While plastics have been in use for many decades, plastic pollution has become a pressing contemporary issue. Half of all plastics ever manufactured were produced in the last 15 years. This pollution is one of the most urgent environmental problems we face today, contributing to the acceleration of global warming and resulting in more severe and frequent floods, forest fires, and other disasters. Furthermore, plastic pollution has a direct and negative impact on both marine and terrestrial ecosystems.

Plastic is everywhere and lots of it ends up in the ocean. Most plastics in the ocean break up into very small particles (5mm or under) called "microplastics." Other plastics that are intentionally designed to be small are called microbeads and are used in many health and beauty products. They pass unchanged through waterways into the ocean. Aquatic life can mistake microplastics for food. In 2015, the U.S. banned the use of microbeads but microplastics are still a huge problem! You can help keep plastic out of the ocean. Remember: Reduce. Reuse. Recycle.”Â

Marine life: Microplastics can be toxic to marine life, causing oxidative damage, abnormal behavior, and delayed growth. They can also reduce food intake and affect fish's ability to survive and reproduce.Â
Food chain: Microplastics can act as carriers of other pollutants in the food chain. They can also be ingested by smaller organisms, which are then eaten by larger predators, eventually ending up in seafood.Â
Plankton communities: Microplastics can alter plankton communities, exacerbating deoxygenation and starving marine organisms of oxygen.Â
Marine sediments: Microplastics can disrupt nitrogen cycling and alter microbial communities.Â
Beach sand: Microplastics can blend with beach sand and appear as grains of sand or tiny pebbles.Â
Marine snow: Microplastics can be funneled to the deep along with marine snow, eventually settling on the seafloor.Â
What’s the problem with microplastics and microfibers? Well, microplastics are extremely easy to form, and they wander everywhere. From water to the air we breathe, microplastics are unavoidable. These pesky things are in our bodies, and scientists have made discoveries that these plastics increase the risk of heart disease. And this is alarming, since plastic is very useful in our time. It wouldn’t make any sense if these plastics have not had impacts on society. The solution would be to remove the microplastics in our oceans to save the environment and improve our drinking water. By improving our water we can avoid health issues such as heart disease.
We should keep the oceans clean because the oceans provide food and is full of fish and marine life. Also it provides most of the water we drink.

An estuary is where freshwater rivers meet the salty open sea. Estuaries are home to unique plant and animal communities adapted to brackish water. Estuaries are among the most productive ecosystems in the world. Many animals, especially ocean animals, rely on estuaries for food, breeding places, and migration stopovers.
The Hudson Estuary is important because it provides a diverse and vital ecosystem for a wide range of aquatic life. It serves as a critical nursery ground for commercially and recreationally important fish species like striped bass and bluefish. While also offering a unique habitat transition zone between freshwater and saltwater, it is ecologically and economically valuable to the Atlantic Coast region.

 Session with Invited Expert
The BotCats had a meeting with a special guest who does research and observations on the estuary, Noelle. Â Discussion began with The Clean Water Act of 1972, how it helped & more work to be done (globally and locally.) She offered to help the team with research (references and field research.)
Notes From Our DiscussionÂ
PROBLEMS WITH PLASTICS IN THE WATER
Plastics are not eco-friendly
Plastics get smaller and then are eaten by fish. Â
Plastics are found in organisms living in the estuary.
Plastics often kill organisms/ affect health/ reproduction
Chemicals & pollutants (eg.) oil (from an oil spill) sticking to plastics get ingested by organisms along with the plastic
WHY ARE THERE PLASTICS IN THE WATER?
People throw them directly into the water.
Items can be blown into the water.
Landfills (Rain & floods wash plastics into rivers, estuaries, then flow into the ocean.)Â
Plastic items close to the water often runoff into the water (eg.) soccer field pellets
Items containing plastics (eg.) tea bags composted in home yards
Nicole discussed her MA degree research project (Study of trash, recycling containers, & how utilized near the Hoboken waterfront.
Session with Invited Expert
The BobCats met with special guest, Justin, Manager of Research and Aquaria at Hudson River Park Trust.  Discussion began with general research done by Hudson River Park Trust of the Hudson River (ecology & animals). HRPT did a microplastics study (2015-2019), published 2020. Since then, the organization has pivoted toward partnering with other schools/organizations who have the tools/expertise to conduct microplastic research.Â
Notes From Our DiscussionÂ
Problems with Plastics in the Water
Microplastics travel through the food chain and are eaten by microscopic plankton.
Chemicals and bacteria stick to plastic.
Microplastics can be vectors for microscopic pathogens.
Critical Ways Microplastics Affect Marine Life
Ingestion of plastics causes poor nutrition and possible starvation.
Animals can choke on microplastics.
Ingestion over time leads to bioaccumulation of microplastics as you go up the food chain.
Animals most affected are big predators
Filter feeding organisms (oysters, bivalve mussels) greatly affected by microplastics.
Justin discussed doing a trawling survey and analyzing samples of microplastics using a Raman Spectrometer at a partnering university as part of Hudson River Park Trust 2020 Microplastic study.
Some team members deployed eel mops using different fibers, coconut, jute, and polypropylene attached to a ceramic tile and two oyster cages in the Hudson Estuary. They studied them for nine months, from February to October 2024. We registered the specimens we found and observed the conditions of the materials used for the mops and the impacts that these materials may have on the specimens. We registered water quality, weather, and river conditions during the experiment. Our eel mops and oyster cages supported life. Although eco-friendly eel mops have shorter life spans, the coconut mop proved suitable for monitoring glass eels while being a safe environment for species without polluting the estuary. In our two last data collections, we finally found Eastern oysters and ribbed mussels that naturally grow in the oyster cages.

