would not have access to clean and safe water than those who do, in only about 25 years. This article puts heavy emphasis on how soon that is, and the scale of the massive problem that we face.

Town of Oyster Bay. (2023, August 14). Free Oyster Harbor Cleanup & Marine Education expo. Town of Oyster Bay. https://oysterbaytown.com/free-oyster-harbor-cleanup-marine-education-expo/ 

 

The Free Oyster Harbor Cleanup & Marine Education Expo event offers both a cleanup opportunity and educational experience. People can participate in the cleanup of Oyster harbor while also participating in marine-focused educational activities. This event is to promote environmental awareness and restoration, combining hands-on cleanup efforts with informative sessions to foster a deeper understanding of marine ecosystems and their preservation.

 

This is an example of a town promoting their beach clean-up day because even the smaller efforts can make a difference. Once people are out there restoring the ecosystems, they are given a chance to learn more about marine wildlife and hopefully inspire them to care about the wildlife in their area.

Battle Begins to Ban Natural Gas in New Chicago Homes, Businesses to Fight Climate Change – AC

This article discusses the issues regarding climate change in the harsh winter of Chicago. Elected officials in Chicago are examining how to enable Chicago winds to heat their homes in the winter months while making this heated air safe to breathe. The article talked about the state of Illinois’s desire to transition to clean energy by 2050. However, Chicago has extreme financial issues surrounding poverty so relying on electricity would not provide affordable heating for Chicagoans. However, the article discussed how Chicagoans could financially benefit from transitioning to electric powered stoves as opposed to gas appliances. It is evident that the article understands that climate change is making Chicago’s winters more and more dangerous and we cannot put people’s health in jeopardy to simply stay warm.

I thought this article was pretty shocking, actually because it almost feels that Chicago is in a helpless state given climate change. It seems nearly financially impossible to transition to all electric power, but people need to notice how the fixed cost of electric stoves and heating appliances may be more than gas, however the variable cost for electric power is extremely beneficial. Furthermore, I believe that Chicago should rely a little bit more on nuclear power while climate change creates even colder winter temperatures that commonly dip below zero. I think it may not be a horrible idea to impose a tax on gas appliances so we can promote healthy warming strategies in the face of a climate change disaster throughout the midwest.

Meat Production In California

Kodas, Michael. “California’s Top Methane Emitter Is a Vast Cattle Feedlot. for Now, Federal and State Greenhouse Gas Regulators Are Giving It a Pass.” Inside Climate News, 25 Aug. 2023, insideclimatenews.org/news/18082023/californias-top-methane-emitter-is-cattle-feedlot/. 

This article describes the effect that burning methane has on the environment and how different agencies and groups are trying to stop and protect the environment. It also describes the different effects of biofuels that are related to the cattle and how things like their decomposition affects the different levels of GHG in the atmosphere. it describes how a lot of people don’t recognize the impact that the food source of cattle and the whole thing with meat production has a huge amount of methane production that is severe for the environment and how the government covers it up due to the necessity for the food source and rights it off as needed transportation and undermines the affects.

 

I think that meat production in general is something very controversial due to the fact that we consume large amounts of it but the fact is that the meat prosecution industry produces large amounts of carbon dioxide and methane that is not something that can be easily gotten rid of. It’s not just the cattle necessary as the dairy industry and the use of the cattles waste also have their consequences, and this is very big dilemma as we need to food as were are to rooted into the meat industry to just let it go but we also have the problem of rising climate change and the difficulty we have faced with trying to combat it .
