Using new technologies such as the hydrophone, scientists have discovered new ways to assess the health of coral reefs. Located on islands surrounding central Indonesia, scientists created a computer program that listens to the coral and reports back what sounds it hears. The AI collects information on the sound frequencies and volume. Healthy coral attracts animals and supports ecosystems with various creatures living on the reef, therefore complex and cackling-like sounds indicate a healthy coral. However, desolate and quiet sounds reveal that the coral is unhealthy. This information is used to help conservation efforts, as well as to track the progress of projects to rebuild coral. 

 

The AI system has a lot of potential in advancing efforts to rebuild and conserve coral reefs, which is important to focus on as day by day they get closer to extinction. With the damage from carbon gas emissions, oceans are warming quickly, and its acidity is rising as well. Coral reefs are being damaged from the ocean’s threatened health. However, with this new technology, scientists and environmental activists are able to easily locate where damaged coral reefs are, and begin working at a solution. I think with this new AI, coral reefs have more potential of staying healthy and helping to maintain the rest of the ocean and its ecosystems. 

Exploring the largest ocean reef restoration project in the Americas: ‘one million corals for Colombia’

On San Martin de Pajares Island, Marine Biologist Elvira Alvarado teaches youth volunteers how to plant fragments of coral as a part of the coral reef restoration project: “One Million Corals for Columbia”.  With the goal of planting one million fragments of coral, and restoring 200 hectares of reefs by 2023, this project has lots of pressure, and little time. Extinction of various species of coral is largely caused by disease, predation, climate change, sedimentation from pollution, etc. Through studies of coral reproduction and experimenting with different ways to repopulate coral species, Ms. Alvarado aims to restore the beauty of coral reefs. She has set up a bay coral nursery and uses a technique called Micro Fragmentation to grow and plant new corals throughout Columbia. 

 

This article is inspiring, as it shows how far a genuine passion can take you. Ms. Alvarado made her dream come true through endless effort and research. It reveals that with a goal and a desire for change, youth all over the world can produce changes and help our environment. With her project, more youth were able to understand the importance of what the ocean provides for all of society, and how we can support and help keep our oceans healthy. I think the technique they used to grow new corals should be used more often, as the results prove its efficiency. Since they used eco friendly and recycled materials to build the nurseries, this project can continue to thrive with future generations, supporting the Columbian ocean for decades. Revival of coral reefs brings more fish, leading to more food availability and resurgence human activities in that area. Corals also bring protection from natural floods and storms, as well as various medicines to help with human health. Overall, the revival of coral reefs benefits the ecosystem and humans. 

Woodside Community Halting all new building in effort to Protect Mountain Lions.

Jensen, T. (2022, February 4). Woodside Community Halting all new building in effort to Protect Mountain Lions. NBC Bay Area. Retrieved February 5, 2022, from https://www.nbcbayarea.com/news/local/peninsula/woodside-community-halting-all-new-building-in-effort-to-protect-mountain-lions/2800637/ 

The citizens in the city of Woodside, California have put their foot down when it comes to adding new buildings in their community in an effort to protect the community of mountain lions that inhabit the peninsula’s mountain regions from Redwood city to San Bruno. Community activists agree that the mountain lion presence in residential areas is increasing, and since they are an “threatened species and need the land to survive.” The city, with the support of Mayor Dick Brown, will vote to pass a town agreement as well as following the ideas of Senate Bill 9, which has been met with opposition by people who argue it is a move against having low income housing in the city.

I think that this is a good move for the city of Woodside, because it is a step in prioritizing endangered species over economy and profit. It is no secret that Bay Area real estate is highly profitable, especially in the Woodside, Hillsborough, and other mountain areas. So having an agreement as a town to protect the mountain lions and give them more area in nature as opposed to invading their habitat which makes them come into residential and urban areas which consequently deems them dangerous and could end in euthanization for them is very conscious of the community. While I see the opposition’s idea of how it could be preventative of having low income housing, it is my opinion that lower income housing can be implemented in other, already urban and developed areas of the Bay and not adding on and damaging what habitat is left. This relates to environmental science because it is related to litigation and town commitment to preserving habitats and taking action to protect an endangered species.

 

Orange County’s Environmental Racism Issue

Le, Lauren. (January 15, 2022). Orange County’s Environmental Racism Issue. Retrieved January 27, 2022, from Orange County’s Environmental Racism Issue | New University | UC Irvine

 

Despite efforts made by the state of California to mitigate the climate crisis, there are still many environmental hazards that are specifically affecting marginalized communities. In Orange County, it was recorded that lower income areas populated primarily by people of color had significantly higher pollution levels than other neighborhoods in the general area. In fact, areas housing people of color tended to have more issues like lead contamination or poor water and air quality. These pollutants can have devastating health effects, causing brain cancer among other things. Marginalized communities in the area also had higher concentrations of lead in their soil.