Beach cleanups are essential for many reasons, including:
Protecting marine life: Debris in the ocean can harm or kill marine creatures by getting caught in it or being ingested.Â
Preventing pollution: Litter on the beach can quickly end up in the ocean, contaminating the water and harming marine life and humans.Â
Maintaining coastal ecosystems: Removing trash helps maintain the balance of coastal ecosystems, which are vital to the survival of many species.Â
Promoting environmental awareness: Beach cleanups can help raise awareness of marine litter issues.Â
Getting exercise: Beach cleanups can be a fun way to get some exercise.Â
Learning: Beach cleanups can be a great way for kids to learn about marine debris issues and how to help protect the aquatic environment.Â
Even though the beach appeared clean, we found an alarming amount of microplastics and litter, primarily foam, food containers, plastic wrappers, and bottle caps.Â
Our Community Event initiative gained support from several local community organizations, including the Hoboken Fund for a Better Waterfront, Hoboken Family Alliance, and Hoboken Mommies, who have promoted it on their social media platforms.Â
Halloween Art Installation: We capitalized on Halloween's popularity in Hoboken to create a campaign with a striking and scary factual message.
Email companies to invite them to join the efforts to eliminate microplastics. During our "Hoboken Plastic Free" cleanup, we found several branded, one-used plastic products. We emailed those companies to tell them what happened, ask them to help us educate their consumers, and remind them to discard the garbage in the correct receptacle. We also asked companies to consider changing to biodegradable, eco-friendly materials.
We participated in the NY-NJ HEP Photo Contest, "Working Together for a Thriving Harbor and Estuary." This year's conference highlighted the activities, partnerships, and research that will contribute to NY-NJ HEP's draft 2025-2035 Action Agenda and help them address the estuary's challenges. The event involved the participation of college professors and college graduates or undergraduates. The BotCats were accepted to participate and won the photo contest. We became the image for the HEP 2024 conference and the Action Agenda 2025-2035.
With this clean-up, we participated in The International Coastal Cleanup, the world’s largest volunteer effort on behalf of the ocean and waterway health. This is an initiative by the Ocean Conservancy Organization. We used their forms and following their requirements.
We created alternatives to plastics to reduce the environmental and economic impacts of plastic waste:Â
Reduce plastic pollution: Biomaterials can be biodegradable and compostable, reducing the amount of plastic in landfills and oceans.Â
Lower carbon footprint: Biomaterials can be made from renewable resources and require less energy than traditional plastics.Â
Create new markets: Biomaterials can create new markets for agricultural products.Â
Improve food safety: Biomaterials can be used for food packaging.Â
Reduce dependence on fossil fuels: Biomaterials can reduce the need for non-renewable resources.Â
"I love this recipe because it is just so versatile! It can be used to cast large sheets of thick material for sewing and or to form fabric bio-composites. It can be poured over existing structures once viscous or used as cushioning. Personally I find this material to be a good substitute for packaging and furniture foam."
Ingredients.
Metric: 100 mL water, 30 mL glycerin (pure), 30 g gelatin, 10 g beeswax, 2.5 mL dish soap.
Imperial: 0.5 cups water, 2 tbsp glycerin (pure), 10 tsp gelatin, 2 tsp beeswax, 1/2 tsp dish soap.
Equipment: nonstick pot, whisk or blender.
Preparation
Combine the water, gelatin, and glycerin in a nonstick pot.
Heat over low until mixture just begins to simmer.
Heat the beeswax in a microwave for 30 seconds or until liquid. Add beeswax to the mixture and stir until homogenous.
Add in the dish soap and turn off the heat.
Allow the mixture to cool to the point where it is no longer steaming and begin to whisk.
Pour into mold.
After the material is mixed overheat, it needs to be whisked to incorporate air into the matrix which will give it its foam-like texture. If you've ever made marshmallows from scratch, this texture should be very familiar to you! I find the best time to begin whisking is as the mixture begins to cool; it will start to noticeably rise in the bowl as the air bubbles you whip into it are held in the sticky matrix. If you overmix it however you can knock the air bubbles right back out again. At this stage the Biofoam can be poured into a mold, or even poured over existing structures if you like.Â
It should be quite viscous.

This year, during the off-season, the team created a BotCats Code of Conduct, which became an essential tool when we welcomed new members.
The team members explore how to present themselves and their experience in the Lego league by drawing, and members come together to deliver our Lego SUBMERGED season logo.
To the left is the team Logo made by team members in 2022.
To the right is the MASTERPIECE BotCats Logo made by team member Arthur Kennedy during the state tournament in 2023.
We organized an activity at our school for the 3rd-grade students to learn about the FLL program and this year's BotCats project, which focuses on microplastics in the ocean. At the end of the session, the children participated in a fun quiz game we created using Kahoot: "How much do you know about microplastics in the ocean?" It was an excellent way for them to have fun while learning a lot.
With the generous support of our sponsor, the BotCats donate a Lego Spike Prime kit or expandable set to the HCS robotics club every year. We aim to provide the younger grades with all the tools they need to practice and develop a passion for coding, just as we have.
