  • A Toxic Tour Through Picher

    A couple days ago I drove through Picher, Oklahoma as members of L.E.A.D. Agency gave a toxic tour. During this tour, we discussed the history of all the sites we had visited, their current states, and ways in which these sites are being remediated. There were quite a few sites that stood out to me during this tour.

    One of our first stops was by a large field of Tallgrass. I pulled off the side of the road into a small parking lot. I asked what we were stopping for. My first thought was that we were looking at the looming chat pile to our left. However, the actual focus was the field of grass, which once used to be a residential neighborhood. All of the homes had been destroyed. Much of the destruction can be attributed to the 2010 tornado which blew through Picher, tearing down homes and sandblasting the ones that remained standing with chat. One of the only remaining pieces of evidence that homes used to be there was the three space parking lot.

    Our next stop was by the Picher repository. From a distance, the repository looked like a gigantic, flat chat pile. However, it was actually made up of the chat and mining waste that could not be repurposed. The waste found here has extremely fine particle size and a darker color then most chat. When we stepped out of the truck, I noticed a trail of this waste running down the side of the hill. L.E.A.D. Agency informed me that this waste measures around 13,000 ppm of lead. This is far above the upper safe threshold of 400 ppm.

    The most shocking sight of the entire tour was the “Anti-Fountain of Youth”. After exiting the car a last time, I heard the noise of running water. At first, I thought it was the flowing noises from Tar Creek, but when I looked over the bridge, the water was relatively calm. After walking farther down the road, I saw the source of the noise. Slightly covered by the Tallgrass and cattail stems, there was an actual fountain spewing out orange-tinted water. This fountain was an old bore hole. The liquid being pumped out was acidic mine drainage (AMD), and it was flowing straight into Tar Creek. When I heard that the AMD was seeping out of the mines into the surrounding environment, I imagined a slow flow of water. The amount of pressure with which the AMD was being pumped out at, to the point at which it was going up in the air a couple feet was mind blowing.

    On a final note, I would like to say that we saw a beaver dam and a family of ducks in Tar Creek. This highlights how there is still life present in this creek, giving us even more reason why we must work our hardest to remediate it, and prevent events like this from occurring again in the future.

  • How can we Preserve Biodiversity?

    First, let’s answer the question: “What is biodiversity?”. Biodiversity is the term encompassing the variety of life, such as variety in species, in genes, and even ecosystems. This is a critical aspect of nature because it provides stability to an ecosystem, and greater resistance to disasters and disease.

    The main threats to biodiversity are habitat loss, invasive species, and overexploitation of resources. Humans play an important role in these three threats. For habitat loss, deforestation is a prime example of how humans cause biodiversity loss by destroying species’ habitats. Additionally, humans have been responsible for the introduction of many invasive species by means of transportation. Many of these invasive species were not intentionally introduced, but they would act as stowaways on ships or other vehicles, being transported to a foreign ecosystem where they could thrive and disrupt the balance and biodiversity. For the third threat, humans can over use the resources of the land by over fishing, hunting, or mining, which would destabilize biodiversity.

    So how can we prevent these issues from happening?

    As people living on this Earth, we should also care for it. While it would be unrealistic to address every single threat to biodiversity, we can at least reduce our own contributions to its decline. The best ways to do this are to reduce deforestation and set limits or taxes when fishing and hunting. There are many nations already implementing these changes, but for them to stick, the regulations must be even more strict than they are now. This strictness could come in forms of hard stops in terms of fishing and hunting activity after passing a specified amount, or increased taxes when it comes to deforestation.

    There are also many ways in which humans can address the invasive species problem. The first would be to minimize of completely get rid of human involvement in introducing invasive species to new ecosystem. This could be achieved by thoroughly checking vehicles for any stowaway species before departing. For the invasive species that have already been introduced to a new ecosystem, people can report them to local authorities. In some regions, the hunting of invasive species is allowed, and you may be rewarded for the amount of specimens you catch.

    While this blog has many proposed solutions to the broad threats to biodiversity, these solutions would be very difficult to achieve without substantial support and compliance from institutions. We must cooperate with each other and think about the good of this planet and its inhabitants (including us!) and build our world into a safer and healthier place for the future.

  • Where are Microplastics From? How can we Reduce Their Prevalence?

    Microplastics are found all over the world. In modern times, almost every single house will contain multiple sources of microplastics. Even the clothes you are wearing right now could be contributing microplastics to the environment. If you are wearing polyester, each time you move or brush something off your shirt, hundreds of microplastics would float off into the air. However, there are still plenty of clothes that are plastic-free; 100% organic fiber clothing, such as cotton, does not contribute any plastics.

    Clothing is one of the main sources of microplastics, with the other being tire wear. As you drive your car or ride a bike, the friction between the tires and the road will release microplastics into the air. While most believe bicycling is an environmentally-friendly activity, look into the tires you use because there is a chance they could be contributing to pollution. Transportation’s contribution to environmental damage is not just limited to energy sources and gas pollution. We must also look towards plastic pollution.

    But the question we should be asking is: “How can we reduce these microplastics?” The best way to start is inside your own home. Switching towels and clothing to 100% natural fibers will play a large role in eliminating your contribution of microplastics. When purchasing items from the grocery store, always be mindful of items with microbeads. While some countries have banned the usage of microplastics in rinse-off cosmetics as a direct effort to limit their introduction into water systems, they are still found in other items and countries.

    If you are interested in participating in a community-level activity, look for local environmental cleanups. These could be in creeks, on hikes, at local parks, or wherever else the environment needs help! By picking up plastic litter and abandoned pieces of clothings in these natural environments, you will be helping reduce microplastic pollution one step at a time.

  • The Role of Oceans in Climate Change

    Oceans play a crucial role in stabilizing Earth’s climate system, absorbing heat and carbon dioxide. They absorb about 30% of the carbon dioxide produced by human activities and generate half of the world’s oxygen. However, the escalating impacts of climate change are posing severe threats to the health of our oceans.

    One of the most pressing challenges is the rising temperature of ocean waters. This warming leads to coral bleaching and disrupts the delicate marine ecosystems upon which fisheries and global biodiversity heavily depend. Furthermore, as CO2 levels increase, the oceans become more acidic. This acidification negatively impacts marine species such as shellfish and corals, potentially altering entire marine food chains. Additionally, the combination of melting ice caps and the thermal expansion of seawater as it warms contributes to rising sea levels, which threaten coastal communities and habitats.

    Another significant issue is the deoxygenation of ocean waters. Warmer waters hold less oxygen, and disrupted oceanic circulation further depletes oxygen levels, affecting the survival of many marine species.

    To combat these challenges, several innovative solutions are being implemented. Marine Protected Areas (MPAs) are being designated to restrict human activities that damage the ecosystems and biodiversity of the oceans. Sustainable fishing practices are also crucial; they involve regulations that prevent overfishing, bycatch, and habitat destruction. Furthermore, the development of ocean-based renewable energy sources such as wave and tidal energy offers a promising avenue to reduce our dependence on fossil fuels. Additionally, projects aimed at enhancing the ocean’s natural ability to sequester carbon, such as algae farming and the deployment of artificial “ocean trees,” are being explored.

    Engaging the global community in these efforts is essential. Raising awareness about the vital role of oceans in the climate system and promoting international cooperation to implement effective policies can lead to substantial reductions in greenhouse gas emissions and greater protection of our marine environments.