 

While California is making strides in terms of mitigating the ongoing climate crisis, it is not doing as good a job at mitigating the effects on marginalized communities. Communities made up of black, Hispanic, indigenous, and other minority groups have faced a long history of environmental injustice. Some efforts have been made to change this but overall, these communities have been disproportionately affected by climate change. This is a key example of the lack of environmental justice in America. This article was really concerning to me. Minority communities are being hit incredibly hard by pollution and other issues, and yet few are coming to their aid. Considering many of the communities are in low income areas, they need support, and it is up to those who are able (and the federal/state government) to help them. We can’t say that we are successfully mitigating the climate crisis until we reduce/eliminate the devastating effects of climate change on marginalized communities.

Colonialism, the climate crisis, and the need to center Indigenous voices

Climate adaptation is incredibly urgent across the US and the world, but it is especially important in Indigenous communities. Despite this, Indigenous people have often been left out of climate policy, even though they are some of the most affected by climate change. Indigenous people have long been active in climate activism, and yet they are most frequently excluded. Climate change itself is rooted in colonialism and the exploitation of native people and their land. Currently, some of the best ways to help indigenous people with climate justice are land stewardship, long-term financing, land reparations, and indigenous decision making. 

 

Indigenous communities are some of the most affected by climate change. Their land and rights have long been exploited and degraded, and yet even today indigenous voices are not being listened to. This is just one example of environmental inequality, and how Indigenous people are often ignored in favor of white settlers and colonists. This should not be happening; indigenous people tend to be very educated on the environment and take care to show their land respect. Most white colonists cannot say the same. After reading this article, I realized just how often indigenous voices have been shut out. They have crucial ideas on climate adaptation and mitigation, yet they are rarely listened to. I feel that we (non-indigenous people) need to do more to uplift indigenous voices, especially on climate related issues, and we also need to try to remedy the environmental injustice faced by most indigenous Americans.

Water protectors in Hawaii confront dangerous environmental polluter: the US military

Steiner, Mark. (January 20, 2022). Water protectors in Hawaii confront dangerous environmental polluter: the US military. Retrieved January 27, 2022, from Water protectors in Hawaii confront dangerous environmental polluter: the US military (therealnews.com)

 

The US Navy’s Red Hill Fuel Storage Facility has been leaking hundreds of thousands of gallons of petroleum into the aquifer that provides drinking water for thousands of Hawaii residents. This has been going on for years, even since the facility’s construction, and native Hawaiian residents have been speaking out about it to no avail. The facility didn’t pause operating until military families living in the area reported having symptoms of petroleum poisoning. Native Hawaiians have been fighting for their land and for their rights, but the US military is rarely held accountable for their operations in Oahu.

 

Upon reading this article, it is clear that native Hawaiians are being disproportionately affected by the issue of petroleum in their aquifers. Despite Hawai’ians speaking out their concerns for years, the US did nothing until families of their own members started complaining as well. This goes to show that the US military, and the US federal government in general, isn’t listening to native voices. I was really shocked after reading this article. I hadn’t heard anything about petroleum contaminating Oahu’s biggest aquifer before reading the article, despite it being a massive issue. It made me wonder why something so devastating hasn’t been more widely shared. The US military’s presence on the Hawaiian islands has caused a lot of lasting environmental damage, and yet it is rarely (if ever) spoken about. This is definitely a problem, and I feel that more should be done to hold the US military accountable for their actions against environmental justice for native Hawaiians.

Michigan community faces water crisis, calls for lead pipe replacement

Bohlke, Lily. (October 8, 2021). Michigan community faces water crisis, calls for lead pipe replacement. Retrieved January 27, 2022, from Michigan community faces water crisis, calls for lead pipe replacement | Detroit News | Detroit | Detroit Metro Times

 

Many drinking water systems across the US contain lead pipes. However, communities primarily made up of people of color are being disproportionately affected by this. Removing these lead pipes would be incredibly beneficial; since lead can affect children’s ability to read and write, removal of the pipes would benefit children’s education. Environmental agencies have been working to get safe drinking water for primarily black communities in southwestern Michigan, as the area has reported extremely high lead levels over the past few years. Many areas like this, with mainly people of color inhabitants, have been losing investments over the years, so it is crucial they get the support that they need.

