Helping Our Watershed One Bioreactor at a Time

2023, LOVELAND, COLORADO, USA

Ella Corrigan and Reagan McWhinney from Resurrection Christian School addressed the use of toxic chemical fertilizers by creating 7 compost systems, specifically John-Su Bioreactors. Improper use of chemical fertilizers adds high amounts of nitrogen and phosphorus into the environment causing eutrophication. Food waste also generates methane gas, contributing to climate change. With the help of the Johnson-Su bioreactors, microorganisms and nutrients can be added to the soil without the use of harmful chemicals. Furthermore, local food waste will be limited by this new composting opportunity. Throughout this semester, Ella and Reagan built and filled the bioreactors which are now on the RCS farm. In merely 9-12 months, the nutrients will be ready for farming and gardening use. This solution addressed Targets 12.5 and 15.4 of the Sustainable Development Goals.

Follow the Litter

2023, FORT COLLINS, COLORADO, USA

Isabella Caterisano and Nera Wilson, students from Rocky Mountain High School, took a stand against plastic waste by providing reusable bottles to individuals in need. Motivated by the sight of plastic waste scattered across their local watershed, they decided to take action. Isabella and Nera collaborated to distribute 160 water bottles to Fort Collins Cafe, aiming to reach community members who require assistance. They specifically chose this location due to its accessible water bottle filling station, which serves both the general public and the homeless population. To raise awareness about the problem they were addressing, these dedicated individuals designed and affixed an educational sticker on each water bottle. This solution addressed Targets 6.6 and 6.1 of the Sustainable Development Goals.

Bat Boxes

2023, GREELEY, COLORADO, USA

The Intense Functional Learning class from Greeley Central High School addressed the decreasing population of endangered bats by building bat boxes. There are several species of endangered bats that are native to Colorado. With fewer trees in the cities and along trails, it is increasingly dangerous for them to live. The class built bat boxes to give bats a safe place to live. This will help bats survive and repopulate the area. Placing bat boxes along the Poudre River Trail gives bats a place to stay safe and warm near water so they can survive through any condition. The boxes will be monitored for use and if any endangered species take up residence within them. This solution addressed Targets 15.1 and 15.5 of the Sustainable Development Goals.

Why We Need Green Cleaning

2023, BERTHOUD, COLORADO, USA

Olivia Martinez from Berthoud High School addressed the effects of the improper use of chemical cleaning products on her watershed by creating green cleaning kits containing ingredients that are not harmful to the watershed. Olivia’s project helped find better products for families, industrial buildings, and schools that will essentially benefit the watershed rather than hurt it. Changing the way we clean would ultimately help the environment by reducing air pollution, protecting endangered species, and can assist in preserving Earth’s natural resources. This solution addressed Targets 14.1 and 6.1 of the Sustainable Development Goals.

Rocky Mountain High School, Fort Collins, Colorado, USA

The monarch butterfly population is decreasing fast which is why Jake Anselmo from Rocky Mountain High School decided to take action. Monarch butterflies migrate across the continent providing an invaluable service as pollinators. Their role as pollinators is essential for many ecosystems to thrive. In an effort to address his concern, Jake planted native milkweed in his watershed. Monarch butterflies depend on milkweed for laying their eggs and for nourishment. Milkweed, unfortunately, has also decreased in Jake’s watershed due to the loss of habitat from land development and the improper spraying of weed killer. To make his impact count, Jake distributed milkweeds to his peers at school for planting. Jake also planted milkweed in a personal garden and in a garden near his school. Jake’s solution helps contribute to Target 15.5 of the Sustainable Development Goals.

Think Before You Throw It

Union Colony Prep, Greeley, Colorado, USA

Mariah Glasper and Lana Coron from Union Colony Prep wanted to decrease the amount of trash found in their watershed. They learned that wildlife can confuse trash for food and that trash can also be detrimental to the quality of water as some of the chemicals from plastic waste can leach into our water. To address this issue, they decided to focus on littering that originates from drivers. Mariah and Lana purchased 100 reusable trash bins that drivers can keep in their vehicles. They strategically selected these bins because of their convenience— they were collapsible and easy to store. These bins were distributed to peers and neighbors. With this project, they were able to contribute to Targets 6.3 and 12.5 of the Sustainable Development Goals.

There’s No Plan Bee

Rocky Mountain High School, Fort Collins, Colorado, USA

The bee population is decreasing across the United States due to habitat loss. Their population decline could result in major effects on native plants and crops as bees play a vital role in our watersheds. Sadie Gudmestad and Evelyn Railsback from Rocky Mountain High School decided to take action by educating elementary students about these essential pollinators and how they benefit their watershed. Sadie and Evelyn presented to 150 elementary students in two different schools. Each student also received a kit containing flower seeds, a flowerpot, and a soil disc. With these kits, students were given the opportunity to grow a bee habitat around their homes to help address the decline in bee population. Sadie and Evelyns’ project contributed to Target of the Sustainable Development Goals.

The Problem with Menstrual Waste

Roosevelt High School, Johnstown, Colorado, USA

Olivia Chamberlain, Maerron Lovern, and Cassidy Poley from Roosevelt High School noticed a common theme in their lives; that menstrual products produce a lot of waste. These single-use products are some of the most common pollutants in watersheds, with tampon applicators being the second most common plastic found on beaches. These products take a long time to break down and have unfortunate implications on ecosystems. To address this problem, Olivia, Maerron, and Cassidy distributed multi-use period products, specifically menstrual cups, to community members and peers. Menstrual cups can last up to ten years, save thousands of dollars for consumers, and are better for the health of watersheds and communities. Ten cups were distributed to their community’s menstruators and an educational flyer on how they can reduce their period waste. Olivia, Maerron, and Cassidy helped contribute to Targets 6.3 and 14.1 of the Sustainable Development Goals.

Sustainable Rain Garden

Dayspring Christian Academy, Greeley, Colorado, USA

Jacob Riemer, Elijah Dougherty, Malachi Fast, and Jack Lawrence from Dayspring Christian Academy noticed that water was running off the streets and their school parking lot, carrying pollutants into water sources. Their school did not yet have a water collection system in place to help filter runoff water. That’s why this team decided to install a rain garden at the end of their school’s courtyard. This location was ideal for their rain garden as the water from their school’s parking lot often ended up in this area. Plants native to Colorado were planted in the garden. These plants require little water to thrive making them sustainable for the area and will play a vital role for pollinators. Within the first summer of completing this project, water has already filled this rain garden! This team hopes to incorporate some educational activities in the near future for the elementary students to utilize and learn at the rain garden. With their project, Jacob, Elijah, Malachi, and Jack contributed to Targets 6.3 and 15.9 of the Sustainable Development Goals.

Splish Splash Education Time!

Rocky Mountain High School, Fort Collins, Colorado, USA

Sayre Loy and Sophia Jess from Rocky Mountain High School found that water runoff can carry pollutants across watersheds. Through their research, they learned that improper use of pesticides and fertilizers, and improper disposal of waste and toxic chemicals can have major effects on a watershed and the organisms in them. To take action, Sayre and Sophia strategically installed a rain garden at Werner Elementary School on a sunny Saturday afternoon to help filter harmful pollutants in water runoff. To expand their efforts, Sayre and Sophia presented to elementary students on Earth Day to educate them on the benefits of having a rain garden and how they can take action to decrease pollution in their watershed. Sayre and Sophia helped contribute to Targets 4.7 and 6.3 of the Sustainable Development Goals.