 

This article is really closely tied to the topic of environmental justice, as it focuses on black communities (and other communities made up of people of color) being disproportionately affected by environmental crises. Lead contamination of drinking water is incredibly dangerous, and to make matters worse, some of these communities have been without safe water for years, and yet little has been done to fix this. I found the article to be really eye opening. I had heard of the “lead in water” issue in the past, such as what happened in Flint, Michigan, but I hadn’t realized that the crisis wasn’t one faced by all communities in the area. Upon learning about this, I’m upset to hear that our federal government hasn’t done much to fix this, despite multiple campaigns from environmental activists and the government’s general knowledge of the issue.

How much air pollution do you live with? It may depend on your skin color

McCormick, Erin. (December 15, 2021). How much air pollution do you live with? It may depend on your skin color. Retrieved January 27, 2022, from How much air pollution do you live with? It may depend on your skin color | Environment | The Guardian

 

The amount of pollution people are exposed to could be related to the color of one’s skin. When testing the levels of air pollution in various locations, it became clear that areas where people of color resided had more airborne pollutants. This disparity becomes even more apparent when one looks at urban areas; areas primarily made up of black and brown communities have significantly worse air quality and higher levels of pollutants in the air. While efforts have been made to improve air quality, there are still unequal levels of air pollution.

 

This article is related to environmental science and environmental justice because it focuses on air pollution; specifically how it disproportionately affects communities made up of people of color. Areas where a lot of people of color live have significantly worse air quality than areas where their white counterparts live do. I wasn’t entirely surprised hearing this since I had heard about this disparity before, but I was still upset to hear about it. Whether it’s purposeful or not, it is entirely unjust that frequently discriminated against communities have such poor air quality. That poor air quality can have lasting effects, causing health issues such as lung diseases. This article made me realize just how disproportionately people of color are being affected by the air quality; while many places have poor air quality, it is clear that black and brown communities are being forced to take the brunt of it.

Shell in Nigeria: Polluted communities ‘can sue in English courts’.

This article is about the recent ruling by the UK Supreme Court, which overturned a court of appeals ruling that says that people within a community in Nigeria can now sue Shell because of the oil pollution that they have caused in the area.  Shell, as a corporation, is responsible for 50% of the oil pollution in the waterways, which affects many families and fishermen who rely on this waterway for food and their livelihoods. This landmark ruling is significant, ShellAs because it shows that the UK is now taking the fight for Environmental Justice a little more seriously when it comes down to issues with corporations. Nigerians’ money made from this lawsuit could be enough to clean the pollution within their waterways. Despite this, many community members in this area have stated that the money will not bring back what they have lost, which is clean waterways, fish, and their community. This lawsuit is one of many that has recently been launched against Shell as a corporation that has been responsible for a lot of the oil spills and pollution in Nigeria as a country.

This article is really indicative of what’s going on in the world with environmental justice because it represents the intersection between companies who believe that they are right and who are disregarding the environment in these small communities. These communities are being put at a disadvantage because of things that are outside of their control and are not getting taken completely seriously. In this regard, this article makes me happy because companies are being held accountable for what they’ve done for so many years which I think is really important and there needs to be justice on that end. At the same time, it does seem apparent that there needs to be more done and there are a number of stories like this one and those also need to be solved.  This story is a step in the right direction for environmental justice, but it points to there being a lot of steps that still need to be taken. 

‘What’s at stake is the life of every being’: Saving the Brazilian Cerrado.

This article covers recent news about the Cerrado in Brazil: a biosphere home to many indigenous people and indigenous species of plants and animals. The area is currently in the news because Brazil’s new president (who is incredibly anti-pro-environmental policy) has hailed this area as an arid unfertile space that requires development. This designation invalidates the homes of the many people who live there, and the risk of development causes further strain on the environment.  52% of the Cerrado has been victim to deforestation in the past years for agricultural use. The Cerrado is currently the second-largest biosphere in Brazil outside of the Amazon. The improper designation that this environment needs to be altered or changed is incredibly false and pushes a harmful narrative. There have been many protests happening recently in the Cerrado led by indigenous people protecting their communities and improper land use.

 This article shows how much further the fight for environmental justice is within our world. In pieces like these, it becomes evident that most people are attempting to save for the environment is naive and not everyone has the environment’s best interests at heart.  This situation is also frustrating because the indigenous people who have lived in the Cerrado,  are people who truly care for the environment and are the people who are best at taking care of their environment. The idea that development is needed to save these environments or to use this land that might not be fertile is false. Not only has this environment been inaccurately labeled, but the government is also practically feeding lies to Brazilians to promote development that will not be sustainable and can cause a lot of harm to the environment. This issue is an essential environmental justice one because if citizens are unable to understand what is truly at stake they’re going to be less likely to care about issues of environmental justice themselves.
